Thanks for the info, just to clear, power light blinks once after every 4 seconds, is this correct?

Expert:  Shahid replied 1 year ago.

I guess I wasn't clear in above info-request.

When TV switch Off, do the power light on TV start flashing one time after every 4 seconds?

Expert:  Shahid replied 1 year ago.

Number of flashing power light is presenting an error code in TV and it will help me to troubleshoot the issue.

Tv turns off by itself then the blinking starts
Expert:  Shahid replied 1 year ago.

I understand, please count the blinks as how many times it blinks then pauses for 4 seconds and repeats the numbers of blinks again and post the info here, count the blink between 4 second pause to next 4 second pause.

It seems LED Board that drives the LED backlight inside panel, isn't working properly and causing the problem. Replacement of LED board will help to resolve the problem. Please click following board supplier link to view LED board image and price info to order it..
