Self-diagnosis Function.

(When letters-numbers appear in the display)

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

When the version number appears on the TV screen.

When you turn on the system, the version number [VER.X.XX] (X is a number) may appear on the TV 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.

How to open the disc table when power switch turns off Insert a tapering driver into the aperture of the unit bottom, and slide it in the direction of the arrow.

Insert a screwdriver from between the front panel and the chassis and slide the rod in the direction of the arrow.

Precaution when installing a new OP unit-Precaution before unsoldering the static electricity prevention solder bridge.

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.)

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

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.

NOTES ON LASER DIODE EMISSION CHECK

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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

LASER DIODE AND FOCUS SEARCH

1. Open the case and turn POWER on with no disc inserted.

2. Confirm that the following operation is performed while observing the objecting lens from the clearance of DVD mechanism deck.

1) Confirm that laser beam is spread.

2) Up and down motion of the objective lens. (2 times)
