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.

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 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 TV screen or front panel display. In this case, 
check the following table.

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

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.

E XX

(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.
