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?

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..
A few months ago the screen on my SPV M600 took a knock which cracked it pretty badly, to the point it couldn't be used. I've rebuilt two other HTC phones in the past so felt fairly happy buying and fitting a replacement screen myself, along with the fact Orange wanted well over £100 for repairing it!
I dismantled the phone back to the screen to find it had a gold LCD cable and bought a new one on eBay.
I've now tried fitting the screen which works perfectly when the phone is still appart, but when I put the casing back together the screen goes blank. The exact point it happens is when I'm clipping the side of the phone with the volume control into place. The screen gets very bright as if the backlight is either getting too much power from somewhere or the backlight setting isn't taking effect. If I set the backlight to minimum it's most noticable as it goes from dull to full brightness when I apply pressure between the screen and board on that side of the phone.
I've tried sliding a piece of card between the screen and board to see if there was something touching that shouldn't be, but it doesn't seem to make much difference.
If anyone could offer me any advice on how to solve this I'd appreciate it.
Thanks.
I think I've solved it, I hadn't put a layer of the copper from the back of the old LCD onto the new one. It seems to be working fine now.
OK ordered a replacement screen with digitizer, despite only my digitizer being cracked (surprisingly everything still worked even touching in the damaged half of the screen) as I had read it was far easier to replace the whole screen.
Well I can tell you its still not that easy. After a slow struggle I did manage to swap the screens over, but alas no joy. The phone is probably starting up as there is the usual vibration after release of the power button. The screen backlight is on, but no display.
So now I come to the questions I probably should have asked up front, before ordering.
Are there different models of the screen ie different generations of HD2 have different screens? Is there a way to tell which one the old and new one are? I note that the YouTube video of a screen being replaced shows slightly different internals to mine, thus my suspicions regarding variations of screen.
Lastly would the Telstra Phone version have a different screen from the universal version of the same era?
I will pull it apart again this evening and see if I can see any obvious differences (or install errors) but if there is anyone with knowledge that can guide me as to whether I have the wrong version screen I would be grateful.
Cheers.

Opening up everything again shows both screens have the same HTC part number: 60H00295-DOP and similar serial numbers. So I reinstalled the old display - no change - a blank screen. Checked over all the connectors, ribbon cables, etc all look correct. So reassembled with the new display and performed a Hard Reset. This occurs as expected though with no display. All the buttons work and I hear a peep as the volume is raised up and down. The soft reset button causes the usual restart effect. I also note that back light comes on, stays on for 30 secs, then dims then turns off 30 sec later. I can even tell that the touch part is working as I can feel small vibrations to each touch and if I'm in the volume set screen and I touch where vibrate is I get the usual vibration confirming it has changed to vibrate mode.
It would appear that in the process of changing the display I have damaged the display driver chip or something along those lines as the other processes above tend to indicate the processor is still working and reading button presses, making sounds etc....very sad.
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.
