Hi, my laptop just started to do this: it start to loose sharpness and gets grey, if i touch it or if i move the screen to a different angle, it resets, but after 1 second starts again becoming like that. It could be the display or the display cable, right? but is there any way can i know that before buying one of the two? Thanks in advance! Before Touching it:

@gabriele_ that is a tough one. Since it does clear up when you move the screen, it appears to be the cable. My suggestion is that you replace the cable first since it is the lesser cost. Then , if that does not fix it, replace the LCD.
