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 a
combination of a letter and 4 digits appears on
the TV screen and the front panel display. In this
case, check the following table.

First 3
characters of
the service
number

C 13 This disc is dirty.

C 31 The disc is not inserted correctly.

E XX
(XX is a
number)

When displaying the version number 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.

Cause and corrective action

Clean the disc with a soft cloth

Restart the system, then re-insert

the disc correctly.

To prevent a malfunction, the system
has performed the self-diagnosis
function.

Contact your nearest Sony dealer or

local authorized Sony service
facility and give the 5-character
service number.
Example: E 61 10

SECTION 1

SERVICING NOTES

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 fl exible 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 refl ective 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.

CAUTION

Use of controls or adjustments or performance of procedures other than
those specifi ed herein may result in hazardous radiation exposure.

This appliance is classifi ed as a
CLASS 1 LASER product.
This marking is located on the
rear or bottom exterior.

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 fl ow)

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.

NOTE OF REPLACING THE IC101 AND IC103 ON THE
DMB18 BOARD

IC101 and IC103 on the DMB18 board cannot exchange with
single. When these parts on the DMB18 board are damaged,
exchange the entire mounted board.

MODEL IDENTIFICATION

-Back Panel-

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 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.

SAFETY-RELATED COMPONET 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.

TEST MODE

[GC TEST MODE]

• This mode is used to check the fl uorescent indicator tube,
LEDs, keys, VOLUME jog, OPERATION DIAL jog, model,
destination and software version.

Procedure:

1. Press [x] button, [ENTER] button and [DISC 2] button simul­taneously.

2. All LEDs and segments in fl uorescent indicator tube are light-
ed up. All LEDs are lighted up in blue color except for [
LED where the LED is lighted up in red and blue color, [SUB­WOOFER ON/OFF] LED in green color and METER BACK­LIGHT LED and POWER LED in red color.

3. When you want to enter to the software version display mode,
press [DISC 1] button. The model and destination information
appears on the fl uorescent indicator tube.

4. Each time [DISC 1] button is pressed, the display changes to
display software version and date of the software creation. The
sequence is model destination, SC, GC, SYS, DVD, ST, TC,
TA, TM and MTR in this order, and returns to the model desti­nation display.

5. Press [DISC 2] button, the key check mode is activated.

6. In the key check mode, the fl uorescent indicator tube displays
“K 0 J0 V0”.

Turn the [OPERATIONAL DIAL] clockwise; ”J” value in-

creases by one. Turn the [OPERATIONAL DIAL] counter­clockwise; “J” value decreases by one. Each time a button is
pressed, “K” value increases. Press other keys on main unit
to check whether the key is detected. However, once a button
has been pressed, it is no longer taken into account. “V” value
increases in the manner of 0,1, 2, 3 ... if [VOLUME] knob is
turned clockwise, or it decreases in the manner of 0, 9, 8,7 ...
if [VOLUME] knob is turned counterclockwise.

LEDs and segments in fl uorescent indicator tube light up, al-
ternate segments in fl uorescent indicator tube and LED would
light up. If you press [DISC SKIP/EX-CHANGE] button again,
another half of alternate segments in fl uorescent indicator tube
and LED would light up. Press [DISC SKIP/EX-CHANGE]
button would cause all segments in fl uorescent indicator tube
and LED turns off. Press [DISC SKIP/EX-CHANGE] button
again would cause all segments and LED lights up.

8. When [DISC SKIP/ EX-CHANGE] button is pressed after all
LEDs and segments in fl uorescent indicator tube light up, al-
ternate segments in fl uorescent indicator tube and LED would
light up. If you press [DISC SKIP/ EX-CHANGE] button
again, another half of alternate segments in fl uorescent indi-
cator tube and LED would light up. Press [DISC SKIP/ EX­CHANGE] button again would cause all segments lights up.
