I have a MAC Performa 550 that was working fine before I put it away. I
just took it out and hooked it up. When I turned it on there was a quick
indication of power and then nothing. Is there any kind of fuse in these
machines or is it probably dead.
Help

Replace the PROM battery. A dead battery takes out the video first on
those guys.

I second the PRAM (Parameter RAM) battery fix. Also, if you turn the machine
on, it powers up then nothing, if you do a hard reset once or twice it
should boot normally, but with all PRAM settings set to default (IE clock
set to "Date of Antiquity") After replacing the PRAM battery, make sure to
zap your PRAM at first boot to get a clean default setup by holding down
command-option-p-r (I think) on first boot. Let it reset three times, then
let it boot.
Hey, at least they behave better than when those old Sun NVRAM clockchip
batteries die :)

You might want to check if the PSU fan spins. If not, the fuse - buried
within the PSU - may be blown. Otherwise, the battery is the next shot.
