As for MAIN board and POWER board, the suffix of a board
has been changed with running change.

MAIN board : 11 t 12

POWER board : 12 t 13
Please see SUPPLEMENT-1 about the information on
MAIN board suffix -12.
POWER board suffix -13 doesn’t change pattern.
It is described in parallel in this original service manual.

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.
This marking is located on
the rear exterior.
(Except for Korean model)

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
IN SUPPLEMENTS PUBLISHED BY SONY.

Special Component Notice

The components identified by mark 9 contain confidential
information.
Strictly follow the instructions whenever the components are repaired
and/or replaced.

Self-diagnosis Function

(When letters/numbers appear in the
display)

When the self-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 panel display. In this
case, check the following table.

C:13:50

HCD-DZ150K/DZ151KB

First 3
characters of
the service
number

C 13 The disc is dirty.

C 31 The disc is not inserted correctly.

E XX
(xx is a number)

Cause and/or 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 self­diagnosis function.

,Contact your nearest Sony

dealer or local authorized Sony
service facility and give the 5­character service number.

Example: E 61 10

When displaying the version
number on the screen

When you turn on the system, the version
number [VER.X.XX] (X is a number) may
appear on the 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.

SERVICING NOTE

HCD-DZ150K/DZ151KB

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.

Precaution when installing a new OP unit /
Precaution before unsoldering the static electricity prevention solder bridge

When installing a new OP unit, be sure to connect the flexible printed circuit board first of all
before removing the static electricity prevention solder bridge by unsoldering.
Remove the static electricity prevention solder bridge by unsoldering after the flexible printed
circuit board has already been connected.
(Do not remove nor unsolder the solder bridge as long as the OP unit is kept standalone.)

When the “L” output from the power/speaker error detection
circuit (DC detection port) is detected for two seconds
continually, the po wer system other than that of the FL tube is
turned off, and the protection state is established.

10. Color System Change-over
(Except Mexican and Latin American models)

It is a mode to switch the color system (PAL/NTSC).

Procedure:

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

2. Press the FUNCTION button to set the function “DVD”.

3. Press the ?/1 button to turn the power off.

4. While pressing the X butt on, press the ?/1 bu tton
simultaneously.

5. Each time you perform this operation the color system toggles
between P AL and NTSC. “NTSC” lights up in the front display
when “NTSC” is selected.

When the optical pick-up assy is replaced, perform the
“EXECUTING IOP MEASUREMENT”.

generator

SET

Procedure:

1. Turn on the set.

2. Input the following signal from Signal Generator to FM
antenna input directly.

* Carrier Freq: A = 87.5 MHz, B = 98 MHz, C = 108 MHz

Deviation : 75 kHz
Modulation : 1 kHz
ANT input : 35 dBu (EMF)

Note: Please use 75 ohm “coaxial cable” to connect SG and the set. You

cannot use video cable for checking.
Please use SG whose output impedance is 75 ohm.

3. Set to FM tuner function and tune A, B and C signals.

4. Confirm “TUNED” is lit on the display for A, B and C signals.

The mark of “TUNED” means “The selected station signal is
received in good condition.”

For Schematic Diagrams.
Note:

• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except f or electrolytics and
tantalums.

• All resistors are in Ω and 1/
specified.

• f : internal component.

• C : panel designation.
Note: The components identified by mark 0 or dotted

line with mark 0 are critical for safety.
Replace only with part number specified.

• A : B+ Line.

•Voltages and wavef orms are dc with respect to ground un­der no-signal (detuned) conditions.

•Voltages and waveforms are dc with respect to ground in
service mode.

•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
no mark : DVD STOP
* : Impossible to measure

•Voltages are taken with VOM (Input impedance 10 MΩ).

• Circled numbers refer to waveforms.
