SECTION 1
SELF DIAGNOSIS FUNCTION
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 definition of the STANDBY/TIMER LED flash
indicators is listed in the instruction 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 set 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 .

•+B overcurrent

•+B overvoltage

diagnosed first by the microcontroller is displayed on the screen.
** Refer to screen (G2) adjustment (fine adjustment) in section 2 of this manual.

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:

* : 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 the 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.
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
Press “8”button
(It will indicate “CLEAR”on the screen.) Press “-”button
(The “CLEAR”display change to red color.)

+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.
White 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.
