DIAGNOSIS INFORMATION

--- : LED off Orange : Both Red and Green light

Red flash N :

The cycle that Red flashes N times and goes out for fixed time is repeated.

LED Error Indication List

Outline of self-diagnosis function

This product is provided with the self-diagnosis function. In case of any abnormality, the LED at the top of the product will

indicate the errors. There are 2 ways for diagnosis.

1Connect a personal computer to the product. Then, input [00~CHK] from the hyper-terminal window of the personal

computer during stand-by.

2Connect a personal computer and click the “diagnosis” button of PCGC, the diagnostic software to read the warning

history.

Note: Diagnosis can be 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 the above-

mentioned way normally.

Diagnosis result indication

LED indication and failures are shown in the following table. LED can be reset “automatically” or “by turning on/off of the main

power” when the fault detection is finished.

be displayed. Select the model you want to use and press

the OK button to display the main dialog window. Press the

Cancel button to exit this application.

(2) Main dialog window

1. The main dialog window displays the information stored

in the projector (model name, serial No., software

version, etc.) and the service menu information.

Information displayed in this window depends on the

selected models.

port. In such cases, press the Change COM PORT

button to switch the COM port. Refer to (4) Switching

the COM port.

3. Press any of the Warning Status, Warning History 1,

Warning History 2, or Warning History 3 button to

display the warning dialog window containing the

detailed error data.

4. Press the DIAGNOSIS button to start self-diagnosis.

(Self -diagnosis isn’t available during power-on or when

an error occurs.)

Warning Status : The current warning status is displayed.

The data will disappear after the error is

corrected.

Warning History 1

: The latest warning history data are

recorded in the Warning History 1. The

data remains after the error is corrected.

Warning History 2

: The second oldest warning history data

are recorded in the Warning History 2.

Warning History 3

: The oldest warning history data recorded

in the Warning History 3.

Note: When the power is turned off because of an error, the

warning history data are recorded. That is, only when

an error occurs during power on or when an error is

detected during self-diagnosis (or immediately after

the DIAGNOSIS button is pressed), the warning

history data are recorded. (The warning history data

aren’t recorded when the stand-by power fails during

the stand-by mode. In this case, LED warning

indication will appear and you can check the error

data by the Warning Status.)
