Vaio LT1M Display problems

[jumpsuit]

Hi all

My beloved 'desktop' has a problem.
I have all sorts of lines on the display.
I think it began with the pc shutting itself down the other night.

At first we thought it may have been
an overheating and checked the internal cpu - which showed 80 across the board

After taking the back off and cleaning vents and what parts of the fans were accessible,
I rebooted and all was well for a while - temps dropped back to 65-70 degrees.
After 5 minutes the lines reappeared and since then have appeared from startup even after a cold boot.

I'm now wondering whether its the graphics card itself. Didn't manage to locate it on first look inside it.

Any ideas without taking the back off again?

EDIT: Now worried that the Nvidia chip is incorporated into the motherboard. Can any users confirm this as his would mean a motherboard replacement.

Hi Jumpy,

Doesn't look good, sounds like a chip problem to me and yes the NVidia GeForce 8400M GT is soldered to the mother board..

Hi Jumpy,

It looks like you have your own personal version of 'Space Invaders'.

Time to phone Vaio-Link before a queue forms!!!!!
