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.
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 component in this product is capable
of emitting radiation exceeding the limit for
Class 1.

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 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.

SECTION 3
TEST MODE
HCD-VP800AV
[Cold Reset]
• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.
Procedure:
1. Press three buttons x , DISPLAY , and DISC 1
simultaneously.
2. The fluorescent indicator tube becomes blank instantaneously,
and the set is reset.
[Tuner Step Change] (Except for European and Middle Eastern
models)
• A step of AM channels can be changed over between 9 kHz and
10 kHz.
Procedure:
1. Press `/1 button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND button
to select the BAND “AM”.
3. Press `/1 button to turn the set OFF.
4. Press ENTER and `/1 buttons simultaneously, and the
display of fluorescent indicator tube changes to “AM 9 k ST”
or “AM 10 k ST”, and thus the channel step is changed over.
[GC Test Mode]
• This mode is used to check the software version, FL tube, LED,
keyboard and VACS.
Procedure:
1. Press three buttons x , DISPLAY , and DISC 2
simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
3. When you want to enter the software version display mode,
press DISC 1 .The model number and destination are displayed.
4. Each time DISC 1 is pressed, the display changes stating from
MC version, GC version, CD version, CDD, CDM version BD,
ST version, TA version, TM version, TC version, in this order,
and returns to the model number and destination display.
5. When DISC 3 is pressed while the version numbers are being
displayed except model number and destination, year, month
and day of the software creation appear. When DISC 3 is pressed
again, the display returns to the software version display. When
DISC 1 is pressed while year, month and day of the software
creation are being displayed, the year, month and day of creation
of the software versions are displayed in the same order of
version display.
6. Press DISC 2 button, and the key check mode is activated.
7. In the key check mode, the fluorescent indicator tube displays
“KOJOVO”. Each time a button is pressed, “KEY” value
increases.
However, once a button is pressed, _it is no longer taken into
account.
“VOL” value increases like 1, 2, 3...if rotating VOLUME knob
in “+” direction, or it decreases like 0, 9, 8...if rotating in
“_”direction.
8. Also when DISC 3 is pressed after lighting of all LEDs and FL
tubes, value of VACS appears.
9. To exit from this mode, press three buttons in the same manner
as step 1, or disconnect the power cord.
[MC Test Mode]
• This mode is used to check operations of the respective sections
of Amplifier, Tuner, and Tape.
Procedure:
• To enter MC Test Mode
1. Press the `/1 button to turn on the set.
2. Press the three buttons of x , DISPLAY and DISC 3
simultaneously.
3. Cursor segment flash on the FL display tube. The input
FUNCTION is changed to GAME.

TOOL MODE key: L , CR , SW through
1. When the VOLUME control knob is turned clockwise even
slightly, the sound volume increases to is maximum and a
message “VOLUME MAX” appears for two seconds, then the
display returns to the original display.
2. When the VOLUME control knob is tuned counter-clockwise
even slightly, the sound volume decreases to its minimum and a
message “VOLUME MIN” appears for two seconds, then the
display returns to the original display.
* Tuner function
1. In the test mode, the default-preset channel is called even when
the TUNER is selected and an attempt is made to call the preset
channel that has been stored in memory. (It means that the
memory is cleared.)
2. The minimum, center and maximum frequency of each band is
set then.
* Tape recording test
1. To enter the MC Test Mode.

5. Then the REW AMS is checked and the mechanism is shut off
after detecting the AMS signal twice.
6. When the check is complete, a message of either OK or NG
appears.
* To return to normal mode again.
1. When you want to exit this mode, press the `/1 button.

[VIDEO CD Color-bars Mode]
On this mode, the data of the color-bars signal as a picture signal
and the 1 kHz sine wave signal as a sound signal are output by the
mechanism controller (IC502) for the video CD signal check. When
measurement of the voltage and waveform on the VIDEO board,
perform it in this mode.
For reference, the color-bars signal can be observed at J302 using
an oscilloscope.
Procedure:
1. Short the both ends of the land of SL503 of the VIDEO board.
2. Turn the power on. Press the CD button to select CD.
