SELF DIAGNOSTIC FUNCTION
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. 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”.

[+B overcurrent OCP ]Occurs when an overcurrent on the +B(135) line is detected by Q6804.
If Q6804 go to ON, the voltage to the pin57 of IC4301 go to "HIGH".
The unit will automatically turn off.
[High voltage protector of Horizontal Deflection]Occurs when an overvoltage of horizontal pulse is detected by D6809.
If the voltage of anode D6809 and D6843 goes to High, the voltage to pin57
of IC4301 go to "HIGH".
The unit will automatically turn off.
[+B overvoltage OVP ]Occurs when an overvoltage on the +B(135) line is detected by D6635 and
Q6606. If Q6606 go to ON, the voltage to pin6 of IC001 go to "HIGH". The
unit will automatically turn off.
[Vertical deflection failure]Occurs when an absence of the vertical deflection pulse is detected by
Q6808 and R6910. Shut down the power supply.
[White balance failure]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.
[5V/9V failure]Occurs when 5V/9V is not supplied to Micon (IC001).
No raster will be detected or no picture.

• 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.
RM-GA002
•REMOVING PROCEDURES
a
a
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 direction
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.

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) colomn, the data after the slash mark ("/") refers to NTSC model data.
No ("/") means data is common for Multi and NTSC model.
b) Item remarked "*", please refer page 27 for the data.
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.
