Title:

Power Mac G5 won't start

Text:

Late 2005 Power Mac G5 (Model A1047) does not power up. It fires up, the power button light on the monitor blinks (single blinks about every 4 seconds) but the monitor does not light up. The fan in the tower does start running after its on for sometime, but no display or anything else. Tried the cudo (?) button (for one second first and again for 30 seconds as suggested on a forum), and resetting the PRAM (command+option+P+R), force shutdown..... nothing works. I have 4x 1 GB RAM installed and they are paired.

This is a hand down computer that has been sitting idle for months (maybe even a year) now. Not sure if that is the issue. Any help is appreciated.

Thanks!
