In spite of the display will the drives enable?
The damage may be limited to the EPSON display. Do not know where to get another. You could try EMI-INC.net.
But I would check the output of both logic power supplies and the drive power supplies to see if they are all within tolerance.
One logic power supply is in the wire way going to the front panel. The other is on the bottom right of the electrical cabinet.
All values are given in the trouble shooting section of the maintenance manual.
