Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• 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.

UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE
WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN
THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.
REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE
PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR

SERVICING NOTE
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 OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveform is output several times.
Self-diagnosis Function
(When letters/numbers appear in the
display)
When the s elf -diagnosis function is activated to
prevent the system from malfunctioning, a 5character service number (e.g., C 13 50) with a
combination of a letter and 4 digits appears on
the screen and the front pa nel display. In this
case, check the following table.

4-1. GENERAL DESCRIPTION
The Mirror Time and IOP measurement allows you to make
diagnosis and adjustment simply by using the remote commander
and monitor TV. The instructions, diagnosis results, etc. are given
on the on screen display (OSD).
The Mirror Time and IOP measurement is required is such events
where servicing a DVD-Player includes changing the Base Unit
(BU). For each new BU to be used with a certain MV-044 board,
Mirror Time and IOP measurement need to be carried out.
4-2. STARTING TEST MODE
Press three buttons x , A and VOLUME + simultaneously
with the DVD player in standby mode.
The Test Mode starts, then the menu shown below will be
displayed on the TV screen.

This command checks the Mirror time value for DVD disc.
3. Threshold
This command displays the threshold value between CD and DVD
mirror time.
4. Save to EEPROM
This command saves an adjusted mirror time value to the EEPR OM.
5. Default set MIRR time
This command will set CD and DVD mirror time to fir mware default
value.

Procedure:
1. Conect an oscilloscope to CN105 pin 6 (RFMON) and CN105
pin 3 (GND) on the DMB10 board.
2. Turn the power on.
3. Insert the CD test disc (refer to the TEST DISC LIST), and
press the H button to play the disc back.
4. Confirm that oscilloscope waveform is clear and check RF
signal level is correct or not.
Note: A clear RF signal waveform means that the shape “◊” can be
clearly distinguished at the center of the waveform.
5. Eject the CD disc, and insert the DVD SL test disk (refer to the
TEST DISC LIST), and press the H button to play the disc
back.
