Hello, my laptop screen after power on or moving with lid become slowly grey, with some vertical and horzontal lines, I must find "right" position for lid to get content on screen, but it's getting worse. I must press (and hold) on red rectangle to keep image(when lid is there) Here is photo:
I opened it to try something(pushing cable) but It didn't work
Connect it to an external monitor, make sure the problem is not replicated on the external screen. if it IS replicated on the external screen, it is an issue with your GPU. if it is NOT replicated on the external screen, it's just a hardware issue, either need to replace the screen, video cable, or both.
