Sometimes the pins in the LCD socket can lead to this behaviour, are all pins in place?? If so, I would advice you to contact the seller to send a replacement.

I tried another screen from a friend of mine. It didn't work either. So obviously, the problem is on the phone board (black screen when power on the phone.)
Is it possible to change the board? Do you think it works?

Changing the board will work, so long as the board hasn't been bricked or otherwise rendered non-functional.

After changing the board, imei number will change too. If so, is it possible to transfer the imei number too?

In the US at least, changing the IMEI is illegal. I'm pretty sure other countries frown on the idea, since the IMEI is essentially the device's fingerprint. The Dell service code can't be changed either, but that's only because of a hardware limitation rather than legality.

[Q] Streak 5 not displaying anything

So, being clumsy, I left my Streak in my hoodie pocket. Well, we can all see where this would end badly once I bent down to pick something up. I did, dropped my phone and cracked the screen.
I quickly went and bought a replacement glass + lcd display, and replaced the unit. But, upon turning the phone on, I noticed if I hit it a little too hard on one corner, It would restart, and the vibrator motor had ceased to work.
So I figured, hey, I'll just rebuild it again. So I took it apart. Looked through everything, took my time in putting it back together, because maybe everything wasn't fitting snug.
Now, When I turn it on, every thing is on, buttons light up, and the screen is lit up, but it is black. I never even get to the Dell logo. After about a minute the buttons dim, as if in idle. So i believe the phone still works, but maybe the connections on the MoBo is faulty? Any help would be nice, thanks.
check to see if the ribbons are snugged in place.

Well, I just took off the rear cover and reseated all 3 connections, pushed em in as smoothly and far as they would go. But, same thing. Black screen. But the LED is still working...
I'm having the very same problem. This is my second replacement screen and neither displays anything except black screen with backlight on, and the home + settings + back buttons remain lit. I can hear my phone starting up and receiving messages, but I cannot see anything. I've taken the phone apart and put back together five times between two replacement screens.
Does anyone know what ribbon cable might be at fault for this particular issue? The largest ribbon cable was shipped bent across the circuit board on both screens; there is a permanent creese in both ribbon cables, but I'm not certain this is causing the issue.
Any insight or assistance with this issue would be greatly appreciated!

Blank screen, only backlight ON

Hello everyone.
I have a problem with my smartphone Sony Xperia Z2. I dropped it and the display broke. I bought a new display. When I connect he went crazy. He began to open the application, clicking like 10 fingers working on it simultaneously. Because I thought that the display is faulty, I've exchanged for a new one. But now even bigger problem. When I turn on him, he does not show anything on the screen except the backlight. Do you know what the problem is and whether anyone had a similar problem? So, when the smartphone turns on, lights up only the backlight but nothing on the screen showing a. At first, there is a lot of vertical lines on display, and once he just fade out, and from that moment display is blank only backlight working. I try to update software, but nothing change. Restarting, and turning off also nothing.
Please help me solve this, for me very frustrating problem.
anyone?

Did you ever get this resolved?
I had this issue after a screen replacement for a shattered screen. I was sure I had damaged something in the process (ribbon flex cable, motherboard, etc). Turns out the replacement screen was faulty. A new working screen solved the issue.

Changed digitizer, LCD doesn't work

Hey guys,
I am not sure if this is the right forum to ask, I am desperate and I need your help.
My navigation buttons started to push itself, so I disassembled my phone (gently of course)
I found out that the digitizer flat cable is torn like.. 3/4 of its width so that was probably the problem.
I ordered a new digitizer and it arrived yesterday, so I put everything together, started the phone and the LCD doesn't work.
When I start the phone it vibrates as usually, then the LCD screen turns on for couple of milliseconds so I can just barely see the HTC logo and then it turns black, the navigation buttons are lit and I've heard notifications after I let it run for 30 seconds.
What could be the problem? I checked multiple times if all the flat cables are plugged in correctly. It's weird that the LCD runs for couple of ms and then it turns black.
Thanks a lot for your answer,
Adam K.
How bright does the LCD get? It is possible the lighting element went bad.
It gets bright as usually, but just for half a second, then there's just black screen.

No LCD, just backlight

Hi,
Trying to fix a Z2 for a friend. She dropped it, smashed the screen. You could still see the LCD, but the digitizer was fubar. Ordered a new screen assembly, but after the replacement only the LED backlights work - no LCD at all. To test, I reinstalled what was left of the old screen, and no LCD, just backlight, so I don't think it's the new screen. So then I ordered a new main ribbon cable and replaced it. Same result: no LCD, just backlight. You can hear the phone on when it's on, the phone "responds" when you touch the screen, you just can't see anything. I upgraded to the latest software update tonight using PC Companion, but no change.
So, the only thing left is the motherboard, right? I know there is a fuse on the motherboard that, when it fails, it kills the backlight and leaves you with only the LCD. I have the opposite problem. I'm hoping maybe there is something like that for the LCD??
Thanks in advance,
Heath
I have same issues with you and also try ten new lcd all show backlight only..what your solution??
Have you tried to connect it via a MHL cable to TV ?

Touchscreen ghost touches(screen flickering)

Hey guys, recently I had my Z2 sent to a service shop because it wasn't turning on or charging. The guy at the shop said that it was the battery fault and he changed it, but he also told me that the screen was not working( flickering, ghost touches, unable to work on it). So he put my old battery on and when I went home the phone actually turned on and booted up, but still I had the screen problem. So whenever I touch the screen it doesn't respond and it touches by itself. Tried putting it on rice for 20 hours, dried with a hairdryer and assembled dissamssebled the screen jacks, still the problems wasn't fix. Do I really need to change the whole LCD or is this a problem that can be fixed?

Yes, you have to change the screen, or more precisely, the digitializer.
But since the LCD and the digitialier come in one-piece, you have to change it as a whole, but at a much lower price, as your screen can be sold again and recycle the good LCD panel.

So replacing the LCD would fix the problem right? That's great then because I found an LCD with a very low price (20$), completely new on ebay and I sucessfuly dissassembled the old LCD out of the phone. I'm gonna buy it as soon as possible. Thanks man.
