white screen after fixed touch screen :(

Hi, i'v got a problem. I tried change my digitizer and, when im done, now lcd doesn't work, because it is still white...:/ What can i do now? any solutions?
Thanks a lot
Check your connections. Pull apart and re-seat everything to ensure everything is hooked up good.
everything is fine :/ still white screen
Perhaps you zapped or damaged the LCD when you were working on it...
You could try replacing the LCD too -- but at this point I think I would send it to the professionals
HTC repair or someone like PPCTechs
Don't know if the screen set up is still the same. But when I replaced the screen on my Universal the wiring for the touchscreen was stuck down onto the lcd wiring, as they both shared common earths. Maybe worth a check before spending more cash?
i have the same problem, the screen was working fine before i replaced the new digitilizer and now its just white but i can hear the tablet playing so it must be the screen.i checked all the wiring 4 times now! any idear???
:crying:
Slide the phone open and apply some pressure near where the angle of the opening is (back of the LCD below the SIM, where there is a bar). I had the same issue and this fixed it.

Can anyone help me?

Hi i have had an x1 since august but within a month its been dropped and then it was unable to show the screen, i opened my device to try and fix my problem but messed with nothing whatsoever, when i put everything back together it wouldnt even turn on anymore! all it did was charge and when it was fully charged there was a red light. can anyone help me? please im desperate to fix my phone. My first paycheck was spent on this and i loved it despite the numerous flaws! also i havent charged it in over 2 - 3 months. Also when i opened it the tape that connect the rear and the front is kind of messed up, would that effect anything?
The tape that connects the front and the rear is the cable for the screen, so if it's messed up, you might need to get a replacement.
here is a pic, the red part where its circled is where i think the problem is, it looks ripped off, i did have a hard time opening and putting it back together the first time also.
Sounds like (Or rather, looks like) you're screwed, as far as I can tell, if it's really ripped. Otherwise attempt to clean the contact points with some cleaning alcohol and Q-Tips - something might have made it's way in when you disassembled the unit and blocked the electrical signals.
ill try it, but if that doesnt work, would i be able to replace the flex ribbon? would acteone work?
got this checked out by my friend, he told me its the flex ribbon cable, thanks for the help btw. Does anyone know the cheapest place to get a flex ribbon cable from?
Still would like confirmation if its my flex ribbon cable before i spend 40 bucks on a new one. thanks!
Hi, I am new to this forum. Sorry for posting here but I think I have similar or same problem with my xperia. Few days ago I drooped my xperia and then I could not turn it ON. I opened unit, the flex cable was detached.
After attaching the flex cable. I could turn the unit and it booted normal but no response on touching screen I even tried to align it but it did not respond. I turned off the unit. After trying turning it back ON only back light of the screen turned on (no sony logo, no xperia logo no winmo).
I tried to turn it on few times but same result. Even tried to soft reset and hard reset it but no difference only back light. Is it because of flex cable or because some thing else? I can`t even go in to 3 color screen. Please help. Sorry for my bad eng. Thanks.

HD2 Repair

Hey guys,
The USB port of my HD2 broke off and I was forced to replace the motherboard. When I assembled the HD2 again, I could immediately see that there was something wrong with my screen. The screen couldn't display full color (only bright red/orange/white/dark green/cyan accents). Also, the 'hang-up button isn't responding anymore after I replaced the motherboard (and flexcable).
What happened? Is there something wrong with the lcd display or did something go wrong when I (dis)assembled the phone? I took the motherboard and the flexcable from another HD2 that had a broken display.
Thanks in advance.

So you completely voided your warranty through HTC and tried to fix the device yourself, then screwed it up. I'd still say send it to HTC and ask for a repair. I don't know if they'll do it or not, unless you used official parts. I know they do out-of-warranty repairs, but they'll charge you.....
Yep you screwed up the repair, those ribbon cables need a delicate touch & any handfisted moment ends up with what you have got now ...
Another careful strip & inspection of all ribbon connectors is needed ...
I bought it as a second-hand phone. The guy didn't give me a reseat and the HD2 was flashed a WP7 ROM.
For the button problem, how are you turning your phone on without that button? do you hear/feel it click when you press it? If not its just misaligned.the buttons are on a flex ribbon cable with two holes on each side. it fits on the plastic middle frame of the phone which has two small spikes coming out of it... it has to be perfectly placed for your buttons to actually click..
if the flex ribbon is broken however you can buy one off ebay for arround 10$ any will do, mine is not original works fine..
for the screen you could have messed up the lcd, did you separate from the glass-digitizer? if you did you probably screwed it up.. its not a easy thing to do.. also was not necessary for your repairs
the connection to the motherboard might not be all the in and clipped which might cause your problem... (being that two of the little pins provide voltage and ground while all the others provide data information if one of those pins is not in all the way a piece of data might not be displaying for example a color. Never seen that happen its theoretically possible thou)
well I have only opened my phone 3 times and dont claim to be a expert.. but this is my take on it... Good luck!
@pablow Thanks for the detailed response.
The HD2 is only turned on, after I place the battery. Otherwhise it won't start.
I hear a click on the (broken) 'off' button, everytime I press it. I also noticed that the inside of not all of the 'spikes' are empty. I can see a bit of the flexcable in the spike of the broken 'off' button. The spike of the (working) 'call' button is empty.
I think that the flexcable hasn't been connected securely to the motherboard. I'll try connecting everything again tonight.
not that it makes much difference but HTC wouldn't of fixed it through warranty because of usb damage anyway
I thought so, thanks for the heads-up anyways.
[Solved] Display is fixed
Update:
I disassembled the HD2 and reconnected everything (from coax to flexcable). Fortunately it worked! The display is how it should be.
I have another problem now. All of the buttons don't work now, exept for the dial button. Do these buttons break so fast? It's annoying as fuark, because I have to disassemble it another time in the future to fix the buttons.
I also couldn't re-attach the volume control tab when assembling the HD2.

Backlight problem after replacement

Hello everyone,
I have got one problem... I broke digitizer of my HTC Desire 500. So I order new one and to be sure, also LCD screen. I replaced, and...
After turning on, everything works fine. Digitizer works properly, screen shows normal picture. But after few minutes - restarts (I don't remember well) backlight of my screen goes down and now it have no backlight at all. I rebooted phone many times, I remounted screen and digitizer to be sure that connections are fine - but no results. I restored factory settings of phone with no effect too. :/
Please help, what happend? What could be the source of problem? I don't want to order new sceen if it could beak too ;/ I read other threats about coil problem in other HTC, but I cannot find any coil in my Desire's motherboard (maybe it is hidden under plate that covers CPU and other parts). I performed tests of light sensor and it works fine. Buttons lights fine too. The problem refers only to LCD screen, and backlight doesn't respond during test.
Anyone help?
same situation
Hello kowal_luki,
I'm just in the same bad situation.
After a bad fall of the phone the screen broke so I ordered a new one for replacing it.
Opening the phone I noticed that also the LCD (and not only the external screen) was broke so had to order also the LCD.
As precaution tried to power-on my device without a complete assembly and everything seemed to be fine, so I decided to glue the LCD to the outer screen (the touch screen) with a LOCA TP-2500 glue.
Then I re-assembled it up: at first the image was a little bit disturbed but the back-light was working; after few second the back-light turned off. I checked the cable, after that the image went perfect but the back-light still dead.
Did you find a solution for this -still not explanable- problem?

New display assembly won't work

HI guys,
I want to post on behalf of a friend who has a problem with his Xperia Z1. He originally bought it used with a broken display, he then changed it with success, the phone was working fine until it fell. At this point the display was still working but not the touchscreen, so he ordered a new assembly from the net (not genuine, like the first one which worked tho).
Upon receiving his new assembly, he immediately started the repair. However, when he turned on the phone, he only felt the vibration and nothing appeared on screen. No any light, he got a totally black display with no sign of life, while the phone was fully charged, and was recognized by Windows (he could even access his files on the memory).
He obviously thought that the seller tricked him and that the assembly was defective but when he tried with the old one (which had the display working but not the touchscreen), the same result showed up, no light, like the assembly wasn't plugged to the motherboard at all.
So far that's what I told him, check the connections to the motherboard, and make sure the flex ribbon is not damaged. He even bought a new ribbon and installed it, with no success.
He read that the problem can come from the display ribbon touching the chassis, thus making a short-circuit, but I doubt it. How if the display connector on the motherboard is broken? Is it fixable? Like buying a brand new connector and soldering it.
Thanks in advance for helping us
Try a hard reboot by Golding vol + and power until phone vibrates. Is the backlight working?

Thanks for reading this long problem
Sure, he tried the hard reboot thing, he even successfully flashed a stock ROM but nothing changed. I can only think of this as a hardware problem, but what part is defective?
The motherboard connector?
The ribbons on the chassis? But he changed to new ones already!
The LCD assembly? Same, the one he tried is a new one...
Still no one to solve the mystery?
I'd like to add that the phone turns off itself after approximately 30 minutes in idle state. That is, the explorer doesn't show the phone anymore and it has to be powered on again.
I know the best solution would be to buy a new motherboard or just forget about this broken phone, but it's a challenge to fix something that is apparently hopeless
