SELF-DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/STEREO 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 STANDBY/STEREO LED
flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the
Remote Commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these
problems occur.
Diagnostic Test Indicators
When an error occurs, the STANDBY/STEREO 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. Due to a hardware upgrade, there is no LED flashing in
sets using Ver.1.0 system micros. This has been addressed in Ver.2.0 system micros.
Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

Handling of Self-Diagnostic Screen Display
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during
repairs. When you have completed the repairs, clear the result display to “0”.
Unless the result display is cleared to “0”, the self-diagnostic function will not be able to detect subsequent faults after completion
of the repairs.
Clearing the Result Display
To clear the result display to “0”, press buttons on the Remote Commander sequentially when the diagnostic screen is displayed,
as shown below:
ENTERChannel 8
Quitting the Self-Diagnostic Screen
To quit the entire self-diagnostic screen, turn off the power switch on the Remote Commander or the main unit.
Self-Diagnostic Circuit
+B overcurrent (OCP) Occurs when an overcurrent (more than 6A) on the +B (135V) line is detected by R6598/
R6591. It will cause Q6520 to turn on and force the AC relay to turn off through Q6532 and
Q6530.
+B overvoltage (OVP) Occurs when 1) overvoltage (more than +140V) on the +B (135V) line is detected by IC6505
or 2) an overvoltage (more than 7.5V) on the unreg 7V line is detected by D6014. The AC
Relay will turn off through Q6532 and Q6530.
Vertical Deflection Stopped Occurs when an absence of the vertical deflection pulse is detected by IC201. Power supply
will shut down when waveform interval exceeds 2 seconds.
White Balance Failure If the RGB levels do not balance within 2 seconds after the power is turned on, this error will
be detected by IC201. The unit will stay on, but there will be no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Low B Error Occurs when set 5V is out.
Horizontal Deflection Stopped Occurs when either 1) a +B overcurrent is detected (IC5007) or 2) overheating is detected
(Thermistor TH5002).

After correcting the original service problem, perform the
following safety checks before releasing the set to the
customer:
1. Check the area of your repair for unsoldered or poorly
soldered connections. Check the entire board surface
for solder splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched”or touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground
straps, and mounting hardware have been replaced.
Be absolutely certain that you have replaced all the
insulators.
4. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer
and recommend their replacement.
6. Check the line cords for cracks and abrasion.
Recommend the replacement of any such line cord
to the customer.
7. Check the B+ and HV to see if they are specified
values. Make sure your instruments are accurate;
be suspicious of your HV meter if sets always have
low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
leakage. Check leakage as described below.
SAFETY CHECK-OUT
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 instructions.
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’s 250 and
Sanwa SH-63TRD are examples of passive VOMs that
are suitable. Nearly all battery-operated digital
multimeters that have a 2 VAC range are suitable
(see Figure A).
How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-
plate retaining screw on most AC outlet boxes is also at earth
ground. If the retaining screw is to be used as your earth
ground, verify that it is at ground by measuring the resistance
between it and a cold-water pipe with an ohmmeter. The
reading should be zero ohms. If a cold-water pipe is not
accessible, connect a 60- to 100-watt trouble- light (not a
neon lamp) between the hot side of the receptacle and the
retaining screw. Try both slots, if necessary, to locate the hot
side on the line; the lamp should light at normal brilliance if the
screw is at ground potential (see Figure B).
