I picked up a 1.25GHz 17 inch iMac G4 at VCF East this weekend but despite being in very nice shape overall, it seems to be troubled. When you press the power button it bongs like normal and the internal fan spins, but the screen never comes on. I've already tried pulling the RAM (it was already upgraded to 2GB, nice!) and cleaning the slots but it had no effect, what else could I try? The only other thing I can think of is to pull the PRAM battery and press the PRAM reset button (assuming there is one), but I'm not sure if the problem here is with the display panel or the rest of the computer.
