Defective Assy Reason for Power-down Point to be Checked Possible Defective Part Remarks
MR POWER
Disconnection of cable detected Disconnection of cable detected Disconnection of cable detected Disconnection of cable detected
Power-down caused by detection of middle-point voltage Power-down caused by detection of middle-point voltage
Power-down caused by detection of a power surge
If the elapsed time from relay-on until the LED in the power supply unit lights is about 2-4 seconds, the defective assembly may be the 43 X or Y DRIVE.
