So I picked up a Performa 600 untested from a pawn shop for $15.  Brought it home, powered it on.  The power supply powers up, the hard drive spins up, but no chime and no video.

I replaced the PRAM battery (93) and no change.

I stripped everything off the motherboard, no change.

I inspected the top of the motherboard and do not seen any busted or leaky caps or any burn marks on the board.

Any suggestions on what to try next or should I just cannibalize it for parts?

Thanks
