Water Damage - LG G5 Questions & Answers

Got the LG G5 Brand new, 4 days after it fell in the toilet. Got a quote for $600 repair, but only the backlight on the LCD didnt work, could see the screen with a flashlight pointed onto it.
Attached photos.
If only the backlight didn't work, it is probably the LCD screen that only doesn't work? If it was the mainboard, I would assume that other parts of the phone wouldn't work, not only the backlight. Meaning I should be able to replace the LCD + Digi without any problems? Can do the repair myself for $100USD

grab a fine tooth brush and brush the connector on the lcd and mobo with rubbing alcohol. let dry for a couple mins, then try the lcd again. my concern is the one component which seems to be missing solder at one end. you may be able to reflow the board but even if you got a hold of a new lcd its possible the issue with the backlight its on the mobo.

The missing connector that you see is the LCD Connection which is on the display itself, not on the Mobo. Im not sure why it would be missing, it did not look like that when I opened the phone to check it out.

And before the backlight went, it was flickering, so I am assuming it's the LCD itself, because IMO, if it was the mobo, it would just be gone, not fail over the course of a couple of hours.

No not the connector. The connector is there. I'm talking about a small component, that is missing solder on a side. I work with cell-phones and we get water damage devices all the time. Most of the time corrosion eats up solder and some components might need to be replaced. The connector doesn't seem all that bad on the mobo or lcd but like I said brush up both with alcohol and then give it another try. How long did you wait before you actually opened up the device to check it? Just by looking at the pictures looks like corrosion was building up for a while.

about 90 minutes afterwards. I put the parts in rice for a few hours after I opened it. Tbh, it looks like the quality of the image.

[Q] Guide on Replacing the Digitizer

Hi there,
I searched before posting this, but couldn't find anything for the Atrix...
Just wondering if anyone has seen/made a guide to replace the Glass/digitizer for the Motorola Atrix?
As to why I'm asking:
(If the image links don't work, you can find them as attachments to this post)
I've damaged the plastic around the glass (basically the housing, near the usb port) but I need to remove it from the digitizer...
I bought this: http://forum.xda-developers.com/attachment.php?attachmentid=572442&stc=1&d=1303199913
But as the ifixit teardown guide shows...
(http://forum.xda-developers.com/attachment.php?attachmentid=572441&stc=1&d=1303199913),
...When you take the phone apart, the glass is one with the housing.. Has anyone done this replacement of the digitizer or housing, if so, can you offer any suggestions, and what you used as adhesive to reattach the digitizer?
I've repaired the iPhone 3Gs and iPhone 4 before, both ranking higher in difficulty on ifixit's site, so I'm guessing the ATRIX should be a lot easier...
Anyways, any helpful tips or any guides would be greatly appreciated. I've already checked Google but no luck...

Try this http://www.ifixit.com/Teardown/Motorola-Atrix-4G-Teardown/4964/1
Or, this http://www.youtube.com/watch?v=TbR56jSplRs
Broke my digitizer and did the job myself using the youtube guide above. Just used straight up superglue to glue digitizer to frame. I put a bunch on the top and bottom and very little on the sides.
Amazingly the phone worked when i put it back together... for a while until I screwed up one of the ribbons by opening it a bunch more times. Be extra careful with these, especially the volume/camera ribbon. You can bend it pretty easily trying to slide it back into its slot.
Good luck.
NB: Theres places that will do it for as little as $90 in case you don't want to take the risk.

Thanks for posting the youtube link. I can't even quote the post because it involves an external link. The video was vague on details and the quality is crap but it did the trick.
My Arix got under the tires of a car (please dont ask how ) and only the digitizer broke, then i replace it with an OEM digitizer from amazon and now the proximity sensor is malfunctioning (Turns off the screen when im not near it or doesnt turns off when im near it), and there is a line of the screen that doesn't respond to tact. could it be the digitizer that came defective, or maybe it was the installation? oh, the other digitizer was broken and all but the light sensor was working fine and also the other thing. Sorry for my bad grammar.

I replaced my digitizer, and had the EXACT same thing happen (not the light sensor but the line in the screen that doesnt respond to touch).
Get a new digitizer, but get it from someone else.
That's what i feared, did you changed it back again afther that, and did it worked? and thanks.

No. I sold it and let someone else deal with it. Didn't have the time to replace the digitizer again. Too much of a hassle.
I just replaced a digitizer on an atrix... i didnt put any adhesive on it because there was what i thought was adhesive strips on the digitizer... but there's strips on the screen that doesnt respond, i heated it n tried reattaching the digitizer a few times n sometimes the home and back button will work, sometimes they wont... any suggestions? could the lack of adhesive cause this?
Menu buttons problem
if menu buttons is freeze till I block and then unblock my phone is it digitizer problem ?
what do you mean by " block/unblock" ?

Go the ifixit route!
Just went through 3 digitizers in my repair, and wanted to share my experience/caveats
I bought one digitizer from All4Cellular for $25, and the others with a 20% discount a few days later, for $20.
I installed
the first using the RepairUniverse Youtube 'how-to' method, and had a heck of a time threading the flex cables through the slot. Bent/twisted it too much, and nothing responded on the touchscreen, so I read some forum posts on how fragile they were, and regarded that as user error.
Got the idea to move the LCD screen from another RepairUniverse YouTube video and a previous post here, and tried installing the digitizer from the front face of the phone. It was still a delicate matter to bend the flex cable so that it fit through the slot, and then re-position the LCD and align the sticky strips of the digitizer on the LCD and casing. Part of the digitizer worked this time - a 1cm vertical strip on the left fowled any attempt to touch icons or use a keyboard, so I thought I had damaged things again (doh!).
Hoping third time was the charm, I completely disassembled the phone using the guide in the 'ifixit' link, since a digitizer/case assembly was suggested in another thread. The rear camera just needs to be raised above the casing so the thin plate can move upward, and the LCD pops out easily if the sides of the casing are delicately pulled. The digitizer can be positioned easily and with minimal bending/twisting of the flex cables.
When reconnecting everything the third time, I noticed that pressing down on the front camera / digitizer connection *with the rubber boot in place* didn't pass when pulling the connected assembly upward. So I pulled the rubber boot out of the way and snapped the camera / digitizer connection firmly, then re-inserted the boot. A loose connection might have been the culprit for the nonfunctioning part of the digitizer in the second test.
@MrSaba - I had the same issue with capacitive buttons - perhaps because the screen senses touch and disables those buttons. Replacing the digitizer solved the issue
trouble
Hello friends,
Here's my story - broke a screen, as usual slipped from my pocket. though broken, digitizer worked fine. after replacement with new one (digitizer only) - no luck it didn't work. bought a new one, this time with a plastic part around it to avoid damage to it's cable. after careful repair no luck once again - does not work at all. downloaded a testing app (i was able to remote control the phone with a piece of soft called androidscreencast), everything is ok, except digitizer. checked and rechecked all ribbons and connectors 10 times, nothing seems to be broken or twisted.
what's your opinion, is it worth buying third one ? what part of my repair went wrong ?
thanks

Not all digitizers are created equal. The ones that ship with the red stripe on the backing are junk. Spend more money and yes buying with a frame is key. Did you try reinstalling the original screen or did that ship sail already?

The first one was with the red stripe indeed, from china. The one with a frame came from UK, "used but tested OK". original screen is gone - tore off flex cable while removing.
Well, update...
2 screens bought on eBay were BAD. Had to wait full month for authorised motorola service to change the digitizer. Must say though that both merchants on ebay refunded, no questions asked. Lessons learned - pay more, wait longer, never give up

What I noticed on their video was that their folded digitizer connector magically unseats itself during the disassembly transition. I had to pry mine off based purely on guesswork and think I might have broken the flip-chip that is stuck onto the frame with double-sided tape. Like yours, my touchscreen doesn't respond at all, despite there being no cable tears. I'm going to try and re-heat that flip chip and maybe get the connections to work again (doubtful).
To anyone else out there attempting this... when you go to remove the touchscreen, HEAT THE CONNECTOR so that you can gently pry it out!
Bad screen I got 3 before it worked its fine now if old one partially works new one doesn't screen is junk took mine apart several times to figure out screens were junk...guess they felt sorry for me give me my money back plus free working screen.from amazon
Also that lock clamp u mentioned first video I watched didn't show unlocking that I just pulled it out and pushed back in it was the 2 screen that I figured out it needed to be pryed loose by the white clamp but guess I didn't damage it..

I have just put in my second digitiser. The first was one had a red stripe, which was junk, the second on I bought had the plastic round the edge and the digitiser.
I put it in and it worked fine no dead spots at all. Then 12 hours in it started to stop working intermittently. Then 24 hours after that while on charge its dead again. I reflashed notattrix and still nothing. I've confirmed all the ribbon connectors are firmly in place and everything looks right.
Any ideas whats wrong?

[Q] Replaced Digitizer ... Did the LCD break or ?

I just preformed a digitizer replacement for the Thunderbolt. One of the ribbon cable Zero Insert Force partially chipped off. Can you tell me (from your personal experience and intuition) if the symptoms look like a broken LCD screen, or the bad connection from the ribbon cable to the main board?
I've heard bad things about trying to do the digitizer only without the LCD, but the partially mangled connector throws me off on what it might be. To be more specific, it looks like the ZIF release bar was weak and 1/2 of the bar broke off. The other half of the bar still 'clamps' down.
Thanks a ton!
That's really odd. I've only worked with cell phone repair for a company for 4 months but from that I might be able to help. First... A few questions... What did you use to melt the adhesive? If you did that improperly this "could" potentially happen so that would make it an LCD issue. It doesn't look like an LCD issue other then that unless the pins on the ribbon cable connector are screwed. Now for what I personally think it looks like... Did you forget to remove the screen protector from BOTH sides of the digitizer? Or did you not clean the LCD and digitizer in alcohol after handling them?
My advice is to take apart the phone again, and turn it on while holding the cable connector in place to rule that out.
Now I haven't repaired the thunderbolt yet so when you say you broke the connector, is it a hinge connection and you broke part of the hinge? Or a snap in connection and cracked it? If option "B" its your LCD without a doubt.
Edit, sorry I didn't read the end. So it is a hinge connection. As long as the entire clip is ALL the way in your fine. If part of it is up and won't stay down... A small amount of electrical tape never hurt.
Edit number 2, absolutely not a cracked screen. If you would have cracked it you would have known, and it would look a lot crazier.

Yeah the guy above knows a lot more than me but to me it looks like a bad connection.

LCD not functioning after DIY glass replacement

Just finished replacing my cracked glass / digitizer, but now my previously working LCD just shows vertical colored lines. I bought one of the glass / digitizer replacements from Ebay, which was a perfect match for the OEM piece. Since I was having trouble finding the thin double sided tape, I used black silicone adhesive to bond the LCD to the digitizer. When I plugged in LCD panel and turned the tablet on, all I get is vertical varying colored lines across the LCD. I've pressed the on /off switch for 10 seconds to reboot the device, but it still does the same thing. I've taken the ribbon cable off and on checking to see if was not properly seated, but it seems to be okay. Any ideas?
The ribbon cable had a 90 degree bend in it after it was removed... can that cause an internal cut in the cable itself? At least to me, it appears that the LCD is working, since the lines are bright in color and even change as you manipulate the digitizer... it just has no picture.
Thanks..

90 degree bends can cause one or more of the individual conductors to become broken. I've had it happen on hard drive cables, and one inside a sprinkler system once.

Any way to actually test this? Can use a voltmeter type tester to check continuity from one side of each pin to the other? They are hair like in size, so not sure the standard tests are the same.

My DIY experience...
Hi,
How did you perform the screen replacement? I have tried and I have described it below.
It seem like there are a lot of people that has TF201s with broken screens, but very little information about how to DIY screen replacement, so I wanted to post my experience here.
The screen on my TF201 cracked (dropped on the floor - only the screen was damaged, the LCD and digitizer still worked) so I seached around the web to find ways to replace the screen - without luck
I did find instructions on how to open the device and I also found original glass/digitizer replacement parts on eBay originating from China at about $100 so I took the chance and ordererd a new screen. It arrived 2 weeks after and looked good.
With the instructions on how to disassemble the TF201, it was quickly open and the glass/digitizer/LCD is one subassembly connected to the mainboard with two flex cables - one for the LCD and one for the digitizer.
Next step is to power off the system internally. There is a small internal switch in the lower left corner that you should switch to the off position. The LCD and digitizer cables can now be disconnected from the mainboard. The connectors open easily by putting a nail under the white frame of the correctors and pulling the frame up and then pull out the flex cables. You now have the glass/digitizer/LCD separated from the mainboard.
The LCD has a few screws to hold it to the plastic frame - these should be removed at this step. Mine only has two screws mounted although there are room for more (bad assembly quality or a fix for screen bleeding???)
Now comes the hard part and the part where I failed! There is a plastic frame around the edges of the glass that you need to remove and mount on the new glass. This plastic part holds all the taps that keep the tablet together and it is taped to the glass with some VERY sticky tape!
I used a knife to cut between the plastic and the glass with the result that the glass broke in tiny pieces as I went around, but as I saw no other way I kept going... It might have been better to use a heat gun or a hairblower to heat up the glue before trying to remove it, bu I was worried that the LCD might be damaged by the heat.
The plastic frame has to be removed first to have access to the foam tape that is used to tape the LCD to the glass/digitizer. Once the plastic frame was off, I again used the knife to gently cut the foam tape (around 1 mm thick) all around the LCD screen so that this can be removed from the glass.
Here I might have made my second mistake. I was worried that I would cut too deep into the foam and hit the LCD screen, but the foam at the bottom of the screen is a little wider than the rest and as I tried to remove the screen I used too much force and might have damaged the LCD - the end result was that also the LCD was damaged in the process. The damage might also have been caused by me pressing too hard on the screen during the removal of the plastic frame (might actually be more likely as the glass was broken across the screen and the damage I was seing when I turned on the screen was following the same line).
Well, I got the LCD off the broken screen and though I had been successfull even thought it had taken a couple of hours to get there (I could not visually see that the LCD was damaged at this point). Then on to the assembly with the new screen/digitizer! I had some double sided tape that I used to tape the screen to the plastic, but desided to to a quick test before I fully assembled the unit and this turned out to be a good idea!
I mounted the LCD screen with just the screws and connected the flex cables back into the connectors (these can be a little tricky to get it, so just be patient and keep wiggling them in and close the latches). I enabled the power again and pressed the power botton and: DAMM - THE LCD IS BROKE!!!!
After wiglling a little with the LCD cable I was able to get a partial image, but it was evident that I had mishandled the LCD screen during the disassembly and I needed a new screen to gt my tablet working again - now I was glad that I did not glue the LCD to the glass, so that I needed both a new LCD and a new glass/digitizer!
Off to the web to seach for a replacement LCD screen... Hmm, lots of ebay listings for replacement LCDs, but none of them looked like the original I had, but when seaching for the partnumber on the LCD I took out (Hannstar HSD101PWW2 rev. 0-A00) I did find a few priced around $100
Before I started to spend more money on the device I wanted to check our if the digitizer was actually working, so I connected the tabled to my TV using the HDMI output to test...WHAT?? THE X-AXIS WAS REVERTED!!!
I double checked the flex cable connections, but everything was in order. I then compare my broken screen with the replacement part and noticed that the signal routing on the flex cable for the new part looked quite different than the original.
I emailed the company that sold me the screen and he replied back that they JUST heard that some other customer have had the same problem - there might be different versions for the digitizer used in the TF201 (perhaps depending on production time)!!!
He suggested that I tried a hard reboot and a system reset to default and I tried that without luck.
I also tried to find a 5 point screen calibration routine, but this does not seem to be supported.
Does anyone know of a way to revert the x axis by modifying a configuration file - and can that be done without rooting the device??
They did offer to refund the price of the screen if I shipped the screen back to them, but I will most likely damage the screen when trying to remove the plastic frame and it will cost me shipping the part back to China...
Did you test if the touch screen is actually working on your reworked unit (you can use the HDMI output as I did)?
Unless I get the screen issue resolved I most likely will get a TF700 instead of my broken prime - I really loved the prime for the 4 months I had it working...

I was in the same boat as you... after I took apart the unit, I still had a functioning screen... but when I went further to separate the LCD from the digitizer, I must have damaged the LCD. Right now all I get are vertical colored lines. I need to get an HDMI cable so I can check the function of the digitizer.. It seems to work, because I do get color changes when its manipulated, but no image. Damm.. problem is... how much good money do I spend on a damaged device.. At this point, I wish I just sent it in to get fixed by Asus..

I'm not sure that your LCD is broken. It might just be the connection to the motherboard that is bad as chamberc said. I had the same problem with my broken screen. I had to wiggle the cable to get a partial correct picture on my screen. I tried to clean the pads without getting a 100% stable connection so I might have broken the flex cable as well, but normally these are relatively good at flexing without braking (they are made to do that) so I tend to think that it is the connection in the connector.
Until I figure out what to do with the touch screen I have not spend more time on root casuing it, but I suggest that you try to take the flex out of the connector and clean it with either a erasor or a cloth with alcohol and then gently put it back into the connector. Also ensure that you put it in the right way and close the hatch properly.
Good luck.
On the touch screen issue, my touch screen is working fine it JUST has a reverted x-axis, so it would still cause your colors to change, so I'm very curious if yours is working. Could you also share the touch screen part number (printed on the flex cable) and TF201 hardware version (TF201-1B or TF201-1I or???) This should be written on the label of the box and on the warrenty card.
The background for me asking about this, is that asusparts.eu has different spare parts depending on if is for TF201-1B or TF201-1I so there might be two versions of the hardware out there. Mine is a TF201-1B.

[Q] HTC Rezound - Digitizer replacement questions

Just 35 minutes ago my phone fell from my hands and onto some cable in the perfect way that it broke the Digitizer. Wonderful. So now I have to go about replacing this. It looks pretty straightforward and I will be doing this but I have a few questions I'd like to see if I can get answered. Perhaps this can be used by others as a helpful FAQ regarding replacing the LCD or Digitizer on an HTC Rezound.
1) I know I will be needing the Digitizer only as the LCD portion is not broken, so can anyone give me a good reason why I should replace both and not just the digitizer?
2) I know there are some adhesives involved in holding it together. Are these re-usable or should they be replaced? If they should be replaced, what kind of adhesives are they and where can they be found?
3) What is a good source for these parts? (Adhesives and digitizer)
4) Is there upgrades here I can do? Like a gorilla glass digitizer or something?
5) I've read a guitar pick is a great tool to separate parts, do you agree?
6) Any Gothca's that I should be concerned about
Here is the procedures I will be following:
1) Remove the back cover, the battery, SIM card and SD Card
2) Remove the 6 T5 torx screws around the sides (from the back)
3) Pry up the back by releasing the plastic clips around all 4 sides (note the volume rocker/power button may fall out)
4) Remove the Vibrator motor
5) Remove the two screws holding the MoBo on and lift up from the USB port side and remove the plastic piece from there.
6) Release the small plastic clips holding the Mobo in and swing it up, release the two ribbon cable connections
7) Heat around all sides front and back to loosen the adhesive, from the back work with a guitar pick to loosen the adhesive, repeat this process from the front.
8) Work around with the guitar pick between the screen and the housing from the front and remove the LCD and digitizer from the housing
9) Heat all the sides of the LCD/digitizer to loosen the Adhesive
10) Work with the guitar pick around the sides to release the digitizer from the LCD screen. It seems there is a piece of black tape on one side, you would have to "butterfly" the two screens and peel the screens apart.
11) Done. Reverse these steps to rebuild it. Do these adhesive parts need the adhesive replaced? Does the tape need to be replaced?
I cannot post links yet, but I felt I should give credit where its due. To obtain these steps I used a Youtube video. To view this video, search youtube for: 'How To Fix HTC Rezound Screen by RepairsUniverse.com'
The advice from the experts is highly anticipated!!

The best reason for replacing both is that you won't have to worry about binding them or getting dust between them if you get them together preassembled. As to the rest, I can't say. I know we have a few people here who have done it.
So I found the adhesive strips that I need. It comes as a bulk sheet where you cut them to fit. I am going with replacing only the digitizer. Replacing the LCD screen also would male the process easier however I fear getting a replacement screen that is in worse shape or more poorly made than the original one my phone came with. I know this one has no flaws.
So I have answered my questions already. I'll post here when I done replacing the digitizer with anything that is of interest in case someone else has questions about this procedure.
Thank you for your input shrike1978. Much appreciated.

Check out my thread: http://forum.xda-developers.com/showthread.php?t=2189789
I did it not long ago, and was fine. However, I opted to go for the digitizer + LCD assembly, as I didn't want to have to worry about separating the digitizer from the LCD and worrying about dust.
To answer your questions:
1) It's eaiser, takes less time, and you don't have to worry about dust with replacing the digitizer + LCD assembly.
2) Replace the adhesive. I tried reusing it... and it has some flex on it. So I got some new adhesive, scraped the old stuff off, put the new one, and used a heatgun to move the screen assembly around to get it to fit right, and then pressed it down as it cooled to secure it better.
3) Ebay
4) Not sure on this one... not that I know of anyway.
5) If you get the parts from eBay, then they sometimes come with tools (Torx, philips, and a plastic separator tool).
I also linked the video that I used in my thread, so you can look at that. It's pretty straightforward and easy to do. Took me about 45 minutes to just over an hour to do everything, as I was taking my time.
Well I did this process two days ago and for the most part it went well, but not without its issues.
First off, I should have heeded the advice of others suggesting to get the LCD + Digitizer pre-assembled. I tried to save some money however now there is a dead spot on my phone and I will have to spend that extra money to buy the kit anyways. So for anyone else thinking they can get away with just the digitizer, unless you have dustless neoprene gloves and a clean room (or possibly nitrogen or canned air) and lots of experience, do not attempt to replace one or the other, just get the pre-assembled kit.
I am going to replace it again with the kit in a few more days.
The only thing that came up that I didn't see anywhere else, was when I was pulling the back cover off. The spot where the camera is located was kind of sticking to the back cover. If I would have pulled to quickly or was too rough I would have easily damaged the camera. So my advice would be to work slowly when pulling the back cover off. If it feels like its resisting, it could be your camera. Wiggle it slightly and don't force it. The camera will loosen itself from the back case, but using too much force you could damage it.
Thanks for the info guys! :good:

I also purchased the full assembly and was able to switch the new parts onto my Rezound. Unfortunately, the earpiece (the part you listen to when NOT on speakerphone) and the proximity sensor did not work with the new set, and I am swapping it for a replacement. However, I've been inside the unit now 5 times, and I suggest in addition to the tools supplied with the sets (t5, small phillips and separator) you also have a small flathead (helps with starting the split the unit apart and also with pulling and reattaching the vibrator motor) and a long tweezers (invaluable when trying to reconnect the ribbon cables.)
Also, reconnect the MIDDLE ribbon cable (which is slightly twisted and longer) first, then reconnect the top, and don't forget to reapply the insulating tape (been there, done that).
Watch the take apart video on Youtube repeatedly until you can do it with your eyes closed, and be careful, the red plastic does break easily, especially on the corners.
Replaced my digitizer with good success, using new adhesive. Upon first re-assembly the digitizer was popping out of the plastic bezel a bit, but everything worked great, touch, display, everything. So I decided to take apart, add some more adhesive strips. Now the digitizer stays flush.
First boot after 2nd re-assembly, got boot with first vibrate, but no screen on. So I pull the battery to attempt again. Now I receive no vibrate response from power button. When plug into charger, orange light comes on for 5 seconds and then off indefinitely. This happens each time after battery pull+wall charger plugin.
I have tried multiple times disassembling, checking both ribbon cables that plugin to motherboard, appear to connect fine. Visually all other aspects of MB appear fine.
Any ideas anyone? Not sure what may have broke. I should have left well-enough alone, but the digitizer was somewhat spongey to touch on right side of screen and I could see white light shine up... TIA
Each time I pull the batt the orange light will come on solid for 5 or so sec, then off for good. One time even started flashing for a bit like it was charging from full depletion (like it does before it lets you power on). Not sure how to diagnose.
Did you make sure to put the yellow protective tape over the ribbon cable connections? When you open it (like a book) and see two ribbon cables. There originally was a small piece of tape over the connection to provide protection from anything being shorted out. Make sure this is back on.
If you no longer have the tape, I think any non-conductive tape would work like plain Scotch tape. Please correct me if I am wrong in that statement.

I did not put those pieces of tape back on. In the YouTube video by "injured gadgets," I don't believe they re-covered up those ribbon cable plugins, so I also did not during re-assembly. Should I try that? Or, I assume, my board somewhere has gone bad? (Phone did work just fine after re-assemble, until I decided to take apart again)
And after doing this a handful of times, I figured out that the "earpiece" doesn't come with the digitizer/LCD/housing. It has to be pulled from the old phone and moved to the new one. Once I did that, everything was fine.

hgoldner, when you had forgotten to re-apply the insulating tape over the ribbon cables, did that result in a toasted motherboard? I'm trying to find out if that's what happened to mine? Thx

I would go ahead and try putting it back on. There was an earlier post where someone mentioned it was important to put it back on, perhaps he can comment on what can happen if its not on (He said he learned from experience). Perhaps you can PM him.
To be honest, I originally only put the tape back on one connection, but after the second time replacing both the LCD screen and the digitizer, I found the second piece of tape and now both are back on.
What can it hurt to see if that will fix it? Its fairly easy to get to on these phones.
Ed
Yes I did try put back on, no worky still. I assume motherboard issues now. So now I ask if anyone that has also failed to put tape insulation back on, has also resulted in motherboard fail?

I ran it for about a week or so without the insulating tape. I assume you just mean the translucent, amber tape that goes over the jaw connectors of the ribbon cables on the motherboard? Not putting that on shouldn't have damaged your board... it's really just there to keep the jaw connectors from opening from vibrations.

I left it off on one connection for about a week also with no issues. However I did notice roughly a 16th of an inch of copper exposed on the ribbon. I can envision potential issues from that. I'm not sure about your phone, but the jaw connectors on mine would never open on their own. Far too much resistance to open from any vibration or movement. The vibrator motor connection had a better chance of disconnecting on its own than the ribbon cables. I'm sure that tape provides more than just locking the jaw connectors closed. I could be wrong though.

No, I remembered and put it on before I powered up.
Dumped down the innertubes from my Asus Transformer TF300T
Just replaced my digitizer two days ago and I must add the difference is like night and day. I noted in a post that I had tripped and fell on it with my knee...lol ..nope.. I threw the damn thing and it hit the wall. Yahhh.. I know stupid lol... Something really pi$$ed me off tho and I kinda lost it.. .poooof....... Anyway, I had about 30 cracks in my digitizer and amazingly it still worked. Replaced it two days ago and it works great.
That factory adhesive is some SERIOUS stuff. I have performed many electronics repairs over the years and this...well...removing the digitizer and applying the new strips in exactly the right size was a royal pain in the a**! You REALLY gotta get that digitizer glass HOT if you want to be able to loosen it. Light heating WONT do squat to it. And the new strips arent even half as strong as the factory stuff. You really need patience and precision here.
Yes, dust ISVan issue where I live. Canned air came VERY useful. Also its good to have isopropyl alcohol and soft paper towels so you can clean any smudges you make on the LCD before reapplying the digitizer glass. Basically it's best to blow air over it quickly as you press the digi down to the adhesive. That makes sure every bit of contaminant is out.
About the ribbon cables, no I didn't reapply the amber tape to the jawbone connectors. Much of their adhesiveness was lost when I pulled them off. And as long as the ribbon cables are seated in properly and the jawbone connectors are securely locked down, they wont come disconnected. The tape is only there as an additional measure to secure the jawbone connectors from unlocking. Unless you drop your phone on concrete a lot, those cables arent coming loose....even then, dropping it wouldnt knock those loose.. Its more secure than you think. As far as the phone NOT working, the orange tape would have NO effect on that. Maybe one of your cables were partially disconnected and shorted out something on the mainboard. Either that, or it is static sensitive. Its possible if anything is CMOS.
ONLY issue I have since the repair is the top of the digitizer keeps pushing up because of the digitizer ribbon cable and where you have to bend and fold it in that groove to guide it behind the LCD . The ribbon isnt pinching down well and acts as a spring on the digitizer glass....adhesive not doing anything for that.
oh, did you all remove and reapply the clear (4 button tabs) at the bottom to the new glass? got mine in (the lights are pink now ...weeee ) Had to use some Gorilla super glue to restick them. That adhesive at the bottom was super strong and somehow they lost their stickiness when I pulled them off.
Digitizer after I finally got it unstuck from the LCD... wheewww damn. Lots of cracks. Thats what happens when the phone face eats the wall.....
So, my 4 soft keys on the bottom have yet out. Would fixing the digitzer get them back to working? My screens just got cracked like 2 days ago too, and I just want to make sure before i do all this and then find out i gotta take it all apart again. Thanks in Advance!

You can't fix this by yourself, unfortunately. It's glued on with some special adhesive, the contacts are to tiny to solder. The glue you buy on ebay (i assume), next problem is getting the flex cable on the right place and keep it their while glueing.....
You can look for a motherboard replacement, only last time i checked it's almost as expensive as a new phone.
Some manufacturers use small clamps for the flex cable, i assume glue is the trade off for this tiny device...
I've been to this hassle myself, i ended up on buying a new ultra
Has someone have any other suggestions? Have detached the main flex from the board. Had the main flex broken, wanted to fix, but know it's just disassembled. Had display problems before.
Can someone have some ideas? like those clamps you mentioned.
Bro your beating a dead horse, just buy a used one online
hot bar soldering attachment, anisotropic adhesive film/tape( apparently you can buy this for whole sale only. lucky for me the company I work with has spare trimmings of this), microscope or powerful magnifying glass and a lot of patience.
bump, i am in this boat, there must be a dozen lines on the cable, i cant imagine soldering it without shorting it out....
Why do they sell those toys that cannot be repaired by the way?
I'm in the same boat an all y'all being no help are no help so bump outta here already cuz everyone else in this boat looking for the answer doesn't wanna WASTE THEIR TIME on your helpless posts.
To recap we have the solder method which sounds like rubbish as flex cables melt.
Then there's that kind of adhesive glue and/or tape. Clamping is the reason phone companies profits dwindled until they switched to this new clampless method. I'm not gonna buy in bulk cuz I'm not about to start up a cell phone chop shop so maybe get a magnifying headset, some Walmart super glue that says mess free, and use a needle to dab the glue on in the right points but don't cover any contacts!
Did anyone ever managed to get this done?
I also recently experienced, looking at google solution does not get the information.
Try YouTube? I'm sure it applies to other z models

I just did this. I didnt use that ADH* glue some people are talking about. I simply inspected how the old one is soldered on. Then removed the old one. There will be slight residue of the glue people are mentioning. I just simply took the solder tip OFF my soldering iron. then used a magnify glass to align the new ribbon. I also used clear tape to hold half of the ribbon down. Meaning i did 1 side at a time. So i taped from the middle to the far left to hold the ribbon down. I then used the blunt end of my soldering iron with the tip removed to press down with some force. Stayed in one location and counted to 20 the slid a little bit to the left. repeated this till the right 50% of the ribbon seemed glued down. I then applied clear tape over this portion and moved over to the previously taped left side. Repeating what I did on the right. after about 10 minutes of work. attached battery, press on button, phone came on. Then tested volume up and down and all worked.

Can u explain me how u attached the flex cable back to its place. I didnt full understud this explanation. Have the same problem hoping u can help me.
using the soldering iron t shape tip, step 1 using the scraper to scrap away the glue then install the silicone strip to heat the flex cable on the board. hope this help.
Have same problem too! When I transferred the board with the power/volume button flex cable to a new housing, I accidentally lifted part of the flex cable causing my XZU C6833 not to boot up, no vibration and no screen image.
And can't seem to find any tutorial on how to properly attach the said cable onto the main board.
Will try lesterine's solution.
