This is a problem with a screen of a laptop. It's something related with a broken wires in the junction between the computer and the lid because my webcam, that is on the lid too, sometimes it leave working when I touch on the lid.
Does anyone know what it is?
I recorded a video reporting the problem: http://www.youtube.com/watch?v=IipyFT422Hc
At the beginning we can see the image flickering and then when I change the image by changing the windows. In the end, we see a CRT monitor connected to laptop running well.
The warranty is no longer available.
It's a Insys M761SU, a detailed description can be found here: http://rigon.me/insys_m761su.html
