SELF DIAGNOSTIC FUNCTION
The units in this manual contain a self diagnostic function. If an error occurs, the STANDBY (1) indicator will automatically
begin to flash. A description of the self-diagnosis function is explained in the operating instructions. The number of times
the STANDBY (1) indicator flashes translates to a probable source of the problem. 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 (1) indicator will flash a set number of times to indicate the possible cause of the
problem. If there is more than one error, the indicator will identify the first of the problem areas.
Result for all of the following diagnosis items are displayed on screen. No error has occured if the screen displays a "0".

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 occurrence of failure on the screen for confirmation.
[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:

5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY
Since the diagnosis 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-diagnosis 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 self-diagnostic screen is
displayed, as shown below:
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.

[+B overcurrent OCP ]Occurs when an overcurrent on the +B (135V) line is detected by pin 97 of IC001
(A Board). If the voltage of pin 97 of IC001 (A Board) is less than 3.9V, the unit will
automatically go to standby.

IC001 (A Board).
[IK $AKB%]If the RGB levels* do not balance within 15 sec after the power is turned on, this error
will be detected by IC001 (A Board). TV will stay on, and indicator will start to Blink 5
times.
[Supply Voltage Protection]Occurs when IC001 internal Supply Voltage Protection detects less than 4.2V due to
unproper power supply to IC001. TV cuts off high voltage power of anode CRT. No
picture will be detected eg IC607, IC604 go faulty.

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.

H.STAT variable resistor and the V.STAT magnet in the
manner given below.
(In this case,the H.STAT variable resistor and the
