I just connect the new lcd/screen to Z3c, but it doesn't work... It's 2nd screen. No LCD and backlight... Damaged motherboard?
I can connect phone to Flashtool (blue, green LEDs)
Could be that the firmware is damaged.. maybe try reflash your firmware - if that doesn't work it will probably just be the screen is screwing up
Replace this capacitor or just make jumper on it.

Hey
A friend of mine called me yesterday if I wanna buy his broken X1 (it felt down :/) and repair it, because I'm the man for such jobs
Do you think it's only the LCD-flex-cable or another repairable damage?
I think I can get that device for 2-3 days and then decide if I buy it...
Some ideas? Is there any chance to repair it?
Thanx, Carbon
yes, probably even a loose connector on flex cable
Hello,
I am quite certain it is an easy problem, i have seen many x1 phones with just a minor loose connector which causes the screen not to respond.
The best way to check it if it really is just the screen/flex cable is to turn it on, and check if the side lights flash in all colors.
If that works the phone should work normally. (even if the screen doesn't work)
After opening:
Re-insert all the cables in the screen flex cable and check if it works..
if that doesn't work then replace the flex cable.
If the screen works:
Then check out the screen if it has any crack's or black spots.
In that case you will have to replace the screen/touch screen also.
Generally, if there is no physical damage to the LCD itself and the phone buzzes on startup with all appropriate sounds - replace the flex. Flashing lights are attached to the flex and are positioned ABOVE the LCD on flex connection, therefore will not light up if the flex is damaged and neither will the upper keypad and other less obvious things.
The flex replacement is not minor, just be aware of that. Bad falls are also the reason for main PCB damage, in which case there will be nothing you can do.
Thank you so much
It was a "very short" call by this friend, but when i take the device, I want a precise report what happened...
atm I don't now if the sidelights show reaction, but I will report
I'm afraid of a real PCB damage...
In flex problem side lights will not light up, as i mentioned, they are positioned above the Lcd connection, so if the main flex connection ribbon is damaged, as is most often the case, all of the upper level functions will be gone, but you will get a startup with buzz and sounds present.
I got it
And LEDs are flashing and you can start it complete normally, but you see nothing... i'm going to open it and check the Flexcable

The Lcd is a very simple device, it's either working or not much like a pc monitor. If you properly reconnected it to the mobo it should display an image regardless of whether the digitizer is working or even on the phone. Take the back cover off and recheck the connection. You can also check the connection with a magnifying glass to see if you bent a pin. If you still don't have a visible screen then most likely you damage the lcd when removing the digitizer strap.
tnx

find new LCD. Had replaced it. Everything woke good. Thanks alot.
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?
Was trying to fix my phone, but messed it up even worse. I snapped the cable that connects the screen to the motherboard (that cable that goes through a slot). Is that the digitizer?

That's the LCD connector. If you've mangled that cable beyond all doubt, then you need to replace the LCD. The Digitizer connects somewhere separately and is a lot smaller.
Hello guys, Yesterday i changed the battery on my phone. After putting everything back together my screen stopped working, with no image and no touch function. The cable on the right bottom is connected but perhaps i damaged it in some way..
The phone is working properly, if I connect it to an HDMI it works.
Any ideas on what I may have done wrong and the solution?
I took it to a shoo and they say I have to replace the whole screen (USD 100 approx) which seems too much..
Check this coil. If it's shorted it's ok, if not make jumper on it. Also check filter (small bricks) under the LCD flex connector and LCD flex itself if it's not teared. Those are common damages which can be done disassembling this phone.
Yup it's the LCD flex that is dammaged.. Is it possible to repair? I'm guessing that on a shop they will want to change the whole LCD screen..
Unfortunately there is no way to change flex only. If it's damaged You have to change whole screen.
Ok, oh well that's life... thanks for the help though!
