I am having problems with my g750jz screen.
It flickrs everytime i move the lid.
I removed the bezel, unscrewed the lcd, remove it then placed it back, returned the bezel, after doing so, the screen worked fine for 10 days without flickering then flickering starts again.
I noticed it also flickers more depending on the color in the background and specially on win 8.1 login screen.
I replaced the screen, still having the same problem.
