SUMMARY OF SELF-DIAGNOSIS FUNCTION
* This device includes a self-diagnosis function.
* In case of abnormalities, the TIMER/STANDBY indicator automatically blinks. It is possible to predict the abnormality location by the number of blinks. The Instruction Manual describes blinking of the TIMER/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.

Diagnosis Items and Prediction of Malfunction
Location
* When a malfunction occurs the TIMER/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.

{000
the range of values for number of operations is 000-255. For 256 or higher
there is no count up and the number remains at 255.}

Release of TIMER/STANDBY 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 confirmation.

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 standby state]
2. Press DISPLAY > CHANNEL (5) > VOLUME (+) >
POWER {Service Mode}
3. Press CHANNEL (8) > ENTER [Test reset = Factory
reset condition]
Method of Ending Self Diagnosis
When
ending the self-diagnosis screen completely, turn the power switch OFF on the
remote commander or the main unit.
Diagnosis Screen.
Self-diagnosis function operation
OCP >> Low B and +B line detect DET SHORT, and shut-down POWER ON RELAY.
Reset by turning power on/off.
In case of +B is loaded approx. 2A or more, microcomputer detects it via IC651.
OVP >> In case of +B becomes approx. 150V or more, POWER ON RELAY shuts down and microcomputer detects it via IC651.
Reset by turning power on/off just the same as OCP.
V Stop >> In case of microcomputer detects 2 seconds or more interval of V Pulse, Reference Pulse turns off by turning off the picture
signal in YC Jungle IC (IC206).
After the picture signal turns off, H Pulse is regenerated 2 seconds or more, the picture signal turns on.
AKB >> IK detection. Makes LED blinking in case of microcomputer doesn’t detect IK returns of IC206 CXA2147Q 30 seconds or more.
H Stop >> In case of HV becomes 33kV or more, IC502 detects it and shut-down H Drive Pulse.
Microcomputer receives H Stop data from IC206 and makes LED blinking.
Audio >> In case of DC component overlaps the output of Audio Amp., microcomputer detects it and makes LED blinking. Microcomputer forces to shut down the power.
OCP >> Low B and +B line detect DET SHORT, and shut-down POWER ON RELAY.
Reset by turning power on/off.
In case of +B is loaded approx. 2A or more, microcomputer detects it via IC651.
