My brother was out last night and out of nowhere his phone screen went blank. The LCD is displaying the color black but will not show anything else. The touch screen is responsive but you can't see what you're touching. I've tried entering the bootloader and recovery mode, and I'm pretty positive it's working but there is still nothing displayed on the screen. Never heard of this happening to anyone else with the G2. It was running CM 6.1.1 with the original kernel.
Sounds like sumat has come loose. Send it in on the warranty pal.

I have rooted my desire z (about a half year ago) and now I am having a problem.
When I boot my phone my screen stays black during the phase that normally would show that htc logo and white background. And after that colors are weirdly blueish (it goes back to normal after I put my phone to sleep and wake it). Also bootloader is black (I know that it boots to bootloader because when I push vol- and the power it goes to clockworkmod). And clockworkmod is also weirdly blueish. I got this problem when I was trying that unofficial CM9 rom and I have used superwipe, tried several other roms and backups of other roms, but the problem don't go away. Any ideas how to fix this?
It seems that my screen problems change when I open/ close keyboard. So could the cable be a bit broken?
Most probably the cable. If you are still in warranty, take it to be serviced. If not, I'm sure that wouldn't cost much.
Either way, sounds like a hardware problem.
So, recently my One X (EU version, endeavoru) begin showing some problems, as outlined below. It was the newest stable CM (10.3) and a somewhat older version of CWRM. After the problems showed, I managed to upgrade to the latest CWRM and CM. Here's the problem:
- When I tried to unlock my phone, the screen stayed black, so I reset the phone.
- When it started up, the HTC logo looked fine, but the CM logo was shifted down and banded: the top of the circle was visible on the bottom of the screen and the bottom of the circle on top of the screen. After that logo the screen turned black.
- It DID boot though, as I could feel the haptic feedback when trying to unlock, and I could hear the sounds of making a screenshot (power+vol down).
- After some resetting etc I finally got an image of the screen again, and saw that I moved some widgets around, so the touch screen def. works when the screen was black.
- I wanted to make sure it was a hardware problem, so I did a total wipe (factory/dalvik) and flashed a new recovery. This worked, but a few times when working in recovery the image froze. I'm not sure if the recovery crashed and did not respond to input, or that the screen just froze, as CWRM only has visual feedback.
- I managed to install the latest CM, tried it, it worked, and then the screen showed some green lines, and a slight shift upwards (the top rows of the status bar showed at the bottom), and I couldn't do anything anymore as far as I could tell.
- The bootloader also showed some problems: the letters were enlarged and overlapped while the image was also smeared across the screen.
Now, basically my question is: can I be sure this is a hardware problem? HTC will fix it if that's the case, but otherwise I will have to be a bunch of money for nothing, because then they will pin the problem on the custom software/firmware/recovery installed. However, I don't think any of the firm/software can actually influence the bootloader, am I right? So if there are problems with the bootloader, it cannot be the case that something I installed on the phone causes the problem.
i think what u have there is Screen Flickering ,, and it's due to a hardware problem ,,someone had the same problem and he had to replace the screen and the motherboard !!!
again am not sure !!

Thanks! I searched for one x screen flicker and found a video that showcased my problem perfectly:

One of the comments said that if they pressed the screen just below the HTC logo it worked again (temporary), and I could reproduce this on my phone. Now I have no doubt at all it's a hardware issue, and I will contact HTC for repairs!
I'm having a somewhat weird issue with my ACE 2's display. When I turn it on, the screen went blank (not black) but blank, everything still runs but the display isn't showing anything. And by blank I mean the background is kinda like the one in CWM recovery but without the logo. Right now, all i can do to solve this is by removing the battery and turn the phone back on.
I'm hoping someone is also having this problem and have a better solution to it.
PS : My friends say that it's a hardware problem but I don't think so.

What rom are u using ?
I JUST got my LG G2 from sprint less than 4 hours ago and as soon as i got home i rooted it using ioroot25 that i found somewhere online (if its important i can dig up the link but figure its probably irrelevant) and installed TWRP recovery, made a backup, not a single issue, then all of a sudden half hour later i pick it up and turn it on and the screen is mostly white with yellow lines (that move/respond to touch and whats supposed to be going on on the screen) and it will not show any sort of picture just kinda yellow fuzz lines...it looks just like some phones ive seen with cracked/ faulty LCDs but if i hold the power button and up or down to hard reset it, the LCD starts working again upon boot, and continues to work untill the LCD turns off for the first time after booting and i try to wake the phone again, every time i turn the screen on when its on it goes back to fuzzy lines with no way to make it start working other than restarting the phone with the buttons on the back.
anybody ever seen anything like this before? it cant be a broken or cracked lcd cuz when it first boots it shows a crystal clear screen and everything works fine untill the first time the screen turns off...im guessing i am more than likely going to end up making a trip back out to the sprint store tomorrow for a manufacturer defect replacement? any insight into this strange problem would be greatly appreciated!

Faced similar problem with LS980
I am also facing similar problem with LS980.
Only additional mistake i have made is -
I have installed TWRP recovery for D802 instead of LS980(Seller labeled it as D802). After reboot into recovery mode, My lcd showing only lines.
Any suggestion/help ?
Hi,
I installed the cyanogenmod 11 nightly like a week ago on my galaxy note 2 and all was running perfectly until this morning.
When I woke up this morning the phone screen was black. The phone is actually working, I can hear emails notifications, phone ringing etc.
The buttons light up when i press them. When I connect it to the PC I can browse the phone contents etc. All seems to function except the screen.
The battery is charged. I tried to remove the battery for a long time and try again but still nothing.
I can't get into recovery or download mode as the screen is blank (sometimes there is a like a weird area at the top where there are like different colored pixels present). I know people will say the screen might be damaged but last night before I went to bed it was all fine, the phone was placed on the table, and this morning when I picked it up screen is blank.
I want to flash back the stock firmware. However I can't get into download mode in order to use Odin. Is there any other way to get into download mode or hardware reset the phone?
Any suggestions are welcomed.
EDIT: The touch screen also seems to work when I touch it as I can for example call numbers for which I had speeddial scortcuts but it is still completely blank.
I think this is hardware issue. You must replace the screen

Yeah I think so too. I've sent it to Samsung.
It was rooted and had cyanogenmode so probably I have no warranty
However I managed to install stock ROM so hopefully they won't (can't) notice.
