Samsung LED Smart TV keeps turning off and on

JUMP TO SOLUTION

I have a 60 inch Samsung LED Smart TV that I got from Costco about a year ago, it's worked perfectly up until today.  I was watching some recipe videos on YouTube, when all of a sudden it starts turning off and on, it's been doing the same thing for the past 4 hours

Hey there, try the following Smiley Happy

 

By default, some HDMI devices are set to turn the TV on when they turn on. This feature is Anynet+, also known as HDMI-CEC, and allows you to control both devices with your TV remote. If you want to turn on your devices separately, you can turn off Anynet+ in Settings > General > External Device Manager, but you will no longer be able to use your TV remote for both devices.

 

Unplug the TV for 30 seconds.

Unplug the TV from the wall outlet or surge protector for 30 seconds, and then plug it back in.

 

Try to update the software.

In some cases, a software update can correct the problem. There is a risk, however. If the TV turns off during the software update, it could damage the TV. Updates can take up to 30 minutes depending on network speed, so if the TV is not turning off too frequently, try updating the software.

 

Disable the Power On with Mobile option.

TVs that can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on.

If you do not want this function, navigate to Settings > General > Network > Expert Settings > Power On with Mobile, and turn the setting off.

 

If the above troubleshooting steps didn't help, here are some service options:

- If your unit was recently purchased, you can check with your retailer on their return/exchange processes.

- If you have an extended warranty you can reach out to them to have service processed.

- If you're within the one year warranty, you can Private message one of our moderators to have service processed.

- If you're OUT of warranty, you the following link to locate a service center in your area by using the link below

Try unplugging the TV for a few minutes before trying it again. That should reset it and fix the issue.

Just a quick update, when I got home from work, almost 8hrs ago, I plugged it in, after it being unplugged for 12 hours, and nothing, still the same problem, it is currently unplugged since then

 

And it was plugged into the wall prior to all this trouble

After unplugging your TV and letting it set for a few minutes to purge itself and reboot, about 5 minutes, try rebooting your cable box. It worked for me, so far.

My 32” Samsung Smart TV model UN32F5500AF keeps turning off and on no matter how many times you hard reset it, unplug it, plug into a different electrical outlet, etc. (all suggested to me by Samsung support). I am shocked by how Samsung has begun to screw its customers. I have owned many Samsung TVs in the past, but I will never purchase another. Paid a high price for a throw-away TV (can’t bear to think of all these junk TVs being thrown into landfills each day as they fail to work at just 2 years old). I remember the days when your family TV set lasted for 10 or more years. So disappointing Samsung - you have lost your moral compass. And no, I won’t pay to replace the mother board in my set, just to have the new one fail. What a con you have run on people.

I understand your frustration. Can I have your serial number via private message? I would like to look into this more for you.

I have the same problem.  It just started today and my TV was very expensive (60inch ).  Had extended warranty just expired Jan 2019 . I have three Samsungs and from everything I've read on various sites, this is a Samsung known issue/problem and it's common.  What can be done.  I'm frustrated, ticked and more...enough to make me look in to other manufacturers.

We have had nothing but problems with customer service at Samsung!! I can't even call it Customer Service. Our TV was doing this very same thing and then the screen just stopped working on 4-22-19. We STILL HAVE NO TV and Samsung has not honored the warranty by resolving this issue. Nobody replies either. I was on the phone for 4+ hours waiting for anyone to answer and I finally hung up and went to bed. Samsung used to be a good name for quality but after this...I am staying away from all things Samsung (phones, dishwashers, tv's...everything).
