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?

I just replaced my old broken LCD screen for the mda and installed the new one. The screen works and so does the touch screen but there is no backlight and settings are on for backlight... Whats wrong??? Please help..
I haven't opened the MDA so I'm not sure what the cabling is like (to know if it is a separate cable that controls the backlight or not, if so then this might be inaccurate)...
Sounds to me like the LCD has a dead backlight. Was it purchased used or new? and where from? meaning was the dealer reputable. If so, contact the dealer and ask them for a replacement. As, at least on laptops and most (though not all) electronics, the backlight is integrated into the LCD housing and sold as a single unit. So a failure of the backlight, though replaceable, usually results in the replacement of the screen as a whole.
The LCD was purchased new and came in packaging and had the plastic still on touch screen. Purchased it online. The screen works fine its just the backlight. you might be right about the dead backlight I'll contact dealer and tell them. Thanks
MDA Backlight issue
I ran across a problem with the MDA, where I adjusted the Backlight settings. From there on the Backlight woulf not turn on unless I went to the setting control to adjust it. The fix: Go to backlight settings, set your brightness desired (maybe in the middle). Go to Battery power from the tabs that are currently listed. Make sure you have (Turn on Backlight when a button is pressed or the screen is tapped) Selected. Then press ok.
That should fix it if the issue you are experiencing is similar to mine.
i tried the settings and no good..Is there anything else I should try? Please help.
tried these settings and no good...is there anything else i can do please help..
I am currently in discussions with the screen's vendor about the issue, but I figure somebody might have some advice to offer here too. I purchased a replacement screen for my Vogue after I cracked the factory LCD. Touch membrane was fine.
Opened the phone, pulled out the old LCD, replaced with new one, etc. At first, the "new" screen seemed to not power on at all - then after several cycles of open phone/test connections with old LCD/rebuild with new LCD I finally got the backlight on, yet the display itself seems to not be working. There is an ever so slight greenish glow in the bottom left corner of the replacement screen when the backlight was on.
Several hours later, during which time the phone just sat on my desk idle (but on) I hit the power button to turn on the screen and was dismayed that the backlight did not come on (simmilarly to how it was originally.) I am certain the phone was assembled correctly, all connections are secure, etc.
The vendor suggested adjusting brightness/contrast settings, which I skeptically tried to no avail with MyMobiler. So at this point, the backlight seems to work when it wants to and the display seems to not work well at all.
Has anyone else seen anything like this?
Hi all,
I noticed there were a few threads about brightness being stuck on the lowest setting after LCD replacement, but that's not my issue. So here goes...
I replaced the LCD and touchscreen on my DZ with ones I got on Ebay. The touchscreen is from a G2 and seems darker than the old HTC - I can't as easily make out the brightness sensor on the front as I used to.
After reassembling the phone and reflashing my rom, I notice that the brightness sensor isnt working. Is this a consequence of the glass over the sensor not having a cutout, or being too dark? Or is it that I need to set a different configuration as my phone now has a G2 touchscreen? Or is it something else completely?
All other phone functions including the proximity sensor are working.
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.
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!
