SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT -540A. Follow the manuf acturers’ instructions to use these
instruments.
2. A battery-operated A C milliammeter . The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC v oltmeter . The “limit” indication
is 0.75 V, so analog meters must have an accurate lo w-v oltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V A C range are suitable. (See

HCD-DZ230/DZ231/HDZ235
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.
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.
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
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)
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.
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.

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.)
MAIN board service position
Please take the above-mentioned position in the repair of MAIN board.
In that case, it is necessary the following extension cable during CN304 on IO-SCART board (DZ230/DZ231)/

2. Press the FUNCTION button to to set the function “ DVD”.
3. Insert ECM-AC2 supplied as an accessory into the AUDIO
IN/A.CAL MIC jack.
4. While pressing the X and A buttons simultaneously, turn
the VOLUME control in the direction of (+) .
5. Confirm that the following are shown on the display panel.
1 The JACK inserted/non-inserted detection display and the
STEREO/MONO detection display.
2 Presence of DIGITAL voice input to the microcomputer.
(OK: input, NG: no input)
3 The value of the MIC input to the microcomputer. (shown
“255h”)

10. DMPORT DEVICE TEST (DZ230/DZ231)
Procedure:
1. To enter this test mode, press the x , FUNCTION buttons
and turn the VOLUME control in the direction of (+)
simultaneously.
2. To e xit from this test mode, press the ?/1 button to turn the
power off.

11.PROTECTION FACTOR (SD DETECTION/
DC DETECTION) IDENTIFICATION TEST MODE
When an error is detected, the FL tube alternately displays
“PROTECTOR h PUSH POWER”.
Press the
r
* Buttons other than the
“STANDBY” blinks three times on the FL tube.
r
The protection release state (POWER OFF) is established.
(No FL tube display)
r Press the ?/1 button.
The power to the system turns on, and the normal operation is
established. (Restore)
During the protection state:
1. If the AC plug is connected or disconnected during the
protection state, the protection state is released, and the normal
operation is established. (The protection state is not
maintained.)
2. The protection factor is displayed by pressing the
FUNCTION , A and > buttons at the same time during
the protection state
(during the “PRO TECTOR h PUSH POWER” display).
k When SD is detected: Repeats
k When DC is detected: Repeats

“DC DETECT h PUSH POWER”.
PL: SD detection
When the “L” output from the SD (shutdown) port on the SMASTER POWER Driv er is detected, the power system other
than that of the FL tube is turned off, and the protection state
is established.
DC detection
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.

Ver. 1.1
SET
Procedure:
1. Turn the power on.
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.”
