My current Dell Streak 5 dropped and the screen was cracked. I bought a new LCD screen from China. and replaced it today. But when I turn on the device, the screen backlight turns on, But the whole screen is Black...
I tried 3-4 times to re-plug the sockets and connectors. I believe I did all necessary things to solve this Black Screen problem out, but couldnt achieve.
Can anyone suggest me what to do? As I said,
when I turn the device on,
- button leds are lighted,
- backlight is lighted,
- but the LCD screen is black (no visualization)
Waiting for your suggestions...
Peace,

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?
sent from my LG-P895.
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.
Hi!
My one month old S6 Edge fell down last week and the front glass broke. However I used the phone normally until today when I got the display replaced in a store. With an original out of the box display from Samsung. After that I noticed that the back and app key (the lowest touch buttons one the front) did not light up at all, although they did work. When I put the phone in the flip wallet cover it went dark and did not respond anymore. I could here it getting emails or phone calls but the screen kept black. I pushed Volume Down and Off buttons until it restarted, with normal screen (the touch buttons also lit up for a second) but after loading normally the screen went black again. If I took it out of the wallet cover it lit up, the two keys also lit up, but the keys did not work at all. Again forced restart. Without the wallet cover the phone starts normally and works except that the touch buttons stay black, but they work. The moment I insert it into the cover it goes black.
It must have something to do with the magnet sensor?!
I took it back to the store, the guy put back the brocken screen and it acted again the same. Then he ordered the USB Board (the part with the charging port) just in case he may have broken it himself but actually he doesn't know if that will help.
Do you have any idea??
Thanks!
My phone was working fine when I went to bed last night. I laid it on my night stand and this morning I noticed I couldn't get the screen to light up. The blue LED was blinking like I had messages. The Menu and Back buttons light up when I press them, and I can even hear when someone is calling me, but because the screen will not light up, I can't answer. The phone screen is in near perfect condition, not a scratch or crack on it and I also have a cheap protective screen over it.
Hoping it was just a glitch, I removed the battery and held the power button for about 45 seconds and powered it back on. Same thing, black screen during the entire boot process, no logos or anything. I also tried to boot it in safe mode with same results. There is only one time that the screen shows any signs of life and it only happens when I first power it on. In the top left corner for a split second, where the usual "Bootloader is unlocked" message appears, it displays a small rectangle of colored artifacts inside that small message area.
I assume the LCD went out, but I'm concerned it could also be related to the GPU or other hardware, and so don't want to spend a lot of money buying a LCD if it's something else. I can still connect it to the PC, so I'm hoping someone knows how I can test the hardware from the PC, or at least recommend something. Right now the phone is ringing and I have no idea who it is...this sucks!

Hi there - I am wondering if I can get some help here.
I had an old working HTC Evo 3D and I use it as a spare phone during travel to use prepaid SIM cards. I wanted to change the complete housing of Evo 3d and purchased a front, middle & back frame from online OEM vendors. As a newbie, I was so excited and started to disassemble the phone and to put into the new housing. All went well till I started to take the LCD and digitizer from the old housing. I made a mistake and ripped the flex cable of the digitizer. I felt very bad and then I decided that I need to order a new digitizer online.
I continued to reassemble the phone with the new housing till I receive my new digitizer. I made sure that I kept the sticky tape in the front housing intact so its easy to take it again. I completed the assembling and when I turned on the phone the LCD was displaying white and black dots like grains. However, I could hear the HTC boot sound the “Quietly Brilliant” sound. At this point, I thought I have damaged the LCD too.
Today, I tired to switch again, I dont see the phone booting-up or hear the boot-up sound or see the white and black grain screen. When I charge the phone, I see the red LED light and then after some time it turns green. I tried all type of resets like power+volume buttons, power+camera button, long press power button. However, I dont think anything is happening.
Now, I am worried if the problem is now with the display or I damaged the motherboard. Does anyone know if the phone wont start if there is a damage to the LCD/digitzer? I am just waiting to know what might be the problem before ordering LCD/digitizer. I am unable to check which part is damaged now.
Thanks in advance!
Hello XDA.
The screen on my LG G3 Verizon (vs985) has been acting weird and I really would like a second opinion about if I have a screen issue on my hands or if it is a motherboard problem. I included pictures below.
Screen responds to double-tap-to-wake, and buttons still work. I'm able to turn phone off by pressing power button (as long as it normally takes to display Power Menu), then tapping on where the Switch Off button ought to have been displayed. Apparently, motherboard sends stuff to screen, but screen unable to visibly display it.
I've been using motherboard since it was bought new 6 months ago so I really doubt it's the motherboard, but I could be wrong. Screen is over 4 years old. The best way would have been to try another trusted motherboard (if screen is still not normal, then it's DEFINITELY screen's fault). So in the absence of such a conclusive test, I would appreciate opinions.
Thanks.

SOLUTION: It turned out to be a screen problem (screen was replaced and voila!).
