Hope for the best and prepare for the worst.
This old Dell has a semi-permanent problem resembling this. The screen
works normally for about one second on the POST, and again whenever
you press a key after the screen had blanked. So it's only usable with
a VGA monitor connected. However, the monitor doesn't display the CMOS
screen which limits options.
The rest of the time, the display is trying to work, odd flickers can
be seen as it switches modes, and once X is running it's just possible
to make out a glimmer from windows that have white backgrounds.
I can only think that it's a firmware/hardware bug. A blown capacitor
is the first thing that spring to mind.
Cheers,
David.
