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 PUB-
LISHED BY SONY.
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 of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
1. Check the area of your repair for unsoldered or poorly-sol-
dered 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 transis-
tors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recom-
mend their replacement.
5. Check the B+ voltage to see it is at the values specified.

6. REPLACING OPTICAL PICK-UP
6-1. 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 opti-
cal pick-up. (See Fig. 6)
Fig. 6 Flexible board
3) In handling the KHS-180A (RP), do not touch inhibited parts
shown in Fig. 7, but grip the slide base bearing and U-shaped
guide.
