SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT

The laser diode in the optical pick-up block may suffer
electrostatic breakdown because of the potential difference
generated by the charged electrostatic load, etc on clothing
and the human body.

During repair, pay attention to electrostatic breakdown and
also use the procedure in the printed matter which is
included in the repair parts

The flexible board is easily damaged and should be handled
with care.

Flexible clrcult Board Repalrlng

° 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.

Notes on chip component replacement

' Never reuse a disconnected chip component.

0 Notice that the minus side of a tantalum capacitor may
be damaged by heat.

Before Replaclng the Optlcal Block

Please be sure to check thoroughly the parameters as for
the Optical Block Checking Procedures (Part No. :9-960-
OZ7~ll) issued separately before replacing the optical block.
Note and specifications required to check are given below.

- FOK output: IC501©pin
When checking FOK, unsolder bridge between IC501 @pin
(FE) and R553.

~ S carve P-to-P value: 2.95 Vp-p

. Adjusted part for focus gain adjustment: RV503

- RF signal P-to-P value: 0.75-1.41 Vp-p

- Traverse signal P-to-P value: 1.8Vp-p

- The repairing grating holder is impossible.
