YN
Go to 01H and follow the procedure for the media path driver PWB.
Refer to WD 1.5. Disconnect PJDC4 from the power supply unit and check for a short circuit
between pins 17 to chassis and from pin 18 to the chassis with the PJDC4 disconnected.
The
circuit is good.
YN
Go to 01H and follow the procedure for the power distribution PWB.
No short has been found in the +24V circuits, refer to the fault history for an insight into the
fault area, then go to 01H and check that area.
