LED Indicator Diagnostics

The front panel LEDs provide an indication of the set's operation, and the possible cause of a malfunction. There are three
front panel LEDs, "Power", "Status" and "Lamp". The LED display shows the current status or indicates a possible
malfunction.

* A red Lamp LED only occurs after 3 attempts to light the lamp.
Each attempt (pressing POWER) must be at least 65 seconds apart. .
During each attempt ballast striking may be audible.

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 "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The "TIMER LED" flashes denoting a two digit Error Code, or indicating no
problem has occurred since the last Initialization.
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 "23", the LED will flash two times, pause, and then flash three times.

    The manual should describe what's actually going wrong and list probable causes. My timer light is constantly blinking. I don't see that on the error codes page here, which makes it hard to figure out what error code I'm getting
