Have you reset the power manager? Ctl/opt/Apple/restart with
power/batt off for half hr.
No way for CompUSA, or any other commercial repair. You can do it
yourself, as the 5XX's are so modular that there's no reason for paying
techies.
Get the service manual, and swap back the 040 to narrow down the
problem. Might be the PPC daughtercard. If it still doesn't work, then
you know that the most expensive part isn't the problem. Probably the
motherboard, then.
