Don't be so fast to give up. Look at the cans on the logic board. Do any have corrosion on the tops? Are any of them bulged? Do they look like this?http://images.google.com/images?client=s...

Now look at tthe power supply and see if you any burn marks on it. Hit the reset button on the power supply power.

Diagnostic LED's for that model

# 1 Trickle Power from Power Supply

# 2 Computer On

# 3 LCD and Video Communication Good.

Is Led #1 nice and bright without flickering? sometimes you can have a bad power supply, and still get trickle voltage. if its not the power supply - its probably a bad logic board. there are some other parts inbetween.. but rarely do they fail.. cable, AC/DC board.. etc.
