SELF DIAGNOSIS FUNCTION
1. Summary of Self-Diagnosis Function
- This device includes a self-diagnosis function.
- In case of abnormalities, the POWER/STANDBY indicator automatically blinks. It is
possible to predict the abnormality location by the number of blinks. The Instruction
Manual describes blinking of the POWER/STANDBY indicator.
- If the symptom is not reproduced sometimes in case of a malfunction, there is recording of
whether a malfunction was generated or not. Operate the remote command to confirm the
matter on the screen and to predict the location of the abnormality.
2. Diagnosis Items and Prediction of Malfunction Location
- When a malfunction occurs the POWER/STANDBY indicator only blinks for one of the
following diagnosis items. In case of two or more malfunctions, the item which first
occurred blinks. If the malfunctions occurred simultaneously, the item with the lower
blink count blinks first.
- The screen display displays the results regarding all the diagnosis items listed below.
The display "0" means that no malfunctions occurred.

- One blink is not used for self-diagnosis.
- Example
Diagnosis item LED blinks
Lamp cover 3 times
Fan 4 times

LED OFF : 0.3sec LED OFF
3.0sec
- Release of POWER/STANDBY indicator blinking
The POWER/STANDBY indicator blinking display is released by removing the plug from
the power or leaving for 2 minutes.
4. 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 confirmation.
- Quickly press the remote command button in the following order from the standby state.

- 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.

- 3 : Lamp cover When lamp cover SW is opened then pin 1 of CN8034 on the A
board is high, LCD Engine u-com (pin 27 of IC3208 on the C2
board) detects it and make turn off the lamp.
- 4 : Fan When Fan1 or Fan2 or Fan3 or Fan4 is stopped then pin 2 or 5
or 8 or 11 of CN8035 on the A board is high, LCD Engine u-com
(pin 24 of IC3208 on the C2 board) detects it and
make turn off the lamp.
- 4 : Temp When a temperature sensor on the H4 board detects a high
temperature or IIC-E line connector (CN8041:A board,CN3951
H4 board) is not attached securely, LCD Engine u-com IIC-E
Line detects it and make turn off the lamp.
- 5 : Lamp driver When lamp is not turned on then pin 29 of LCD Engine u-com
(IC3208 on the C2 board) is high, checks pin 28 of LCD Engine
u-com. If pin 28 is low, it is judged no high voltage.
- 6 : +B OVP When +17V line drop then pin 53 of MAIN u-com (IC3405 on the
C2 board) is low, it turns off the main power.
- 7 : Audio When DC is appeared by audio amp failure at speaker line.
Then it is detected by MAIN u-com (pin 59 of IC3405 on the C2
board) and it turns off the main power.
- 8 : D-OVP When +3.3V or +2.5V or +1.8V line over then pin 49 of MAIN
u-com (IC3405 on the C2 board) is low, it turns off the main
power.
- LAMP : Lamp When lamp is not turned on then pin 29 of LCD Engine u-com
(IC3208 on the C2 board) is high, checks pin 28 of LCD Engine
u-com. If pin 28 is high, it is judged lamp is burned out.
