SELF DIAGNOSTIC FUNCTION ................................... 4
1. GENERAL ................................................................. 7
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 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 occured if the screen displays a “0”.

Detected
Symptoms
• Power does not come on.
• No power is supplied to
the TV.
• AC power supply is faulty.
• Power does not come on.
• Load on power line is
shorted.
• Has entered standby state
after horizontal raster.
• Power line is shorted or
power supply is stopped.
• Vertical deflection pulse
is stopped
• Power is shut down
shortly, after this return
back to normal.
• Detect Micro latch up.
Note 1: If a + B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously.
The symptom that is diagnosed first by the microcontroller is displayed on the screen.
Note 2: Refer to screen (G2) Adjustment in section 3-4 of this manual.

3. STOPPING THE STANDBY/TIMER FLASH
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 out” 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 Q500. If Q500 go to
ON and the voltage to pin 50 of IC301 more than 3.5V when V.SYNC is more than
seven verticals in a period, the unit will automatically turn off.
[Verticaldeflectionstopped]Occurs when an absence of the vertical deflection pulse is detected by Pin 17 and
IC001 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 IC301. TV will stay on, but there will be no picture.
* (Refers to the RGB levels of the AKB detection Ref pulse that detects IK.)

2. Set the pattern generator raster signal to a green raster.
3. 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 3-1 through 3-4.)
4. Move the deflection yoke forward and adjust so that the
entire screen is green. (See Figure 3-1.)
5. Switch the raster signal to blue, then to red and verify the
condition.
6. When the position of the deflection yoke has been decided,
fasten the deflection yoke with the screws and DY spacers.
7. If the beam does not land correctly in all the corners, use a
magnet to adjust it.
