DIAGNOSTIC TEST INDICATORS
If there is more than one error, the LED will identify the first of the problem areas. Result for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred .

SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to bring up past occurrences of failure for confirmation on the screen:
To Bring Up Screen Test
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:
To Bring Up Screen Test
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:
DISPAY > CHANEL5 > VLOUME + > POWER
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen. After you have completed the repairs, clear the result display to “0”.
Quitting Self-diagnostic screen
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
