SELF DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY Indicator will automatically
begin to flash.
The number of times the STANDBY 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 error occurs, the STANDBY Indicator will flash a 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 diagnostic items are displayed on screen. No error has occured if the screen displays a “0”.

[+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 more than 4V, the unit will automatically go to
standby.
[V-PROTECT]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, but there will be 5 times LED blinking.
POWER SUPPLY NG (+5V)
for VIDEO PROCESSOR
Occurs when IC001 internal HV protect detects an abnormal H-Pulse (frequency) due to
improper power supply to IC001. TV cuts off high voltage power of anode CRT. No picture will be
detected. eg: IC602, IC604 go faulty.
* (Refers to the RGB levels of the AKB detection Ref pulse that detects IK.)

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

2 Using a thumb pull up the rubber cap firmly in the direc-
tion indicated by the arrow b.

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.

Note : 1. In [WRITE], the data for all items are written into memory together.
2. For adjustment items that have different standard data between 50Hz or 60Hz, be sure to use the respective input
signal after adjustment.
a) In the initial value (detailed) column, the data after the slash mark ("/") refers to NTSC model data.
No ("/") means data is common for Multi and NTSC model.
b) Item remarked "*" and "**", please refer page xx ~ xx for the data (not applicable for these models).
c)
shaded items are no data.
d) Standard data listed on the Adjustment Item Table are reference values, therefore it may be different for each model and for each mode.
e) Note for the Different Data those are the standard data values written on the microprocessor. Therefore, the data values of the models are stored respectively in the memory.
In the case of a device replacement, adjustment by rewriting the data value is necessary for some items.
