SELF DIAGNOSTIC FUNCTION .......................................4
The units 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.DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY/TIMER lamp will flash a 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 occured if the screen displays a “0”.

Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER lamp
from flashing.
4. SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes off ” that cannot be confirmed, it
is possible to bring up past occurances 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:
[Screendisplay] / channel [5] / Sound volume [-] / Power ON
˘
Note that this differs from entering the service mode (mode volume [+]).

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 buttons on the remote commander sequentially as shown below when the diagnostic
screen is being displayed.
Channel [8] / 0
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

[+BovercurrentªOCPº]Occurs when an overcurrent on the +B(135) line is detected by Q6610
and Q6609.
If Q6610 and Q6609 go to ON, the voltage to the pin3 of IC001 go to UP.
The unit will automatically turn off.
[+BovervoltageªOVPº]Occurs when an overvoltage on the +B(135) line is detected by D6635
and Q6611. If Q6611 go to ON, the voltage to pin6 of IC001 go to UP. The
unit will automatically turn off.
[Verticaldeflectionfailure]Occurs when an absence of the vertical deflection pulse is detected by
Q6819 and R6832. Shut down the power supply.
[Whitebalancefailure]If the RGB levels do not balance or become low level within 5 seconds.
This error will be detected by IC4301.
TV will stay on, but there will be no picture.
[HighvoltageprotectorofHorizontalDeflection]Occurs when an overvoltage of horizontal pulse is detected by D6809 and
IC6801.
If the voltage of anode D6830, Q6800 and D6825 goes to High, the
voltage to pin34 of IC4301 go to UP. The unit will automatically turn off.

• REMOVAL OF ANODE-CAP
Note:
• After removing the anode, short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT
shield or carbon paint on the CRT.
•REMOVING PROCEDURES

1 Turn up one side of the rubber cap in the direction
indicated by the arrow a.
b
b
2 Using a thumb pull up the rubber cap firmly in the direc-
tion indicated by the arrow b.
c
Anode Button
3 When one side of the rubber cap is separated from the
anode button, the anode-cap can be removed by
turning up the rubber cap and pulling it up in the
direction of the arrow c.
•HOW TO HANDLE AN ANODE-CAP
1 Do not damage the surface of anode-caps with
sharp shaped objects.
2 Do not press the rubber too hard so as not to
damage the inside of anode-cap.
A metal fitting called the shatter-hook terminal is
built into the rubber.
3 Do not turn the foot of rubber over too hard.
The shatter-hook terminal will stick out or damage
the rubber.

ADVANCE OPERATION
4-1. "RESET" FUNCTION
1. Purpose
If a customer faces some setting problem that cannot be solved, using the "RESET" function some items will be
reset to its original setting (shipping condition)
2. How to Operate
There are 2 ways to access to the "RESET" Function:-
a) By pressing "RESET" button on the Remote Commander.
b) By pressing "MENU" button on the Front Key Input and hold it down for 5 seconds.
3. Subsequent of Operation
Sequential to the resetting operation (either methods being used in No. 2), TV set would shut down once and
automatically turn on again. The power-off duration is expected to be about 500msec. An OSD message,
"RESET" tentatively will be displayed for 10 sec after IK status gets stable.
As a result, some items will be reset to an initial condition (shipment condition) wheareas some other remains at
the last selection by user.

2. Position neck assy as shown in Fig 5-1.
3. Set the pattern generator raster signal to a green raster.
4. Move the deflection yoke to the rear and adjust with the
purity control so that the green is at the center and the blue
and the red take up equally sized areas on each side.
(See Figures 5-1 through 5-3.)
5. Move the deflection yoke forward and adjust so that the
entire screen is green. (See Figure 5-2.)
6. Switch the raster signal to blue, then to red and verify the
condition.
7. When the position of the deflection yoke has been decided,
fasten the deflection yoke with the screws and DY spacers.
8. If the beam does not land correctly in all the corners, use a
magnet to adjust it.
