MODEL IDENTIFICATION
– Rear Panel –

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 bottom 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)

Parts No.

: 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
IN SUPPLEMENTS PUBLISHED BY SONY.

SECTION 1

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 a ctivated 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 followin g table.

DISC SLOT LOCK

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

Setting Procedure :

1. Press the ?/1 button to turn the set on.

2. Press the [FUNCTION] button to set DVD function.

3. Insert a disc.

4. Press the

x stick and the A button simultaneously for five

seconds.

5. The message “LOCKED” is displayed and the slot is locked.

Releasing Procedure :

1. Press the x stick and the A button simultaneously for five
seconds again.

2. The message “UNLOCKED” is displayed and the slot is
unlocked.

Note: When “LOCKED” is displayed, the slot lock is not released by

Because the number of the operating buttons of this product
are limited, some operations require use of the operating
buttons of the remote commander, When a specific operation
requires use of the operating buttons of the remote commander,
“R” is added to the specific operating procedure in this manual.

for 5 seconds or longer.
Then remove your fingers from the above stick and the button.
The message “UNLOCKED” appears for 2 seconds and the disc
tray opens.

Note on DMB10 board replacement

IC103 (EEP ROM) on DMB10 board can not be replaced
individually. Replace it with DMB10 board, complete for service.
So, carry IC103 (EEP ROM) again at the time of DMB10 board
exchange.

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.
