LED BLINKING ERROR CODE AND DESCRIPTION 

SELF DIAGNOSIS FUNCTION

If an error occurs, the STANDBY LED will automatically begin to flash.
The number of times the LED flashes translates to a probable source of the problem.
A definition of the STANDBY LED flash indicators is listed in the instruction manual for the user’s knowledge and reference.
If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.

DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY LED will flash a set number of times to indicate the possible cause of the problem. 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:

INFORMATION >NUMBER BUTTON 5 > VOLUME - > TV STANDBY

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”.
Clearing the result display
To clear the result display to “0”, press button on the remote commander sequentially as shown below when the diagnostic screen is being displayed.
<Delection of Error Count and Error History>
Press “8” button , Press “0” button
<Delection of Panel Operation Time>
Press “7” button , Press “0” button
Quitting Self-diagnostic screen
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
