There was power outage after which when the equipment was powered on, it worked normally for some time the later when I power it on now, it only displays nothing on main monitor and the two smaller ones. It didn't show any information on the software either. Please what could be the problem? I am thinking the software is corrupt may be I may need to load another one but I don't have the diskette from which I can load. Please if this is the problem how can I get the diskette or any solution to the problem? I will appreciate your responses.

Check your voltages on the power supply on the back, there is a HV section that supplies the monitor on that. Also check your voltages on the power regulator board i had a similar problem, got it fixed by replacing that.
