TV keeps turning on and off.

Hi everyone,

My Samsung tv gets stuck in a loop of turning itself on and off and I can’t even get it to turn on now. I’ve had some Samsung tvs have capacitor issues but I’ve taken the back off the tv to have a look at the new pcbs and they look fine.  I’ve attached the pictures.

any help would be appreciated.

Maybe either the system 8s corrupted or Maybe your Hardware unit might be faulty. If it's a newer Samsung TV Either with or out of warranty I suggest that u contact Samsung. If it's an very old Samsung TV Like before 2016 or 2017. Idk if Samsung is going to help with that

Check that all your cables are securely connected and there is no issue there.  check  if you have the latest firmware as suggested in the article, You have not named the model but can check on the Samsung support site and download to USB if applicable and see if you are able to update https://www.samsung.com/uk/support/   If fine there  I would suggest slightly different advice in  disconnecting all cables and switching off the mains for around 10 minutes, if the soft Reset mentioned does  not work.   Afterwards reconnect and see if the issue is resolved.

Well fist things first, make sure the power cord matches the tv. Required amp and wattage. You'll find the cord information running up and down the cord. If not it should be on either end 

 Second you have the wrong front panel service menu bytes incorrect.

Third, I'm assuming you turned off watchdog because you got paranoid and turned it off without realizing it's meant for errors in both the hardware and software of the tv
