4. LED Indicator Diagnostics

The “Power ON LED” provides an indication of the sets operation, and the possible cause of a malfunction.

1.Initial Control Circuitry Check

Immediately after the TV is connected to an AC power source:

The LED flashes three times ... indicating the Microprocessor has initialized and is functioning properly.

If the LED does not flash ... the Microprocessor is NOT functioning.

2.Error Code Operational Check

Pressing the front panel “INPUT” 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.

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 “24”, the LED will flash two times, pause, and then flash four times.
