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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation

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 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 AC 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 AC range are suitable.  (See
Fig. A)

(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 screen and the front panel display. 
In this case, check the following table.
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.
Self-diagnosis function (DVD function only)

C 13
The disc is dirty.
Clean the disc with a soft cloth.
C 31
The disc is not inserted correctly.
Restart the system, then re-insert the disc correctly.

(xx is a number)
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.

DIAGNOSTIC  TEST  INDICATORS
When an error occurs, the [POWER] LED will flash a set number of
times to indicate the possible cause of the problem. If there is more
than one error, the LED will identify the first of the problem areas.
If the errors occur simultaneously, the one that corresponds to the
fewest flashes is identified first. Results for all of the following
diagnostic items are displayed on screen. No error has occurred if
the screen display a “0”.

The units in this manual contain a self-diagnostic function. If an error occurs, the [POWER] LED will automatically begin to flash. The
number of times the LED flashes translates to a probable source of the problem. A definition of the [POWER] LED flash indicators is listed
in the instruction manual for the user’s knowledge and reference. If an error symptom is difficult to reproduced use the remote commander
to display the record that is stored at the internal NVM to specify the cause of the failure.
