My daughter's device has been having all sorts of problems. Her backlight stopped working so I replaced the Digitizer and the LCD screen but that didn't help at all. The calibration doesn't work and the screen won't rotate. In addition, her headphone jack is on the blink as well. Do I need to replace the motherboard flex cable or is there something else going on? The ambient light sensor seems to be on the fritz as well which might explain the backlight not working. The phone is using stock Android. Thanks for all and any help.

i have the wizard and the screen broke the LCD display is intact no bleeding and displays everything fine but the backlight doesn't work...Do i just replace the touchscreen or the whole LCD unit for the backlight to work?
Are you sure?
Are you sure the backlight is broken? There have been several software conflicts that turn the backlight off.
Otherwise I don't know, but there is an HTC disassembly manual on the board somewhere.
no i checked everything and the backlight was working before the touchscreen broke and stopped right after....does the touchscreen have anything to do with the backlight?
My buds Droid 2 back light doesn't work anymore as well as the touch screen digitizer. Is the back light in the LCD itself or is that a seperate part? I told him I would fix it and I need to know what to order.
I'm having a similar issue, My wife got the phone wet, so we dried it out. That part went well....
Well she got a new phone, and I put the Droid 2 in a draw, and recently found it again, deciding to look it over, I charged it up, turn it on.
Here is what problems it has, No Backlight on the LCD display, No LED Nofication lights, No keyboard lights, No Digitizer touch.
The phone boots and works, sounds work, OS is intact and under a flashlight I can see the screen.
my question is does the ribbon cable control all of these? or are the seperate problems?
My Atrix's screen randomly stopped displaying anything. You can see that the backlight turns on and off but nothing ever displays. The screen isn't physically damaged and the touch sensor is also functioning just fine. If I plug it into my Lapdock - I can use the phone with no issues, I'll just never get any sort of display on the cellphone's screen (Outputs to Lapdock's screen just fine).
Any ideas or suggestions?
are you able to adjust screen settings when you're on lapdock? (and does this change anything?)
It does sound a hardware issue with your screen... maybe others on here can offer more help
Just tried playing around with the settings - no luck
Do you think maybe the display cable somehow disconnected? I'm not sure how the Atrix is designed but I think you'd normally have a separate cable for backlight, touch, and display. Maybe I'll try disassembling it and report back.
Hello!
Yesterday, my LG G2 D800 had a backlight issue. I was able to use my phone in direct light and utilize the touch screen in its entirety at the time.
I took off the back cover and reconnected the Backlight cable to the motherboard, and that solved my issue regarding that. However, after the fix, my touch screen no longer recognizes inputs, even in Recovery Mode (TWRP, so it needs touch functionality).
I tried to disconnect & reconnect all cables on my motherboard, but my touch screen still does not recognize inputs at all.
What could have caused this? I took off the back cover gently with a plastic spudge, and only removed the bottom motherboard cover that had the backlight cable attached.
tldr
1) Backlight stopped working, but touch worked
2) Re-connected backlight cable. Backlight works, touch does not work
3) Reconnected all motherboard cables. Backlight works, touch does not work
Any help would be appreciated!

i recently replaced the lcd and also have the same issue. It detected that my screen is covered so i can't hang on a call because the screen wont turn on.
but suddenly it works when i cleanup the screen with a damp cloth. but sometimes it doesnt work.
I know this thread is super old, but before I start a new one on exactly this - I had to disassemble my phone to replace the audio jack, and since then, my proximity sensor won't work at all. I double checked the flex cable and plug, tested the sensor outside the phone, still nothing. It ONLY works if I put sth white or metal-like exactly 2 mm away from the screen, no nearer, no further. Its super strange and annoying. Was anybody able to solve this?
Edit: LED and ambient light sensor (which is exactly the same sensor) are working! And before the sensor stopped working I did not even touch it at all!
