The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down 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.

The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

1. Open the cover and turn POWER on with no disc inserted.
2. Confirm that the following operation is performed while

observing the objecting lens.
1) Confirm that laser beam is spread.
2) Up and down motion of the objective lens. (3 times)

When “LOCKED” is displayed, the tray lock is not released by
turning power on/off with the  ?/1  button.

New part of EEP ROM (IC1103) on the MAIN board cannot be used.
Therefore, if the mounted MAIN board (A-1151-985-A, etc.) is replaced,

exchange new EEP ROM (IC1103) with that used before the replacement.

When the self-diagnosis function is activated to 
prevent the system from malfunctioning, a 5-
character service number (e.g., C 13 50) with a 
combination of a letter and 4 digits appears on 
the screen and the front panel display. In this 
case, check the following table.

When you turn on the system, the version 
number [VER.X.XX] (X is a number) may 
appear on the screen. Although this is not a 
malfunction and for Sony service use only, 
normal system operation will not be possible. 
Turn off the system, and then turn on the system 
again to operate.

When installing a new OP unit, be sure to connect the flexible
printed circuit board first of all before removing the static electricity
prevention solder bridge by unsoldering. Remove the static electricity
prevention solder bridge by unsoldering after the flexible printed
circuit board has already been connected. 
(Do not remove nor unsolder the solder bridge
as long as the OP unit is kept standalone.)

When processing the connectors of the POWER board, be sure to refer to section “3-8. POWER BOARD” (page 16).
