Dan is right on this one.

Have had many 3000's fail with black screens.  It will be a chore but it is going to be trace or chip related for sure.

You can try pressing the caps lock multiple times and if the light freezes after 5 times the cpu isn't responding.

as matt3k said I press 5 times, keyboard led stop working, when ı reset from keyboard scsi drive also reset and keyboard led blink once as usual
