SECTION 1
SELF DIAGNOSIS FUNCTION
The unit in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automatically begin to
flash.
The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER lamp 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.
1-1. DIAGNOSTIC TEST INDICATORS
When an errors occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem. If
there is more than one error, the lamp will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

1-4. SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible
to bring up past occurrences of failure for confirmation on the screen:
[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:

Numeral “0” means that no fault has been detected.
Numeral “1” means a fault has been detected.
Numeral “2” means two faults have been detected.
1-5. 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 button on the remote commander sequentially as shown below when the diagnostic screen is
being displayed.
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
Press “8” button
(It will indicate “CLEAR” on the screen.)
Press “-” button
(The “CLEAR” display change to red color.)

1-6. SELF-DIAGNOSTIC CIRCUIT
+B overcurrent (OCP) Occurs when an overcurrent on the +B (135 V) line is detected by Q6504.
If Q6504 go to ON, the voltage to pin 3 of IC001 go to UP. The unit will
automatically turn off.
+B overvoltage (OVP) Occurs when an overvoltage on the +B (135 V) line is detected by IC6502.
If IC6502 go to ON, then voltage to pin 6 of IC001 go to UP. The unit will
automatically turn off.
Vertical deflection failure Occurs when an absence of the vertical deflection pulse is detected by
Q8001 and D8001. Shut down the power supply.
White balance failure If the RGB levels do not balance or become low level within 5 seconds. This
error will be detected by IC4300.
TV will stay on, but there will be no picture.
High voltage protector of Horizontal Deflection Occurs when an overvoltage of horizontal pulse is detected by D8038 and
IC8006.
If the voltage of pin 1 of IC8006 goes to High, the voltage to pin 20 of
IC4300go to UP. The unit will automatically turn off.
Audio Protector If the Audio out lines become DC.This error will be detected by Q1211,
Q1209 and Q1210.
The unit will automatically turn off.

SET-UP ADJUSTMENTS
3-1. SCREEN VOLTAGE ADJUSTMENT
(ROUGH ALIGNMENT)
1. Receive the Monoscope signal.
2. Set 50% BRIGHTNESS and minimum PICTURE.
3. Turn the red VR on the focus pack all the way to the left and
then gradually turn it to the right until the point where you
can see the retrace line.
4. Next gradually turn it to the left to the position where the
retrace line disappears.
Fig. 3-1
3-2. SCREEN (G2) ADJUSTMENT
1. Turn on the power of the set.
2. Select VIDEO1 mode without signals.
3. Supply DC 175 ±0.5 V from external power supply to
TP7103 (KR), TP7203 (KG) or TP7303 (KB) of CR board,
CG board and CB board.
3. Adjust red, green and blue screen voltage to until retrace
line disappears with screen VR on the focus pack.
3-4. DEFLECTION YOKE TILT ADJUSTMENT
1. Receive the Monoscope signal.
2. Place the caps on the red and blue lens so that only the green
color.
3. Loosen the deflection yoke setscrew and align the tilt of the
Deflection yoke so that the bars at the center of the
monoscope pattern are horizontal.
4. After aligning the deflection yoke, fasten it securely to the
funnel-shaped portion (neck) of the CRT.
5. The tilt of the deflection yoke for red and blue is aligned the
same as was done for green.
