SECTION 1
SELF DIAGNOSIS FUNCTION
1. Summary of Self-Diagnosis Function
• This device includes a self-diagnosis function.
• In case of abnormalities, the STANDBY/STEREO indicator automatically blinks. It is possible to predict the abnormality location
by the number of blinks. The Instruction Manual describes blinking of the STANDBY/STEREO 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 STANDBY/STEREO 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.
3. Blinking count display of STANDBY/STEREO indicator
* One blink is not used for self-diagnosis.

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.
<Screen Display Method>
• Quickly press the remote command button in the following order from the standby state.

Numeral “0” means that no fault
was detected.
5. 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 standby mode)
2. DISPLAY b Channel 5 b VOL + b POWER (Service Mode)
3. Channel 8 b 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.

detects it and make turn off the lamp.
4 : FAN StopWhen FAN1 or FAN2 is stopped then pin 8 or q; of CN1908 on the A board is high, LCD Engine µ-com
(IC9502) detects it and make turn off the lamp.
5 : Lamp DriverWhen lamp is not turned on then pin wl of LCD Engine µ-com (IC9502) is high, checks pin wk of LCD Engine
µ-com . If pin wk is low, it is judged no High Voltage.
6 : Low BDetect +5 V line failure.
9 : AudioWhen DC is appeared by audio amp failure at speaker line.
Then it is detected by MAIN µ-com (IC9004) and it turns off the main power.
LAMP : Lamp errorWhen lamp is not turned on then pin wl of LCD Engine µ-com (IC9502) is high, checks pin wk of LCD Engine
µ-com. If pin wk is high, it is judged lamp is burned out.
