Hello and Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.

- Have you tried to unplug TV and cable box power cords from wall outlet for 10 minutes to reset, replug back in, let cable box reboot that may take several minutes and check?
If not yet, can you try it now and reply back with the result?

Sorry to hear that, it seems power supply board failure, this board provides different voltage supplies to main board, replacement of power supply board in TV will help to resolve the problem. I would check standby volt (5V) output with multimeter on power supply board to confirm it, if no volts reading available then will swap the pwoer supply board and if standby 5V supply is available then it would be main board internal failure, main board board replacement is needed at this point.

Typing more info, give me 5 minutes please..

Expert:  Shahid replied 3 months ago.

If you have plan to do-it-yourself then check following board supplier to get required identical board (power or main board) as there are different type/ version of board utilized in this model..

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 approx $200 plus...
I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV. Please feel free to respond if you have any additional questions.

Electronics part can fail any time and most common reason is thunderstorm static charge or voltage fluctuation that sends caused surge volts and can damage the power regulator chips mounted on power supply board.

Circuit board replacement in this TV wouldn't be difficult for an average handy person, you can get help of any friend who knows/ have experience of electronics stuff repair to replace the bad board in TV which will save you tech labor to repair the TV is less amount. Board supplier link that I gave you in previous reply has boards on reasonable cost.

I hope these info will help, please feel free to respond if you have any additional questions.


PS: phone call assistance would cost you more money and may not help more than what I have already wrote down here in text chat format.
