SELF DIAGNOSIS FUNCTION
The units in this manual contain a self diagnosis function. If an error occurs, the STANDBY (1) indicator will automatically
begin to flash. The number of times the STANDBY (1) indicator flasher 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.DIAGNOSIS 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 1V when V.SYNC is
more than HV, the unit will automatically go to standby.
[I-Port]Occurs when an absence of the vertical deflection pulse is detected by pin 116 of
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 indicalor will start to Blink 5

[HV Protect]Occurs when IC001 internal HV protect detects an abnormal. H-Pulse (frequency) due
to unproper power supply to IC001. TV cuts off high voltage power of anode CRT. No

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.
