Let us try the basics:

1. Please post the monitor model you are using and describe the monitor video cable too. You need a known working video cable, SUN 13w3 -> VGA adapters often sold on eBay don’t work. However SUN 13w3 -> 13w3 cables connected to SGI monitors do tend to work.

2. Disconnect all the wires to all Hard drives, see if it boots to firmware. Hard drive is not needed to start machine, hard drive may have an electrical problem that is causing startup problems or power supply is too weak. Either way simplify the system and try again.

Good luck.
