The laser diode in the optical pick-up block may suffer electro-
static 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 emis-
sion, observe from more than 30 cm away from the objective lens.

Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveforms is output three times.

In checking the DSP/MB/MC/VIDEO boards, prepare jig.

Specification of this set is changed in the midway of production.
Therefore, the set is classified into two types according to which
IC, IC204 or IC205, is mounted.
When replacing IC205 of type A, install IC204 instead of IC205.

IC205 (48 pin) is mounted : TYPE A

IC204 (44 pin) is mounted : TYPE B

The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.

Releasing Procedure :
Press two buttons of 

Z

 (DVD) and 

[DVD TOP MENU]

 simulta-

neously for five seconds. The message “UNLOCKED” is displayed
and the tray is unlocked.

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

[I/   ]

 button.

When replacing the MB board, since the adjustment value is not
set up correctly, “Drive Auto Adjustment” can’t be performed.
In this case, initialize Memory in the following procedures.

Procedure:
1. Set the test mode. (See page 28)
2. Press the 

[2]

 key of the remote commander, and set the “DRIVE

MANUAL OPERATION”. (See page 30)

3. Press the 

[6]

 key of the remote commander, and set the “2-6,

Memory Check”. (See page 32)

4. Press the 

[CLEAR]

 key of the remote commander, and initial-

ize Memory.
