I am working on a Sony Vaio PCG-7H1L, it starts booting, gets to the bios screen, then starts to boot for a few seconds before the video cuts out to a black screen. I have tried an external monitor, where I get no display at all. Tried booting from a knoppix CD, same thing, a few seconds of video then it cuts out. Tried it without the battery, same thing. I can hear it booting up with the video off, and the music plays when xp get to the desktop. I would have suspected a dead screen except for the fact that it works at the bios screen and for a few seconds after. Anybody have any ideas?
