Xperia Z screen problem - Xperia Z Q&A, Help & Troubleshooting

Hello, I got a Sony Xperia Z (C6603) whose touchscreen was not working. So I change the LCD screen + touch. Everything worked properly until the screen starts to malfunction (ghosting and bugs of all kinds). So I disassembly the phone and I was surprised to see that the connector of the LCD was slightly torn. Then I bought an LCD screen + touch glass, other than the previous one. I ride and then everything works again .. until last week. Same problem, so I disassembly again and I see that everything is in its place, the connector is not torn, nothing ...
I wonder where does this problem. Note that I have tried to put to factory reset the phone (via settings or Flashtool), I downgrade to Kitkat, in short, I tried everything as well as hardware side software, nothing doing.
If anyone know where it can come ... Thank you

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.

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?

[Q] Phone is crashing after the call

Hey recently I changed my digitizer in Xperia SP. I opened it up, threw away the old digitizer and sticked the new one. Only the most superficial layer. Everything else remained the same. After that I noticed slightly worse touch sensitivity but I thought it might bea common thing since it isn't the stock digitizer anymore. But after some time phone started to act wierd. Sometimes it becomes unresponsive to any touch, I must reset it with the button from behind. It occurs especially after the phone call. Anyone know why it can happen? Power button works fine, also the volume up/down.
I had the byagusz's cyanogenmod11 and I thought that maybe it is because of the system but I replaced it now with stock rom and the problem is still there.
Is it possible that I didnt connect everything properly ? Should I open the phone again and correct every tape ? Please any help is needed

LCD dead after replacement

Hello.
I have bought a faulty Xperia Z off the market,the screen was broken so it didn't work,but everything else did,as I could connect it
to the PC and take screenshots via hardware buttons,so I ordered a new screen for the phone.
I replaced the screen,but I tore the battery a little bit,on the outer metal "paper",now the phone turns on,
you can hear everything,but the screen is dead,although it's new.
I tried to hard reset it,update the software,repair it,but no help.
Also,could it be the battery,so I can order a new one?
How is the LCD powered on Xperia Z?

Replacement screen doesn't work

Hey guys,
I've searched and tried seemingly everything, but can't find a solution to this problem. A few months ago, my cousin dropped her Z3C on the floor; the screen cracked and stopped working. I got and installed a replacement screen, but it doesn't work. When I first turned it on (after charging the phone for several hours), the display was off, but I could touch the screen and I would get haptic feedback.
When I do a soft reset (Vol Up + Power), it vibrates 3 times, but the screen still doesn't display anything. I've pressed the little yellow reset button next to the SD slot, which also causes it to vibrate, but the screen still doesn't work. When I connect it to a PC, it is identified, though no folders are shown in the device. After I used the repair function of the Sony Xperia Companion, I now no longer receive haptic feedback when touching the screen. I also tried using flashtool, but to no avail.
Can anyone point me in a direction with how I should proceed?
Thanks!
It may be a motherboard issue now,try taking the phone apart and reconnecting the screen,but don't close it fully just connect it and see if anything happens,if it still doesn't work it could be a motherboard issue or you got a DOA screen
Make jumper on fuze like I did on 2nd picture and should be fine. Pictures here.

Click to expand...
Click to collapse
Unfortunately, soldering for me isn't an option.
I've looked into the price of a motherboard for the Z3C and it's pricier than I expected. I might just cut my losses and try to sell it as is.
Thanks for all of the suggestions, guys!
