The units in this manual contain a self-diagnostic function. If an error occurs, the
/STANDBY or
LED will automatically begin
to flash.
The number of times the LED fl ashes translates to a probable source of the problem. A defi nition of the
/STANDBY or
LED
flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom is diffi cult to reproduced
use the Remote
Commander to display the record that is stored at the internal NVM to specify the cause of the failure.
Diagnostic Test Indicators
When an error occurs, the
/STANDBY or
LED will fl 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 fi rst of the problem areas. If the errors occur simultaneously, the one that
corresponds to the fewest flashes is identifi ed fi rst.
Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

Self-Diagnosis Screen Display
For failures that are diffi cult to reproduce, or accompany occasional power off and/or picture mute, the Self-Diagnosis screen display is
useful to specify the cause.
To Bring Up Screen Test
In standby mode, press the buttons on the Remote Commander sequentially, in rapid succession, as shown below:

"1" is displayed when a failure is detected one or more times
"0" is displayed when no failure has been detected
"0" is displayed when no failure has been detected
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs.
When you have completed the repairs, clear the result display to “0”.
Note: The self-diagnostic function will not be able to detect any subsequent faults after completion of the repairs unless the result
display is cleared to “0”.

3 :
Lamp cover
The rib at the back of the lamp cover closes the SW on the T board to ground pin 3 of
CN8001.
It is monitored by the DE-micro (pin 94 of IC6902) and turns off the lamp when it is opened.
4 :
Fan
Fan rotation is detected by “FAN-PROT” and the DE-micro (pin 92 of IC6902) turns off the
lamp when it is “high”.
4 :
Temp
When the temperature sensor on the H3 board (WE models) or H4 board (WF/XS models)
detects high temperature, or IIC-E line connector (CN6022:G2 board, CN44:H3board/
H4board) is not seated securely, the DE-micro turns off the lamp.
5 :
Lamp driver
When the “LAMP-PROT” (pin 95) is low, the lamp is not turned on. If the “LAMP-HV-
DET”(pin 96) is low at the same time, it is classified as no high voltage of the lamp driver.
6 :
Low B error
When no “DD 6V “ is detected, pin 129 of TV-micro is low and it turns off the main power.
7 :
Audio
When DC voltage is detected at the speaker or woofer outputs, pin 128 of TV-micro is low
and it turns off the main power.
8 :
D-OVP
When overvoltage of “+3.3V” or “+2.5V” is detected, pin 126 of TV-micro is low and it
turns off the main power.
10 :
ATSC-OVP
When no “Digital Module 5V” is detected, pin 127 of TV-micro is low and it turns off the
main power.
LAMP :
Lamp
When the “LAMP-PROT” (pin 95) is low, the lamp is not turned on. If the “LAMP-HV-
DET” (pin96) is high at the same time, it is classified as no lamp or a dead lamp.
Clearing the Result Display
To clear the result display to “0”, press the buttons on the Remote Commander sequentially when the diagnostic screen is displayed, as
shown below:
1. If the screen is already displayed, proceed to step 3. If not, Power off (Set to Standby model).
