Service Note - Sony DVP-CX860 Service Manual

1. REPLACING OPTICAL PICK-UP
1-1. Handling
A red laser diode for DVD requires more attention to static electricity
than general infrared laser diodes for CD.
Because its durability to static electricity is far weaker than that of
infrared laser diodes, always use an earth band when handling the
optical pick-up block as service parts.
1-2. When the turntable is removed, be sure to
perform the sensor adjustment.
Refer to "8. 300 CHG Mecha Con Menu 2" of Section "6. TEST
MODE" (page 6-10) for the adjustment procedure.
1-3. How to service MB-94 board
Establish the equipment setup as shown in illustration using the jig
(J-6090-102-A) referring to Section "2-1. OVERALL" of DISAS-
SEMBLY.
