XServer dead...won't boot, no signal to monitor although fans start up... ?
We've got a Mac server that's decided to fail. It has been crashing over the last few days, requiring a hard reset, but we didn't have the time to properly investigate what was going wrong with it.
Anyway, we've come in this morning and it won't boot. The fans start, we have a single green light and a amber light which flashes 3 times. There's no signal to the monitor.
removing power cables, holding the power button while unplugged to drain the caps - no change
removed the watch battery on the main board - no change
re-seated the ram - no change
anyone got any ideas?
