SELF-DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER 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/TIMER 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/TIMER 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.
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:

+B overcurrent (OCP) Occurs when an overcurrent on the +B (135V) line is detected by pin 18 of IC355 (A Board).
If the voltage of pin 18 of IC355 (A Board) is less than 1V when V.SYNC is more than seven
verticals in a period, the unit will automatically turn off.
+B overvoltage (OVP) Occurs when the feedback circuit from +B opens IC643 or T603 (G Board)/IC6003 or PH6001
(GA Board) or any other associated feedback components.
V-STOP Occurs when an absence of the vertical deflection pulse is detected by pin 15 of IC355 (A
Board). Power supply will shut down when waveform interval exceeds 2 seconds.
IK(AKB) If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will
be detected by IC355 (A Board). TV will stay on, but there will be no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
NOTE:
Watch Dog Timer Indicates how many times the Watch Dog Timer functions have been activiated. Whenever
micro is reset by the Watch Dog Timer, this number is incremented. Maximum number is 255.

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).

REMOVAL PROCEDURES
HOW TO HANDLE AN ANODE CAP
WARNING: High voltage remains in the CRT even after the power is disconnected. To avoid electrical shock, discharge the CRT before
attempting to remove the anode cap. Short between anode and coated earth ground strap of CRT.
NOTE: After removing the anode, short circuit the anode of the picture tube and the anode cap to either the metal chassis, CRT shield,
or carbon painted on the CRT.
1
Do not use sharp objects which may cause damage to the
surface of the anode cap.
3
Do not force turn the foot of the rubber cover. This may cause
the shatter-hook terminal to protrude and damage the rubber.
2
To avoid damaging the anode cap, do not squeeze the rubber
covering too hard. A material fitting called a shatter-hook terminal
is built into the rubber.
2
Use your thumb to pull the rubber
cap firmly in the direction indicated
by arrow
b .
3
When one side of the rubber cap
separates from the anode button,
the anode cap can be removed by

5. Observe the screen and adjust SCREEN (G2) VR to obtain
the faintly visible background of dot signal.
6. Push the TEST + JUMP (+ Channel) to cut off the signal.
The screen should be bright or dark. Brightness of raster

7. Adjust screen VR until the screen is slightly cut off, or
scarcely lights up. A signal cannot be seen when the
brightness of the raster is high.

Preparation before Confirmation
1. Using a Variac, apply AC input voltage: 130+2.0/-0.0 VAC.
2. Turn the POWER switch ON.
3. Input a white signal and set the PICTURE and BRIGHT
controls to maximum.
4. Confirm that the voltage of more than 23.0 VDC appears
between TP85 and ground on theA Board.
Hold-Down Operation Confirmation
1. Connect the current meter between Pin 11 of the FBT
(T503) and the PWB land where Pin 11 would normally
attach (See Figure 1 above).
2. Input a dot signal and set PICTURE and BRIGHTNESS
to minimum: IABL = 2175 + 100/ -325 µA.
3. Confirm the voltage of A Board TP91 is 135 ± 1.5 VDC.
4. Connect the digital voltmeter and the DC power supply to
TP85 and ground. (See Figure 1 above).
5. Increase the DC power voltage gradually until the picture
blanks out.
6. Turn DC power source off immediately.
7. Read the digital voltmeter indication
(standard = 27.24 + 0.0/ - 0.1 VDC).
8. Input a white signal and set PICTURE and BRIGHTNESS
to maximum: IABL = 2175 + 100/ -325 µA.
9. Repeat steps 4 to 7.
