I broke my screen and replaced it and now my prox sensor and accelerometer stopped working.
I replaced the screen a couple weeks ago and the sensors were fine, but the LCD had dead spots so I ordered a new screen and put that one in and that's when the sensors stopped working. Would these sensors be affected by the screen if it was faulty? I also noticed that I scratched the Motherboard flex cable while disassembling it (I don't know if the scratch occurred during the first or second screen installation though, since I only noticed it during the second time around). Could this be the cause of the two sensors ceasing to work? The scratch is about half a cm long and is on the same side as the sim card.
Thanks

it could be affecting the connection to these sensors from my experience of assembling / disassembling nokia 920.

Basically I'm trying to figure out which is the more likely cause. Im going to have to order a new part and I dont want to order the wrong one and waste my money. Any idea if the scratch on the flex cable or the screen would be the most likely cause? Thanks.

flex cable scratch can cause this, but so far i don't know how to change it - order replacement flex cable and then found out that it is glued / soldered to the board somehow.
I found there is 3M™ Electrically Conductive Adhesive Transfer Tape, which can be the solution for this.
Is that problem resolved?
I have a same issue.
I had the same issue. To fix it I had to do a factory reset without the SIM inside.

Hi, i have a thnderbolt and i recently replaced the LCD and digitizer. I powered it up and was working fine for a few minutes and then the soft keys stopped working and certain parts of the Digitizer. The LCD display id perfect and looks perfect. The parts of the digitzer/screen that do work, work great, its almost like its divided into zones. Ive done digitizer replacement before and i went back to check all the ribbon cables, none seem to be damaged or not connected. I dont know what to do ive tried everything i know what to do , please HELPPP!!

Sounds to me like your replacement digitizer is defective. I would check with RepairUniverse (or where ever else you got it from) and see if you can exchange it. If that doesnt do the trick the controller on the motherboard is probably bad and you will probably end up having to do a warranty exchange with verizon if you still can.
This is the 2nd digitizer I've broken on this phone. I took it off and replaced it. I put it back together and the digitizer did not work. I checked the connections and even took the digitizer off. I put the old, cracked but working, digitizer on and it no longer worked. I took the phone apart again and put the new digitizer on and it still did not work. Considering the old digitizer suddenly did not work, it must have been something I did to one of the boards or connectors on the phone. Also, the speaker no longer works. Any thoughts or suggestions on where I went wrong?
I can't guess what's the problem exactly but I can give you a few tips.
dissasmeble the phone according to the vidoes you can find on the web.
when you assemble it don't attach the digitizer to the screen yet. connect the digitizer first to the phone. then put the screen in place, with the digitizer still connected but not on the screen.
in this way you can test the phone before "closing" it.
hi there
I've got some strange issue with my lcd screen on my atrix. Everything is on this video(sorry for quality):
http://www.youtube.com/watch?v=bbMsmbblXLc
I don't know what to do- i don't have my warranty because of unlocked bootloader(in Poland they are very strict and surely they won't fix this on warranty.
So the issue is: when i touch near front camera/ front speaker the virtual finger appears. The second thing is that when i touch in showed area
there are 2 touches from one finger. It isn't a rom issue because it is on all roms i've tested.
If you have any idea what should i do please write it
Thanks in advance for any help
I'd say your digitizer is dying. Except unlike most others where a part of the digitizer stops registering touches, yours registers multiple touches. Either way, I believe buying and installing a new digitizer would fix this problem.
After a night which phone spent in home there is no additional touch in this line. Of course the issue with touching near camera didin't disappear.
Maybe it is because of very low temperatures in Poland nowadays and i think there can be some water inside of phone. But as you said
i'll think about changing digitizer

I tried to replace the front glass, (not very successful). I got the front glass off, but the LCD was still stuck to the screen, even after heating it up with a hair dryer. at first, none of the buttons except for power and VolUp and VolDn were working, so I took apart the phone completely, (MB, and screen/bezel assembly as one unit) and noticed that a connecter came loose on the touch screen link to the lower buttons. I got the home, menu, and back buttons to work again, but I still can't use the touch screen at all. It simply doesn't recognize input. Is there a way to fix the touch screen? It displays everything fine, but input via touch is now impossible. Is there a connecter that I may have missed? I would like to not spend $71 if I don't have to buy a new front screen/bezel assembly
You have a hardware fault caused by overheating the digitizer, replace the hardware.
It's quite common after screen replacement, which is why the screen assembly is the sold in one piece.

Well, now that I tore it apart again, and put it back together, the phone won't turn on at all. ****. Now it looks like I'm going to have to buy one. I'm now back to my backup phone, which is a i997 flashed with CM11 (unofficial) 4.4.4. Do you think I EMPed it by accident? Even plugging it in, it won't signify charging at all.
hi everyone,
I replaced a new LCD for my Z5 Compact... when I turned on the phone, the LCD lit up and work fine but the Touchscreen isn't working!
i bought it from ebay!
i cleaned the connectors, and i was trying reconnecting and i did that many times, and i think i did everything.. well, if im not missing something!
do you think is a defective unit or there is a solution for it?... the phone is still disassembled!
Thanks for any help or suggestion

Hi Nidhal
I have replaced whole screen with frame, but it seems to be used one (ordered from Aliexpress). It might be the case, I have two complete screens with same issue on my desk, but I dont know how to test them

you have to test each of them separately
take out the mainboard from the old chasis (frame) to test on the new lcd you bought (carefully unplug all the connectors)
then, connect the lcd and digitizer connectors to the mainboard, connect the battery too, and of course the power flex cable should be connected.. power on the phone, and see if the display lit up, then if the touchscreen works... and do the same with the second one you have and i hope you will have a working one al least
watch this video tutorial to avoid any damage
https://www.youtube.com/watch?v=hrOQoOSbldU&t=1s
and BTW, never buy these type of parts from aliexpress! would've been better from ebay or amazon because you'll be covered with warranty in case the part you buy is defected, and for that, you'll get a full refund or ebay will refund you if the seller won't
good luck
