SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK
! OR DOTTED LINE WITH
MARK
! ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY.
1.
Check the area of your repair for unsoldered or poorly-soldered
connections. Check the entire board surface for solder splashes
and bridges.
2.
Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
3.
Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
4.
Look for parts which, through functioning, show obvious signs
of deterioration. Point them out to the customer and
recommend their replace-ment.
5.
Check the B+ voltage to see it is at the values specified.
6.
Flexible Circuit Board Repairing
· Keep the temperature of the soldering iron around 270°C
during repairing.
· Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
· Be careful not to apply force on the conductor when soldering
or unsoldering.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
WARNING!!
WHEN SERVICING, DO NOT APPROACH THE LASER
EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS
NECESSARY TO CONFIRM LASER BEAM EMISSION,
BE SURE TO OBSERVE FROM A DISTANCE OF MORE
THAN 25 cm FROM THE SURFACE OF THE OBJECTIVE
LENS ON THE OPTICAL PICK-UP BLOCK.
CAUTION:
The use of optical instrument with this product will increase eye
hazard.
CAUTION
Use of controls or adjustments or performance procedures other
than those specified herein may result in hazardous radiation
exposure.
NOTE
There is no screw at three screwing marked "
" positions on the
bottom originally at the factory.
But there is no problem when screwing in using the screws 3 mm
(dia.)
× 10 mm (length).

DISK REMOVAL PROCEDURE (at POWER OFF)
1)
Insert a cross-tip screwdriver into a hole at the bottom, and rotate the cam gear 1 in direction A. (See Fig. 1)
Note: To prevent a damage of cam gear, rotate it in direction A by 1/4 turn.
2)
Draw out the tray 2 in direction B by hand, and remove a disk. (See Fig. 1)
Fig. 1
2.
NOTE ON MOUNTING SLED MOTOR
1)
Push the sled motor assy 1 toward direction A. (See Fig. 2)
2)
Tighten two screws 2 (M1.7
× 2.5).
Fig. 2
3)
Raising the MD block assy 3 90 º with the side down. confirm that the optical pick-up 4 falls by self weight. (See Fig. 3)
4)
Further, with the front side of MD block assy 3 up, confirm that the optical pick-up falls by self weight.

REPLACING OPTICAL PICK-UP
3-1.
Handling
1)
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.
2)
As for the flexible board KHS-180A (RP) packed as service
parts, the short lands have been soldered to protect from static
electricity. Accordingly, remove solders when replacing optical
pick-up. (See Fig. 4)
Fig. 4 Flexible board
3)
In handling the KHS-180A (RP), do not touch inhibited parts
shown in Fig. 5, but grip the slide base bearing and U-shaped
guide.
Touch inhibited parts

· Skew sensor
· Laser holder
· Laser coupler
· Flexible board
· OEIC
· Lens actuator covers
