Information of MAN, DRV, SID and HDM Circuit Boards
[PATTERN No.JA2084-4]During servicing, replace the entire MAN circuit board, and the entire [PATTERN No.JA2084-4]
disc drive unit, including the DRV, SID and HDM circuit boards.
Note: Voltage values are in reading status.Because of this servicing method, this service manual includes only the
Example: 24 (4.7): Terminal no. (voltage value)simplified circuit board diagrams, and does not include any schematic
circuit diagrams.
Supplement: Since the DVD drive is intermittently operated, set to the reading status in whichThe simplified circuit board diagrams show the major voltage values:
laser light is emitted from the pickup.Refer to them during troubleshooting.
