Hi, i have a thnderbolt and i recently replaced the LCD and digitizer.

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.

[Q] Digitizer

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.

[Q] Atrix Hardware Problem Touchscreen

The top part of my Atrix would not fully respond to touch, and so I ordered a replacement digitizer for it. I installed the digitizer today and instead of the problem being fixed, the area of non responsiveness has increased, the 1 inch or so below the initial deadspot is also not responding. Also, the proximity sensor fails to turn off when I'm in a call and the phone is not near my face. What other hardware problem could it be that's causing the dead spot on my touchscreen and how to fix it?
I had the same exact problem when I first got my atrix and When I did a research on the issue I found out that I wasn't the only one and it turned out that it was a factory defect...if your atrix is still under warranty you shouldn't have any problem of getting a replacement
Oh man,
The problem is the boot loader is unlocked and I did go and replace the digitizer myself, so I'm pretty sure the warranty is voided. Any solutions or am I dead in the water?

hehe! Its kinda weird solution but it'll work! Just hard brick your device! If you are in gingerbread & flash any lower SBF the phone will be hardbricked. So you won't be able to go the bootloader state.
So then you talk to Motorola & say them you screwed things up while updating the set to GB. (Be a stupid in front of them)
They'll replace your phone.
Its not the great solution but it may work perfectly!

i did this..works:]
Had a cracked screen so I ordered a new digitizer. the old digitizer worked but was cracked all across the screen. I carefully removed the broken screen and replaced it. its now not responsive at all. I checked for damage to the ribbons but see no tearing crimping or other signs of damage, is it possible the replacement i ordered was defective? I mean lcd works great, volume rockers work in recovery but no touch response on screen.

I don't think thats the case because my screen was responsive with the damaged screen. I connected the ribbon clip several times to no avail. I am leaning towards faulty replacement digitizer. thanks for your response though.
Edit: the digitizer I ordered was damaged, I have since replaced it and it works great

P500 Touchscreen failure

Hello Guys
A question to those people who disassembled their LG P500
I Have recently replaced entire housing to a new one, including touchscreen digitizer(went from red body to white).
Everything went fine, however i did not aligned sensor rubber correctly and had to disassemble phone again. After correct alignment and final assembly, discovered that touchscreen does not work anymore...
Phone is working fine, but no touches registered.
Any ways to check correct contact between touchscreen and motheboard ?
tried several times, but no luck
any useful notes are welcomed
Thanks

[Q] Half of digitizer works after replaced with new.

I initially dropped my phone in water (sink), got out immediately and dried in rice. 72 hours later I powered up and all apps work, sound, making calls etc work. The problem is only half the screen works. I've replaced with a new digitizer and LCD screen. And still only half of the screen (same half) works. Do I have any other options? PLEASE HELP Please. My phone was purchased from AT&T if that helps.

Did u replaced the digitizer and LCD or u went to some service center?
Without knowing the problem and changing both the things blindly, surely, waste your money. If touch was not working buddy, then why u replaced LCD?
Okay, now its done, better move on.
If replacement didn't do any good, Then there might be a chance of other hardware problem... You can contact your provider's service center, they will surely look into this matter.

Thanks, I'll call service center. The parts that I replaced were free from a friend, so no loss of money. The screen was cracked from a previous drop but still worked fine and the LCD had a couple of white spots after it fell in the sink. So I changed both for reasons other than just the digitizer not working properly.

I also have been having touch-screen problems. Several parts of the screen don't respond to touch. I'd rather fix this phone than replace it.
I am running Android 2.3.6, kernel 2.6.32.9 [email protected]#2.
I see there is no screen calibration for this version.
I have purchased another digitizer screen but have not yet tried to install it. The ATT service center is not likely to help, as I have rooted the phone and enabled side-loading and mobile tethering.
Two questions:
1. Could changing to a later Android version and doing a screen calibration fix this?
2. How should I prepare for replacing the digitizer, other than a Titanium Backup?

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
