I have an EEE PC here with strange artefacts which come and go intermittently. It has the following 4 states:
2. Distorted as shown in the attached image, distorted part of screen flickers
3. Fine horizontal lines which flicker
4. Completely black
It reacts to movement of the netbook's lid and can always be made distorted or normal by working the lid forward and backwards a little.
I have disassembled the machine and held the screen in my hands, and I could only with difficulty induce any distortions (flicking it back and forth as it would if it were attached to the lid). I reseated the VGA cable both at the motherboard and back of the screen, but it made no difference. The image on an external monitor is perfect, even when the laptop's screen is distorted.
So, I'm presuming that it's either the screen or the VGA cable (maybe getting pinched as the lid is moved back and forth). Has anyone any thoughts?
