My LG G3 D855 appears dead. Without any apparent reason the screen turned black upon using the phone, and afterwards the phone did not boot to the OS, which has been updated to Lineage few months before.
Upon booting the LG logo might appear, and then the screen becomes black or blank. Even getting the LG logo to appear is difficult, usually nothing happens when booting the phone or replacing the battery. I have tried two different batteries.
I have three different screens. I have tried replacing the screen and the same problem persists, although in these cases the screen may also turn white. However, this may only be because of the screens. One I haven't tested before, and a other one is an old screen that was not in good condition.
What can be done to troubleshoot the black screen issue?
I managed to get into the (custom) recovery.
Anything in particular that should be done?

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!
Hello. My G3 has a really annoying and serious issue. It simply is turning off at random moments and booting into a boot loop. Say I am typing a text or watching a video, BOOM. It shuts off, as soon as it's off it boots back up into the FIRST lg boot screen (before the animated boot logo on any rom) if I am lucky it gets past this and into the animated screen. But usually it boots into this screen, shuts off, boots into this screen, shuts off about 16 times before, maybe, just maybe booting up. But it qill even shut off on the animated screen too. It sometimes takes a good 15 minutes to get it to finally boot. (Almost like a car not starting). I have tried multiple wipes and reflashes of the stock KDZ. Nothing is fixing it. I am certain it is a hardware issue, but more specifically the battery. Any input? Thanks!
Here is a video to show what I am explaining, it can happen anywhere at any time.

Certainly does sound like hardware issue if after flashing stock kdz and doing the necessary wipes, out of curiosity does your phone get very hot at all. I mean it could possibly be the battery, have you noticed it draining very quickly or not charging correctly?

Nope. Battery life is as it always has been and the phone isn't overheating. I am very confused haha

Forgot to mention. Every time this happens, the lock screen wallpaper gets reset to stock. Seems like some kind of forced power cycle which ends up wiping data.

My LG G3 froze the other day and showed a blue screen and restarted, then another blue screen after restart, then it just keeps freezing and blue screens on occasion and then restarts and so on basically my phone does not work after about 3 minutes of usage unless its cold which I find bizarre, anyway if anybody can help me if this is repairable I would be very grateful I have attached an image of my first error message out of the amount of times I have tried to get my phone working.
I have flashed multiple kdzs including the orginal and this has not fixed the problem.
Hi, so a week ago I had this weird problem with my phone. It would just freeze for like 2 minutes, work again for a minute and so on.
Did a hard reset, same problem.
Flashed that 6.0 KDZ, no success. The phone started but I was basically stuck at the lock screen, touchscreen was unresponsive, power menu kept showing up for no reason... couldn't even turn the phone off.
After that, I decided to stop ****ing around with it and send it to a repair store (no warranty). Today, after about 5 days, I picked it up and was told that they tried a ton of ROMs but they have no idea what's wrong with it.
Got home, ran a hard reset again and now I can't even get to the lock screen, phone is basically in a boot loop. LG logo shows up, the "Android is starting... Optimising apps" screen does its thing, restarts and keeps going like this forever.
Is there anything I can do or should I just throw the phone in the garbage and get another one? Any suggestion is appreciated, thanks!
Hi,
Same issue for 2 days...
My G3 was suddently slow and unresponsive so I removed the battery.
I put it back again, as usual, and start the phone. But it get stuck at the LG logo.
Sometimes the animated LG logo shows up, sometimes not.
Sometimes it displays the PIN screen (unresponsive or not), sometimes not.
Sometimes it boots totaly normaly (1% of time) and become unresponsive/buggy after a couple of minutes.
I tried flashing kdz (normal and CSE) 10 times, factory reset, change battery, without success...
Good luck.
