Hello, I'm Shahid and will be happy to assist you. I need additional info to troubleshoot the issue.

Flashing red light indicates failure inside TV, can you please follow the below procedure to get error code from TV that will help to troubleshoot the problem?

Please press the front panel ACTIVITY + CH Down buttons at the same time and hold for 5 seconds. The STATUS LED will then flash denoting a two digit code.

Example: If the Error Code is “23”, the LED will flash two times, pause, and then flash three times.

What error code you get from TV?

Shahid is there anything else that I can try or have the technician try as I am just not seeing any codes when I hold the activity and CH down button. Thanks
Expert:  Shahid replied 1 year ago.

I'm afraid there is no other way around, does the status light blink in same way after holding down two buttons on TV front panel?
