Is there any way to fix a flex cable? - Atrix 4G Q&A, Help & Troubleshooting

I was trying to replace my digitizer when I accidentally broke the flex cable, and now the touch screen doesn't work at all. I'm completely broke and unemployed so I can't afford a new digitizer, and I also need the phone working in order to get a job. So, can the flex cable get fixed by using either glue or something hot to attach both pieces together? Has anyone tried it before and succeded?
Thanks.

I'm afraid you're out of luck on the digitizer. Sorry.
It's not just a matter of sticking two pieces together, it's much more complicated than that. There are tiny electrical leads in there too which need to be connected to the appropriate spots on the digitizer. Even if you manage to hit those points, how will you keep it in place like that? You use glue and you've ruined the whole thing. In the factory they use tiny amounts of special glue that is then heat-treated to stick to the exact positions on the digitizer. Overall, the whole thing is way too intricate to be fixable at home. That's why nobody even tried it as far as I know.
Maybe you could try asking for donations?

[Q] Replacing Gorilla Glass Adhesive

Hi All, I'm one of the few who faced the problem where one side of the screen is slightly lifted on the edge. It doesn't cause any functional problems, but the springy feel is annoying. It's probably the adhesive on the left acting up and not sticking well. Press the screen down, and it will uplift within minutes. Tried the hot air method to melt the glue slightly, but no use.
So I probably want to replace the adhesive, and began looking for teardown guides.
None, however, really shows if the Gorilla glass can be pried off from the top ,leaving the rear un-dismantled. The flex cable should goes to the mainboard at the back, but I don't need to disconnect that for this purpose. I'm also not sure if I should pry the top or bottom.
If anyone has done it before, kindly share your experience here.
Thanks
Full replacement seems like the best idea.

oh. Why so? Seems like an overkill proposal...
I have the same exact dilemma. I see this is an old post, but maybe someone else can chime in. I really don't want to dismantle an otherwise working phone just to reapply adhesive. I like the phone but this seems like a really poor design.
Anyway, if anyone knows of a way I can reapply the adhesive without total dis-assembly I'd love to hear it!

sorry you cant, im replacing the digitizer for mine and u cant take off the glass without ripping off the flex cable for the digitizer.
i suppose u can heat up the adhesive and carefully open it alittle bit and put some glue on that corner. i say glue because you probably wont have room to put double sided tape and remove the second backing without tearing the flex cable for the digitizer.

Help removing Digitizer

So i dropped my phone and looks like i need a new digitizer. I have tear down the phone and the last thing i need to do is remove the digitizer but i have no idea on how to do it. Does anyone have any tips or links that show you how to remove it? I've seen this video http://www.youtube.com/watch?v=t8u5Wa3Odak but it doesn't show how to remove the digitizer. Any help would be really appreciated

At the end it shows you to heat up the digitizer to losen the adhesive that is holding it in place all around the edge. After that, slowly pry around. Do it really slowly though and let it work itself off, and don't use a sharp object because it will damage the sensitivity of the digitizer. Really patience is key. Don't rush it like I tried to the first time also be careful of the lcd underneath.
Just to reiterate what was already said, pry very gently, don't stick whatever pry tool you are using too far into the device, the LCD below will crack so easily. I did it when I did mine. Have patience, take a lot of time slowly working it off the adhesive little bit by little bit. There isn't any magic trick to this, it takes a lot of time and practice.

[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.

[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.
