Hi I recently dropped my T-Mobile HD2 in a puddle of water very briefly i took the cover off and battery right after it happened and wiped everything down. The phone worked flawlessly for about 6 hours then I finally got a black screen. The phone will turn on boot into android(2.3 NAND) and the touch screen works plus im able to recieve calls and messages BUT the only way to tell is to use a bright flashlight to see the screen as I have NO BACKLIGHT. Help me please?
You have probably dead light emission layer. By all means, LCD is to be replaced.
You shouldn't turn phone on immediately after accident. Removing battery immediately, complete disassemble of every possible piece and letting it rest for 2-3 days in warm dry place is a proper way to do this. Next time of course.
So just replace the LCD? Should I order a digitizer with it? Thanks in advance.

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!
so after dropping the thing in the pool and doing the rice trick for a few days the phone seems fully functional except the screen shows nothing. Normal startup and shut down noises, bottom keys light up, touch screen functions because I can unlock it, etc. anybody know if there is a fix?
Nope.

Yes replace the LCD, claim insurance or send it t-mobile or buy a new one
My wife dropped her S3 and broke part of her digitizer so I knew I had to replace it. I found one on ebay and it was delivered days later. First thing was hooking the screen up for testing before pulling the phone completely apart. With screen attached the phone boots up success the touch screen works. I shut the phone down, pull it apart, remove broken screen, attach new screen and reassemble...Phone boots and looks great but now the touch screen doesn't respond!!!
WTF is going on?! I tested the thing before hand. Used a hair dryer so there wasn't any excess heat and used kitten gloves during assembly.
Any idea what I can do to get the touch screen to start working again?
TLR - Tested digitizer before installing after installation complete touch screen doesn't work.
the only possible answer you're gonna get is that you did something wrong. and there's no way for us to know what. so try again
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.
Hello!
My phone fell from a high place some weeks ago and the screen shattered. Touch was unresponsive, clicking everywehere, but LCD was fine, i could see everything on screen normally.
Ordered a new screen. Changed it, but when I turned it on, only backlight of the LCD was visible, but it was displaying nothing. I thought it was a defective screen (either way, it was, lots of stuck pixels), sent it back and bought another from the same seller. When I changed it and turned it on, again, no video output, lcd would light on but woundn't display nothing on screen. Googled a bit, found out it could be a defective fuse on the motherboard, and that soldering it again would solve. I know nothing about this kind of stuff, so I picked up a tweezers and apllied a little force on every fuse, because I thougth that way I could try to solve it. Well, it worked, kinda. I put the screen above that blue plastic glue only for testing, and it worked, I felt reliefed for seeing sony boot logo again. Figuring out it had worked, i took out the screen, took out the blue plastic, and glued the screen back on. For my surprise, it had the same problem as before, and it doesn't matter what I do now, it wont work anymore, only displays a black backlight with no video.
Could anyone help me out with this? Give me a hint of why it worked once but not anymore. Could it be there's really a defective fuse, or it was just a coincidence that it worked after it had force apllied? Also, the Screen flex is kinda loose, it keeps coming off all the time, and it's really hard to plug it to the LCD sometimes, is it supposed to be like that, or could it be the culprit? Also, touch is working normally, i can't see nothing on screen but i can click and feel it vibrating.
It's kind of a big text, but that's the way I could explain it. Sorry for the bad english, it's not my native language.
And thanks in advance if anyone can help!
