SELF DIAGNOSIS FUNCTION
Self-diagnosis Function
(When letters/numbers appear in the
display)
When the self-d iagnosis fun ction i s activ ated
to prevent the player from malfunctioning, a
five-charact er service number (e.g., C 13 50)
with a combination of a letter and four d igits
appears on the screen and the fr ont panel
display. In this case, check the following
table.

player enters standby mode .
,Check that there is
nothing wrong inside the
rotary table, such as a
fallen disc. After you
have checked the inside
of the rotary table and
resolved any possible
problems, press H.
To prevent a malf unction, the
player has performed the
self-diagnosis function.
,Contact your nearest
Sony dealer or local
authorized Sony service
facility and give the 5character ser vi ce number.

Notes on chip component replacement
•Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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 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 leaka ge from an y 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. Follo w the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC 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 A C voltmeter . The “limit” indication is 0.75
V, so analog meters must have an accurate low-voltage 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 Fig. A)
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
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.

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 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
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objectiv e lens.
NOTE OF REPLACING THE MB BOARD
When replacing the MB board, since the adjustment value is not

Memory Check”. (See page 32)
4. Press the [CLEAR] key of the remote commander, and initialize Memory.
CHECK OF POWER BOARD WITH THE POWER ON
It is possible to analyze the defect with only POWER board power
ON.
Procedure:
1. Set to power OFF state.
2. Remove the connector from CN201 on the POWER board.
3. Short between CN201 pin 1 (P-CONT) and CN201 pin qa
(EVER+3.3V) on the POWER board.
4. Turn the power ON.
5. Confirm that the voltage value of CN201 each pin on the
POWER board satisfy following value .
CN201 Pin Voltage Value
pin 2 (EVER–11V) –11V
pin 3 (SW–11V) –11V
pin 6, 7 (SW+11V) +11V
pin 8 (SW+3.3V) +3.3V

ARP (IC301) through the bus, then they are read and
checked. In case of discord, written bit pattern and read
data are displayed. If data where multiple bits are 1 are
read, the bits concerned may touch each other. Further, if
data where certain bit is always 1 or 0 regardless of written
data, the line could be disconnected or shorted.
(5-4) ARP to RAM Address Bus

Error 10: ARP Tt RAM address bus error
Caution: Address and data display in case of an error is
different from the display of other diagnosis (described
later).
Before starting the test, all addresses of RAM (IC303) are
cleared to 0x0000.
First, 0xA55A is written to the address 0x00000, and the
address data are read and checked from addresses 0x00001
to 0x80000 while shifting 1 bit each. Next, the data at that
address is cleared, and it is written to the address 0x00001,
and read and checked in the same manner. T his check is
repeated up to the address 0x80000 while shifting the address data by 1 bit each.
If data other than 0 is read at the addresses except written
address, an error is given because all addresses were already cleared to 0. In this check, the error display pattern is
different from that of other diagnosis; read data, written
address, and read address are displayed in this order. Ho wever, the message uses same template, and accordingly exchange Address and Data when reading. T he following display, for example,
### Syscon Diagnosis ###

shows the data 0xA55A was read from address 0x00080000
though it was written to the address 0x00000000. This implies that these addresses are in the form of shadow. Also,
if the read data is not 0xA55A, another error will be present.
(5-5) ARP RAM Check
Data write t read, and accord check
Error 11: ARP RAM read data discord
The program code data stored in ROM are copied to all
areas of RAM (IC303) connected to the ARP (IC301)
through the bus, then they are read and checked if they accord. If the detail check was selected initially, the data are
written to all areas and read, then the same test is conducted
once again with the data where all bits are inverted between
1 and 0. If discord is detected, faulty address, written data,
