G5 iMac will chime on startup, Indicator light will glow then go out. Black screen and no sound on iMac. Also black screen on external monitor when setup for external monitor. Hard drive will appear and open for full access. on my iBook when attached via FireWire to the iMac and "T" key is held down on iMac. Any idea as to what's wrong or needs to be replaced.
