LG G2 screen is flickering and it comes slide? - G2 Q&A, Help & Troubleshooting

Hi, After I opened the screen, the screen comes flickering and sliding. It returns to normal after 5 seconds. I tried it with a different screen, but it happened again. If I disassemble the part that has the speaker, it's getting better.But, If I put it back together it breaks again? What could be the problem? Thanks.

G1 Screen problem

Hello, My G1 has just suffered a problem, i was scrolling down a web page and the screen faded out like it had lost power but the backlight was still on, the keys lit up and it still could make the trackball clicking noise when you moved it. I took out the battery and left it for 5 minutes and rebooted my phone and the screen turned on for about 3 seconds and faded out like before but it did boot into android as I heard the notification/startup sound. I think that the screen has burnt out but im not shore so has anybody had this problem before and/or might know how to fix it
Just some more infomation, If the screen dies and I leave it for a few minutes, when I unlock it or slide the screen up, the screen works for a few seconds but then fades. Also the fading looks like the screen lost power or like its losing pixels
From my experience with phone hardware this doesnt look like screen problem, but rather the lamp driver in the motherboard. the only way to narrow down is test the motherboard /screen with another phone.
If this is the case, it might require servicing the backlight driving circuit, which by far requries soldering/desoldering some components in motherboard.

Samsung Galaxy S4 black screen and responsive to touch and sound

Hello, I am new to the galaxy world and have a question. I have an S4 that turns on and vibrates when powered on. The screen flashes a quick green and then goes black and stays black. It makes noise when the samsung logo comes up. The screen is responsive and all the buttons work. I am curious is to what needs to be replaced or what to try and fix the issue. Is the didgitizer bad or is the whole lcd display bad. I guess any help at this point would be great. Thanks in advance.

I was recently flashing a recovery and at one point I had my battery out and still had my phone plugged in. I look at my phones screen and it is doing this weird flash white static every once in a while thing. Next time i try to start up my phone Boom Black. the only way i found to work around is that i recovered so that it would bring me to the original start up screen where this is an accessability options tab there i was able to turn on screen prompts so it tells me what my finger is on and lets me dbl tap to sect. then with headphones on i spent a day getting it to where i can do h/w testing. still cant figure it out tho

[Q] screen doesn't work after water dmg

So my son got the tablet wet. I let it dry out for a few days then turned it on. Everything seemed fine. It went to home screen but the touchscreen was unresponsive. After about ten second's the screen went negative kinda then blank. It still vibrates and makes noise from notifications and volume buttons. But the screen will not work. Is there a screen replacement I can buy and would that work to fix my problem? If so is there also a video on how to do so? Thank you

Screen replacement, slowly turns white when on

Hi. I had done a successful repair of the screen on my Nokia 6, not to long ago. However my screen was being lifted away from the phone by the case. So the screen was pushed back down back into the phone, and it was lifting again. However I got this weird effect on the screen (attached photo). It seems to fade in white... I can still use and see Android. Any suggestions?
Here is the photo
The screen is broken.
