First of all welcome to Justanswer. My name is Pramit. Before I start, have you tried unplugging the TV for 4-5 hours?
Follow the steps below and let me know the result. Pressing the front panel “INPUT”/"DEVICE" and “MENU” buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The ” Power LED” flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.
Note: The front panel buttons must 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 “34”, the LED will flash 3 times, pause, and then flash 4 times
