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.
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>
<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.
˘
Be aware that this differs from the method of
entering the service mode (volume + ).

6. 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. 1.5A or more, microcomputer detects it via IC6102.
OVP
In case of +B becomes approx. 150V or more, POWER ON RELAY shuts down and microcomputer detects it via IC6102.
Reset by turning power on/off just the same as OCP.
V Stop
In case of V Drive disappeared, Q5005 detecs it and shut-down POWER ON RELAY. Microcomputer detects it and makes LED
blinking.
AKB
IK detection. Makes LED blinking in case of microcomputer doesn’t detect IK returns of IC511 (CXA2101AQ) 30 seconds or
more.
H Stop
In case of H DRIVE is disappeared, Q5006 detects it and shut-down POWER ON RELAY shuts down.
Microcomputer receives H Stop data from Q5006 and makes LED blinking.
HV Stop In case of HV becomes 33KV or more. IC8006 and IC8010 detect it and shut-down
POWER ON RELAY. Microcomputer makes LED blinking.
Audio
In case of DC component overlaps the output of Audio Amp., POWER ON RELAY shuts down.
Microcomputer detects it and makes LED blinking.
