[Q] Xperia Z faulty display? - Xperia Z Q&A, Help & Troubleshooting

Hello,
looking for advice on a display issue please. Cracked my Xperia Z screen and ordered a new screen form a shop. After fitting the screen the display shows pixelation/noise on certain images (examples attached).
I have checked the ribbons and connectors and all appear intact and correct.
I would be grateful to know what the causes could be. The shop is refusing to replace saying they checked the screen before it was fitted to my device, saying it must be another issue with the phone. I never had this issue with the original screen.

A couple more pics - when using the xperia system menu display check the last test shows the pixel noise. Reading up a bit it appears it could be linked to the LCD inversion / pixel walk. Does anyone know anything about this on here? Does anyone know if it is likely a hardware fault? There doesn't appear to be any setting I can change on the phone to effect it. Many thanks....

[Q] xperia z1 c6903 digitizer problem

Hello pros,
I have searched this entire forum but no answer, hoping you could help me.
My z1 had some water damage, to make a long story short, here are my issues.
1. Lcd was shot. It was all black Screen.
2. Although screen was all black, i could feel it vibrate and has audible sounds.
3. Touch screen still works. I am able to make and accept calls with or without my smartwatch.
4. With a very bright led flashlight shined upon the screen i am able to see whats on the screen.
5. Bought a new lcd+digitizer with frame and replaced the original one. Followed exact process as youtube vids.
6. Screen now lights up BUT touch screen does NOT work anymore.ggrrrr!
7. Bought another lcd+digitizer with frame thinking i got a faulty one. Same issues. Lcd lights up but no touch feature .
Questions:
1. Is it possible that the flex cable connected to lcd+digitizer is broken? If so, replacing the cable will definitely fix my touch screen issues?
2. Is it possible that it could be a hardware issue? If so, how do i fix it or replace a specific part?
Any and all response is highly appreciated . Thanks

Strange display issues (when cold)

Hey guys,
just a short question, i couldnt find any information about this problem in the world wide web
I've replaced the display of my Z3 Compact. Now i see strange color / lightning issues, when the display is "cold" (e.g. when the phone is idleing on my desk) Additionally, you can see "burned in" Icons from the launcher.
Whenever i heat up the display a little bit, all problems are gone. (perfect light, nice colors + no burned in icons)
Example:
Cold Display:

Warm Display (just 60 seconds under a desk lamp)

I need to say, that I'm quite sure it is no original Sony Display. On the other side.. i dont want to replace it again, because it works when its warm..
Does anybody know, why my display is behaving this way?
Thankyou!

Sorry, I can't help you with your problem, but your red cover looks nice (it's a cover right?). Where could I get one? Thank you.

99% it's a hardware issue that needs to be examined by repair center. I'd recommend you to send the phone for warranty service.

It's not a cover. It's the color of the phone itself, it's mandarin
it looks like this
Looks like the adhesive used to bond the replacement screen to the frame is too thin causing back pressure on the display when cold. Likely non-oem parts were used to replace the screen and they are not to spec.
Yes, it is just a bad GLUE paste

xperia z c6603 dark screen issue

I just did replacement of screen for xperia z c6603, my fault was i did order unbranded non genuine screen. after replacement there is no brightness adjustment possible. no matter what level i try set up its all the time the same very low set. but the strange thing is while im putting the original screen back nothing change while it should, cause before replacement only digitizer didnt work but lcd was really bright not like now. Rebooting, restoring system, updating doesnt work. i think its definitely hardware issue but what?

First ~80 rows of touchscreen not registering.

I'm trying to fix a z3c on which the top ~80 rows of the screen does not register a touch. The screen was cracked so I've tried to connect some new screens.
If I put on one of the el cheapo, unoriginal, knockoff z3c screen replacement I can make touch register on the whole screen.
If I put on a new, uncracked, non broken, original (or very good copy) screen It exhibits the same problem as the original screen I took of, the top ~80 rows does not register.
On all the screens a Synaptics S3528A controller seems to be attached, but who knows if that's to be trusted. I'd like to make the original type screen work since they have better colors, among other things. It is possible that the new original screen is broken exactly in the same way as the one that came on the phone.
Has anyone else experienced some part of the display starting to not register a touch? Is there a way to recalibrate this on a z3c?
Besides broken screens, what could cause the phone to treat the screens differently?

Sony Xperia Z3 E6553 still no display after LCD replacement

Good Day to All,
I have a problem with my Z3+ E6553, the problem is that there is no display on the phone. Couple of weeks ago the lcd just stopped working, the device does come on with the LED lights, vibration and the touch is reponsive with which you can here the touch sounds, haptic feedback and the Speech to text speaking. I thought the LCD screen went dead and so I bought a new LCD screen to replace it but after replacing the screen the problem still presist with no display(black screen). So currently I have no idea what is the cause or what to do next.
I opended the phone was just check some things out, and I had a look at the LCD flex cable and I found something strange that maybe one of the connector antenna prongs missing. But I'm not sure if thats just how it is or its maybe it got damaged. Have a look at the attached pictures below.
Can someone tell me if this issue is with the LCD motherboard flex cable, or another hardware issue maybe being the motherbaord?
