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.

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?
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.
So this was my first breakdown of a phone...my brother gave me an HD2 with a non-responsive digitizer, everything else seemed to work just fine.
I disassembled it, accidently tearing the flex cable after it gets thin and goes to the volume buttons. Anyway...I replaced the digitizer...thinking I could just modify the volume via software controls, and stupid me had previously set the hd2 to boot into magicdlr always when the phone turned on. So when I turned on the phone I couldn't do anything because it would boot into magicdlr and I had no volume buttons to scroll up and down, and the option selected was boot into windows which was not on the phone (only cm7 was at this time).
Anyway...after getting a replacement flex cable, and reassembling everything, I couldn't get the lcd to work. Backlight would light up, but no picture, no sound, just a vibrate and the backlight turning on. I tore it down, triple checked all the connections, and still the same thing
So I tried a seperate lcd assembly, tripled checked all connections, and still same issue as the above paragraph, backlight but nothing else when I try to power on. I also retried the old flex cable (the one without the volume connector) and that didn't make a difference either.
My only guess is that I messed up the lcd connector on the mainboard, even though it doesn't look visibly damaged in anyway. Does anybody have any other ideas/suggestions?? I would love to get this up and running as its been my first smartphone project...I've done lots of works on desktops and laptops but never smartphones.

Click to expand...
Click to collapse
This is my suspicion too!Even not visible at first sight, try again with a magnifier!
Good luck!
This problem recreates multiple times per day. It seems like the LCD gets powered, but there is no graphics signal.
When I turn on the tablet the LCD Backlight will come on, but there is no graphics on the screen. At this point, I cannot turn the LCD off by using the switch and there is no other action I can take.
I have to wait until the LCD turns itself off (approximately 20 seconds) before attempting to turn it on again. It typically works fine the second time, but not always.
I have called Google and they have issued an RMA, but I am curious if anyone else is experiencing this issue to determine if this is truly an isolated issue.
Thanks.
I began testing with a Bluetooth keyboard and have see the same behavior when waking the tablet up using the keyboard. This would eliminate it being anything to do with the physical power switch.
Hi, i know it's an old issues and few solutions are posted out there, but none worked for me.
symptoms: phone turns on with sound, vibration and top led, menu and back buttons all lit, but screen black, it even responds to touch from the sound it gives.
although, i noticed a way to bring the screen alive for sure is to plug usb cable to to charger then turn it on and screen comes alive.
i don't think it's hardware problem, or flex cable disconnected, because when it turns on it works flawlessly, and as many know dismantling the s5 to check is a real pain.
and if it's a software glitch, is the MM update that's coming out will fix it?
anyone with real knowledge of this issue and ow to fix it, please help!!!
flash stock using odin maybe? idk
