1. Summary of Self-Diagnosis Function
• This device has a self-diagnosis function.
• In case of failure, the POWER/STANDBY or LAMP LED blinks or lights to assist service.
It is possible to specify the cause of the failure by the number of blink or the LED itself.
The following list shows the interpretation of those LED related information.
• For the failure hard to be reproduced, its record is stored at the internal NVM.
The record can be displayed with the remote commander to specify the cause of the failure.
2. Diagnosis and probable cause of Failure
• In case of failure, the POWER/STANDBY or LAMP LED blinks or lights to indicate the following diagnosis.
If two or more failures occurred at one time, the one occurred first will be indicated.
If they occurred simultaneously, the one corresponds to the fewer times of blink will be indicated.
• All the failure records listed below can be displayed on the screen.
“ 0 ” will be displayed when there is no failure record.

3. Blinking Sequence of POWER/STANDBY LED
4. Self-diagnosis screen display
• For the failure which is hard to reproduce, or accompany occasional power off and/or picture mute, the Self-diagnosis screen
display is useful to specify the cause.
<To show the screen display>
• Press the keys of the remote commander in rapid sequence as follows, when the set is in standby mode.
• One time blink is not used for self-diagnosis.
• Example
Diagnosis Times of LED blink
Lamp OFF :
3.0 sec
Lamp ON : 0.3 sec
Lamp cover 3 times
Fan 4 times
Lamp OFF : 0.3 sec
• Release of POWER/STANDBY LED blinking
The Self-Diagnosis function is released by unplugging the AC
cord temporarily.

5. Self-Diagnosis function operation
•3 : Lamp cover The rib at the back of the lamp cover closes the SW on T board to ground pin 3 of
CN8001.It’s monitored by the DE-micro (Pin 94 of IC6902) and turns off the lamp when
it’s open.
•4 : Fan Fan rotation is detected by “FAN-PROT”and the DE-micro (Pin 92 of IC6902) turns off the
lamp when it’s “high”.
•4 : Temp When the temperature sensor on the H3 board (WE) or H4 board (WF/XS) detects high
temperature or IIC-E line connector (CN6022:G2 board, CN44: H3/H4 board)is not sested
securely, DE-micro turns off the lamp.
•5 : Lamp driver When the “LAMP-PROT” (pin 95) is low, 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.
•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.
•9 : 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.
• LAMP : Lamp When the “LAMP-PROT” (pin 95) is low, lamp is not turned on.
If the “LAMP-HV-DET” (pin 96) is high at the same time, it is classified as no lamp or dead
lamp.
• The failure record is not automatically cleared.
So after repair, be sure to check the record and set it to “0” manually.
< To clear the failure record >
If the screen display is already on, the following step 1 and 2 can be skipped.
1. Power off (Set to the standby mode)
2. DISPLAY t Channel 5 t Vol - t POWER
3. Channel 8 t ENTER
< To clear the Self-diagnosis screen display >
• The self-diagnosis screen display is cleared by turning off the set with a remote commander or the power switch.
