They are now telling me that the motherboard will need to be replaced, as the video card is onboard, but I've hooked the laptop to an external monitor and the photos look normal. That makes me think that the video card is not the culprit.
I've also updated the video driver and even the BIOS to no avail.
All I can think is that maybe something is not connected properly or perhaps the first tech messed something up. Anyone have any ideas?
