Help LG G2 screen problem

[exploder2013]

Hello, androidforums users. Recently out of nowhere my LG G2 has been acting up. The screen started to flicker out of nowhere. The weird thing is, after some time, it fixed itself and I could use the phone again without problems, that happened about 3 times. I assume that's now the screen problem because the touchscreen is working fine and if the problem has fixed itself in the past and screen worked perfectly after that. Just now I opened up the phone, disconnected all the cables, reconnected them and it is still is this broken state, so it couldn't be any loose cables. I have replaced screen for this phone twice, so it's not original one if that helps.

Any user has been experiencing something similar? Is there any ghetto solutions anyone can recommend trying before bringing phone to repair center?

Update: sent it to repair center to see what the problem was. It was actually LCD screen, it's cracked a little bit or something. By pressing hard on my screen, I can fix the problem for some time, but best solution would be just to buy a new screen on Ebay and replace it.
