Eonon Ga1312 and screen off - MTCB Android Head Units Q&A

I have got this device and since days ago I've been noticing an issue.
The screen doesn't show anything and it's full black.
If you close or open the screen you can see the output signal on the screen during the movement when the screen is positioned horizontal.
But it just positions in vertical you can't see anything.
If you try to touch the screen you can notice that the touchscreen works well.
I installed Malaysk's February rom and if you try to go in Recovery you can't do it!
The screen remains all black.
Do you know how can I fix it?

[Q] Screen Issues: Static Screen Vertical Lines Right Before Lock Screen

When I wake the phone, seconds right before the lock screen I notice a type of static screen with vertical lines.
It is more apparent when trying to wake the phone in dark settings or a dark room.
Stock Phone, No Modifications.
Is this normal? Has anyone else noticed this on their Epic 4G Touch? I just got the phone 3 days ago and am wondering if its a hardware issue and if I should return it. Any help is appreciated.
Attached is a picture that resembles the pattern.
I've never noticed it. I even tried to re-create the issue and I couldn't. I am also running the stock firmware (EG30) and I am not rooted.
Thanks for the help... I'm not taking any chances. Called to get a replacement.

[Q] Horizontal lines: hardware defect?

All of a sudden my screen looks like an old interlaced CRT. Fine print looks jagged and I can see an irregular pattern of horizontal fine lines, especially on a white background. Those lines do not turn with screen rotation.
I rebooted several times with no effect. The lines appear on the recovery screen, as well.
I should mention that my phone dropped on a tiled kitchen floor this morning, but the lines only appeared at noon. Everything else works fine.
Has anybody had this problem and managed to get rid of it?
Got it repaired under warranty.

[Q] Screen not turning on after touchscreen test

A few months ago, I broke the screen on my nexus 7. Recently, I decided to replace the screen. I bought a screen and put it in uneventfully, but I noticed that there was a diagonal stripe on the screen that didn't respond to touch. I knew that nexus 7s have touchscreen issues, so I downloaded the app Nexus 7 II Tester. One of the patterns caused the touchscreen to not return to normal after closing the app, so I restarted the tablet to try to fix it. However, after turning off, the screen would not come back on. The backlight is off. According to getevent from within adb, some touch input is getting through, but when I look at the screen through Android Screen Monitor, the touch input seems to be erratic. Aside from issues with the screen and touchscreen, the device seems to function normally.

[Q] screen flickering

Hi guys,
anyone had an issue where the screen flickers really badly? Mine has been working great then today it did a weird glitch where the button bar at the bottom went halfway up the screen, and the screen flickered really bad, like a tube light starting up. Ive reset it and now its flickering like a fluorescent tube light. everything still works, but im on the phone to three now organising to get it returned.
cheers
Ray
ok, so an update to this. after leaving the phone on all day the flickering screen stopped flickering, however now i have an issue where plugging my ear pollution headphones causes the phone to now show as a headset with microphone, and the voice assistant to appear. It is also now getting really hot on charging where it didnt before, so my returns envelope arrived today, and its off back to LG for a repair. Seems very strange how its happened after a month of relatively light use, where my 2 htc phones were working great after 2 years of use?
anyway, lets see what rubbish comes back from LG
Home screen Magnifies
I have a weird problem with LG G3 screen
When i double tap to lock the screen .....Home screen Magnifies and if i double tap on that again it goes back to normal
I dont understand why .....can anyone please suggest me if any option to be tweaked under settings
Thanks

[Q] Sometimes several lines appear in the bottom of screen

I have problem with my beloved phone. Sometimes there are several horizontal lines appear in the bottom of screen and disappear after being locked - unlocked. Is that a bug of firmware/ROM? I used Revo 5 and now using Carbon 4.4.4 n the anoyying line still appeare sometimes. Maybe the problem is recovery or anything like that..
Anyone knows how to solve it??
Defective LCD
Try to replace a brand new LCD buddy, the lines that appear is a sign that your LCD is not in good condition, however you can still use your phone for several period of time.
