ERROR CODES
Error Codes, descriptions and corrective actions for the error are listed below:
* After 3 occurrences, the TV will be locked out and will not respond to Power On commands. After repair, use
the following procedure to unlock the TV.
1. Perform a System Reset by removing and re-applying AC.
2. Press and hold the side panel <INPUT> + <VOL

> buttons at the same time until the Status LED returns
to normal (about 5 seconds).
