Information of MAN-H/MAN,DRV-R,
MOD and HDM Circuit Boards
If a fault is located on the MAN-H/MAN circuit board,
the entire circuit board must be replaced for servicing.
If there is a fault in the DRV-R, MOD or HDM circuit
board, the entire disc drive unit must be replaced, since
these circuit boards are included in this unit.
Because of this servicing method, this service manual
does not include any schematic circuit diagrams.
For circuit board diagrams, the manual includes the simple
diagrams, which show only the information that is necessary
for troubleshooting.
