KP-FR43M31/FR43M91
RM-GA001
The unit in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically
begin to flash.
The number of times the LED flashes translates to a probable source of the problem. A defination of the STANDBY/TIMER
LED flash indicators is listed in the intruction 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.
1-1. DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY/TIMER LED will flash a number of times to indicate the possible cause of the
problem. If there is more than one error, the LED will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred.
SECTION 1
SELF DIAGNOSTIC FUNCTION
*If a +B overcurrent is detected, stoppage of the vertical detection is detected simultaneously. The symptom that is
diagnosed first by the microcontroller is displayed on the screen.
** Refer to screen (G2) adjustment (fine adjustment) in section 2 of this manual.
*** Is STANDBY/TIMER LED flashes six (6) times, unplug the unit and wait 10 seconds before performing the adjustment.

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.
1-4. 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 occurrences 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:
+B Overcurrent 2 tims
Low +B Overvoltage 3 tims
Vert deflection stopped 4 tims
White balance failure 5 tims
Low +B OVP/OCP 6 tims
Horiz. deflection stopped 7 tims
Audio protection 8 tims
Zero crossing detector 9 tims
HV protection 10 tims

*: Note that this differs from entering the service mode
(volume +)
Since the diagnostic results displayed on the screen are
not automatically cleared, always check the self-
diagnostic screen.
After you have completed repairs, clear the result display
to “0”
[Clearing the result display]
To clear the result display to “0”, press button on the remote
commander sequentially as shown below when the
diagnostic screen is being displayed.
Press 8button
(It will indicate “CLEAR” on the screen.)
Press -button
(The “CLEAR” display change to red color.)
[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 excessive current flows through R6812.
The increase in voltage across Q6803 causes it to turn on which sends a high
signal to the micro.
+B overvoltage (OVP) IC6801 detects +B OVP condition and Q6802.
This sends a high signal to the micro and also shuts down the AC relay.
V-STOP Occurs when an absence of the vertical deflection pulse is detected by pin 56
of IC0404. (MG board)
Power supply will shut down when waveform interval exceeds 2 seconds.
While balance failure If the RGB levels* do not balance within 2 seconds after the power is turned
on, this error will be detected by IC0401.
TV will stay on, but there will be no picture.
Low +B OCP/OVP Occurs when set 5V is out.
Horizontal deflection stopped Occurs when either:
1) a +B overcurrent is detected (Q6803), or
2) IC0401 (MG board) is damaged.
