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

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.
