13 times then pause
Expert:  Shahid replied 1 year ago.

Thanks for the info.

13 times flashing power light indicates 'balancer' error and backlight inverter board would have got internal issue.

Have you tried to unplug TV power cord from wall outlet for 10 minutes to reset, replug back in and check, if problem persist then backlight inverter board or DF1 board could be defective and swapping it will help to resolve the problem.

Please check following board supplier link to get required board if you wish to replace it in TV by yourself..

If you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote...

I trust my input will help you out. Please feel free to respond if you have any additional questions.
