DIAGNOSIS INFORMATION
Outline of self-diagnosis function
This projector is provided with the self-diagnosis function. In case of any failure, the LED at the top of the projector will indicate
the failure. There are two ways for diagnosis.
1. Connect a personal computer to the projector. Then, input [00~CHK] from the hyper-terminal window of the personal com-
puter during stand-by.
2. Connect a personal computer and click the “diagnosis” button of PCGC, the diagnostic software to read the warning history.
Note: Diagnosis can be also carried out by turning on the main power and then turning on the power of the operation panel.
However, as the diagnosis items are different and it may cause a secondary failure, carry out the diagnosis in either of
the above-mentioned ways in most cases.
Diagnosis result indication
LED indication and failures are described in the following table. LED can be reset “automatically” or “by turning on/off of the
main power” after the failure is corrected.
