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

anyone ?
Already tried to replace like 3 different touchscreen digitizers - no luck - so i'm sure it is not digitizer malfunction....
Take it to service

Well I did it... Broke the screen a couple of weekends ago. Ordered and received a new one. (No problem and not too bad price-wise) Then I ordered the correct screwdriver. That came in yesterday and I followed a couple of tutorials online to take the thing apart. Not too bad despite the teeny-tiny parts. I got it back together and lo-it worked! Actually it took a couple of tries and I reflashed it but then it booted right up. All the apps seemed responsive and life was good once again...
Until I tried to make a call. Then the screen went dark and it appeared that the phone froze up. Called myself from the house phone and discovered that the Aria was dialing, connecting, and sending voice but that I couldn't hear anything on the Aria.
Disassembled, re-set the earpiece, reassembled, called myself again, and I could hear. The screen came on and stayed on, but the touchscreen would not function.
Disassembled, checked all the connections, and reassembled again. The phone appears to work correctly in all aspects until I try to make or receive calls. At that point the screen shuts down and the only way to disconnect a call (or get the screen back) is to pull the battery and reboot.
I tried reflashing the ROM and that didn't work. I'm afraid the transceiver is shorting the screen out somehow but have reached the limits of my expertise.
Any suggestions?
Thanks,
Jerry
I have never had to replace my digitizer so only speaking from what i have read but it sounds like the very small rubber piece that covers the proximity sensor. I have read that if missing or not placed correctly people have had the same problem as you. Just my thoughts
I've replaced my digitizer and I have had the exact same problem. E.Cardo is correct, it is the small rubber piece on the proximity sensor not positioned correctly or not present at all.
Thanks to both of you. The proximity sensor is supposed to be right behind the ATT logo, correct?
I can't wait to get home and try this. I really don't like the backup Cliq Xt... I'll post once I've messed with it.

It's hard to see them exactly so I took a picture to show exactly where they are:

It's actually just above the & in the at&t logo, although if you have a replacement digitizer, it might not have the at&t logo on it. If you have trouble seeing it, try looking at it in the sunlight.
To add to what drumist said there as small black rubber piece that goes around the proximity sensor that prevents light seepage and allot of people discard it by mistake when disassembling the phone.

Why did you have to reflash? The new screen didn't worked?.
My aria's screen is broken too. I boutgh a new one but It doesn't work. Do you resolve this reflashing? (that's mean applying the new rom version from ATT)
Thanks for your response.

The screen or digitizer are hardware they should have nothing to do with the rom. The op only tried flashing the phone to illuminate it is a possible source of the problem. It sounds like you did not install the new screen or digitizer correctly you may need to disassemble and make sure everything is connected correctly and securely. Flashing your phone will most likely not correct your problem.

Maybe, just maybe, there are new drivers for the touchscreen included in the rom. I am using cyanogen 7.0.3 without problems, and it works nice with the old screen.
Or the new screen is defective.
I am pretty sure I installed correctly the new screen. Of course the old one is working fine right now.
I requested a new screen so I will wait...
Thanks again.
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.
Hi,
I've tried a number of firmwares Europe/Asian/T-Mobile and my local Telstra Rom. But no success.
I replaced my smashed digitizer and LCD the other day, however everything works great, the touch response is inverted - Left to Right. All touches on the left side are responding as if I'm touching the right side of the screen. Everything in the middle is fine obviously but from there it's mirrored.
It's quite possible that because the digitizer was bought from the USA and its in a Telstra (T8697) phone, it's somehow incompatible.
By bootloader is stating the TOUCH is C1(v66)
Does anyone think they may have a solution to this? a Registry edit or some kind of Screen calibration?
Cheers for any help.
BTW - The digitizer capacitive buttons are also mirrored i.e. Back is Search and Search is Back.
This digitizer also has a circle around the Windows (Start) button. My old screen didn't have this..
same problem
Hi gauge41,
I have the same problem :crying:. Do you have a solution ?
I bought my touchscreen on uk by ebay.
Reference:

All updates have been done through Zune software without changes.
Best regards.

I've read somewhere, that there are two modifications of a touchscreen for mozart and they are not compatible, so if your previous digitizer didn't have a circle around windows button, but new one does, mirrored input is definitely because of that. Haven't heard of any registry tweaks to fix that, and I don't think you can fix it by installing different rom. You should probably get a compatible digitizer replacement or try installing different touch screen drivers.
Hi folks
Just inherited a very worn out one year old Xperia X10 from my son. Been trying to resurrect it.
About 2 or 3 months ago the touchscreen started to become non-responsive occasionally. Admittedly, I didn't look at it for him at the time. Then he dropped it down the loo (think - hope! - there was only water in it at the time). We dried it out in the hotpress and it worked ok but still with intermittent touchscreen not working.
He got a Blackberry from Santa, so a couple of weeks ago I inherited the Xperia. The screen was cracked in several places and totally non-responsive. Rather than chuck it in the bin, I thought I'd try and fix it up. So I bought a new screen on ebay and the other night I dismantled it and fitted the new screen. Touchscreen is still totally non-responsive. There was a slight rust on the perforated metal plate at the back of the screen which I carefully cleaned with WD40. All the connections and circuits look ok. I've updated it successfully on both PC Companion and SEUS.. I've also tried flashing using instructions from this forum but cannot get it right (most flashtool symbols greyed out). I have a feeling that it's a simple problem but just can't get there. The screen display is fine, I can get the camera and the keyboard up using the buttons. But damned if I can get the touchscreen to work. I feel the problem harks back to when the screen was intermittent - it still worked after the water/screenbreak, but not that well.
Anybody got any ideas or should I bin it? (Can't seem to get any worthwhile advice on the WWW - happened upon this forum while searching and thought - "This is my MAN". (One suggestion I saw on the web was to try a new battery - can't see how this would make a difference, present battery working fine. Also, I wondered if the proximity sensor could be on all the time?)
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.
