broken clip - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hey guys. I had to replace the digitizer on my wife's galaxy tab 4 10.1 thanks to the baby grabbing it and tossing it. When I replaced the screen, I was putting the ribbon cable back in and when I went to close the locking clip, it broke in two. before this happened, I tested the screen and the soft touch keys weren't working, which is the reason for the broken tab(I had to remove the screen to try and clean the contacts.) So, Now I am left with a digitizer that doesn't work and I'm not sure if it's due to this broken clip on the ribbon cable or if the screen was screwed out of the box. Does this clip allow for contact or just to secure the digitizers ribbon cable?

[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...

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.

Broke flex cable on S3?

got a problem, i have broken this cable on my s3 during a glass replacement repair, well.. it de-attached from the front glass?
I thought there had no cables attached to the front screen, does this power up the LCD? as I have no power to LCD now. even tho I did only 120-140C repair..
well all i know is there is one big cable that connects the screen to the power of the phone and one thing you learn is you do not break stuff while fixing a screen as it is a hard process requires being careful but you seem to have done 2 mistakes not just one :/
what answer to you expect? you need a new unit

Q: How to ground the display/digitizer?

Hi!
I have broken the display on my Z2.
I have ordered a new one online and changed it. Soon I realized it's not working properly (ghost touches and unresponsive screen). After looking for a solution, I found out that this may be a grounding problem.
Since i saw, that the new display didn't come with adhesive covers for the chips on the flex cable, i have fitted them from the original display, but the problem still persists.
So how do I properly ground the display?
Does the bottom metal part of the display flex cable, have to touch the metal part of the frame? I suspect that sometimes it doesnt (new display didn't have the grey adhesive, the original had - but I can't remove it). Do I have to fix it with some kind of conducting adhesive?.
What about the top metal part of the display flex cable? Must it touch (ground) somwhere or it's not neccessary?.
Do I have to be carefull that some parts of the flex cable doesnt touch some other part of the phone?
BTW, I know the display isn't faulty because if I remove the back cover, sometimes i get perfect screen rensponse (maybe i ground it with my hand).
Thanks in advance.
