Display Problems, Green and white lines across screen Options

[totaln00b]

Hi All,

My partner has a 760 that he doesn't use all that often (shame on him) so he often has to charge it up before use. Last night he switched it on after charging it all day, and as it booted up (cacko 1.23) it had strange green spiky lines going up from the hinge edge of the screen. They weren't static, but got longer and shorter, like earthquake seismographs.

When the system finished booting and got onto the splash screen, the lines had gone but the display was very washed out. When cacko was fully loaded, the display was washed out and the lines reappeared, but in white this time. It also seemed as if the icons on the desktop had lines coming off them as well.

Taking out the battery and rebooting didn't help. The japanese menus seemed to be washed out as well, but it was hard to tell. Pressing the screen didn't alter the spikes at all.

So, we turned it off before bed, then looked at it this morning, and it was fine!

Any thoughts?

Jo
