SELF-DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to ash. The number
of times the LED ashes translates to a probable source of the problem. A denition of the STANDBY/TIMER LED ash 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.
Diagnostic Test Indicators
When an error occurs, the STANDBY/TIMER LED will ash 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 rst of the problem areas.
Results for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred.

Release of TIMER STAND BY indicator blinking
The TIMER/STANDBY indicator blinking display is released by turning OFF the power switch on the TV main unit or removing the plug from the power.
Self-Diagnosis Screen Displays
In cases of malfunctions where it is not possible to determine the symptom such as when the power goes off occasionally or when the screen
disappears occasionally, there is a screen display on whether the malfunction occurred or not in the past (and whether the detection circuit operated or
not) in order to allow conrmation.
Screen Display Method
Quickly press the remote command button in the following order from the standby state.
Display Channel 5 Sound Volume* _ Power ON
*Note that this differs from entering the service mode (sound volume + )
Numeral “0”
means that no fault was detected.
Numeral “1”
means a fault was detected one
time only.

Self-Diagnosis Screen Display
The results display is not automatically cleared. In case of repairs and after repairs, check the self-diagnosis screen and be sure to return the results
display to “ 0 ”.
If the results display is not returned to “ 0 ” it will not be possible to judge a new malfunction after completing repairs.
Method of Clearing Results Display
1. Power off (Set to the stand by mode.)
2. Display Channel 5 Sound Volume + Power ON (Service Mode)
3. Channel 8 ENTER (Test reset = Factory preset condition)
Method of Ending Self Diagnosis Screen
When ending the self-diagnosis screen completely, turn the power switch OFF on the remote commander or the main unit.

Self-Diagnosis Function Operation
+B overcurrent (OCP)
Occurs when excessive current ows 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 turns on 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 deection pulse is detected by pin 56 of IC0401 (MA 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.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Low B OCP/OVP
Occurs when set 5V is out.
Horizontal Deection Stopped
Occurs when either:
1) a +B overcurrent is detected (Q6803), or
2) IC0401 (MA Board) is damaged.

2-15.AUTO REGISTRATION ERROR CODES
If an error code is displayed after the set has been correctly adjusted, check the following items: position, tilt and sizing. If any of these adjustments
are off, even slightly, the auto-registration pattern will not hit the four sensors properly. This occurs when the internal generator patterns are being
ashed on the screen for the sensors to read. Therefore, auto registration (called auto convergence) cannot operate properly, causing an error code to
be displayed. In order for this function to operate properly, position, tilt and size must be adjusted properly.
