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?

yeah, if you connect the flex very well but the screen didn't work, you should do replacement.
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
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

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?
Hi guys . I have an xperia z phone that had a bad usb port so I ordered the part since it's not soldered to the board. I put the phone on my picnic table until the sun warmed it up and took the back off. I removed the old usb and replaced the usb connector. But now the phone led comes on when I charge it and also it vibrate so I checked with a brite light and there is a picture but no baclight. I didn't think I did anything wrong while replacing the usb. What could I have done wrong? And is there a way to fix this? I don't thing replacing the screen will do anything since I didn't even touch anything near there.
