Notes
• Note about DVD-RWs/DVD-Rs, DVD+RWs/
DVD+Rs, or CD-Rs/CD-RWs.
Some DVD-RWs/DVD-Rs, DVD+RWs/
DVD+Rs, or CD-Rs/CD-RWs cannot be played 
on this player due to the recording quality or 
physical condition of the disc, or the 
characteristics of the recording device and 
authoring software. Also, images in DVD-RWs  
with CPRM* protection may not be played if they 
contain a copy protection signal. “Copyright 
lock” appears on the screen. For more 
information, see the operating instructions for the 
recording device.
Note that discs created in the Packet Write format 
cannot be played.
* CPRM  (Content Protection for Recordable 
Media) is a coding technology that protects 
copyright for images.
• Music discs encoded with copyright protection 
technologies
This product is designed to playback discs that 
conform to the Compact Disc (CD) standard. 
Recently, various music discs encoded with 
copyright protection technologies are marketed 
by some record companies. Please be aware that 
among those discs, there are some that do not 
conform to the CD standard and may not be 
playable by this product. 
Note on playback operations of 
DVDs and VIDEO CDs
Some playback operations of DVDs and 
VIDEO CDs may be intentionally set by 
software producers. Since this player plays 
DVDs and VIDEO CDs according to the disc 
contents the software producers designed, 
some playback features may not be available. 
Also, refer to the instructions supplied with 
the DVDs or VIDEO CDs.

SECTION  1
SERVICING  NOTES
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.
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
pick-up block. Therefore, when checking the laser diode emis-
sion, observe from more than 30 cm away from the objective lens.
NOTE  OF  REPLACING  THE  MB  BOARD
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 23)
2. Press the [2] key of the remote commander, and set the “DRIVE
MANUAL OPERATION”. (See page 29)
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.
SETTING  OR  RELEASING  THE  FRONT  COVER  LOCK
Procedure:
1. Press the

button to turn the power on.
2. Press two buttons of
x
and [OPEN/CLOSE] on the main unit
for 5 seconds or more.
Note:
The setting method and the releasing method are the same operation.

CHECK  OF  POWER  BOARD  WITH  THE  POWER  ON
It is possible to analyze the defect with only POWER board power
ON.
Procedure:
1. Set to power OFF state.
2. Remove the connector from CN201 on the POWER board.
3. Short between CN201 pin 1 (P-CONT) and CN201 pin qa
(EVER+3.3V) on the POWER board.
4. Turn the power ON.
5. Confirm that the voltage value of CN201 each pin on the
POWER board satisfy following value .
CN201 Pin
Voltage Value
pin 2 (EVER–11V)
–11V
pin 3 (SW–11V)
