3. Error Code Operational Check

Note: The TV must be in “Shut Down” and not have been switched Off, to perform the Error Code Opera-

tional Check. When the TV is switched Off, the code automatically resets to “12” No Error.

Pressing the front panel “DEVICE” and “MENU” buttons at the same time, and holding for 5 seconds, activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem has occured since the last Initalization.

Note: The front panel buttons must be used, NOT those on the Remote Control.

The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

The flashing then pauses for approximately 1/2 second.

The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

The Error Code is repeated a total of 5 times.

Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
