QLED and The Frame

My QLED is just over 2 years old and it is power cycling. I have tried unplugging it and plugged it directly into wall socket but it still power cycles. It is not on long enough to enter the menu. Needless to say I am extremely disappointed with a  $1,000 TV 2 years old failing. What else can I do to get it working?

I understand how this can be frustrating with your TV power cycling like this have you tried the troubleshooting steps below? 


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.

  1. Unplug the TV for 30 seconds.

    Unplug the TV from the wall outlet or surge protector and leave it unplugged for 30 seconds.

  2. Inspect the power cord for damage.

    Check the power cord to see if there is any visible damage. If the power cord appears to be damaged. You can get a replacement at samsungparts.com.

    You can search for your TV model to find the exact power cord you need.

  3. Plug the TV power cord back into the wall outlet.

    If you were using a surge protector, bypass it for now and use a wall outlet.

  4. 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.

  5. Disable the Power On with Mobile option.

    TVs which 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 troubleshooting steps did not help above then this will require service, you have a couple of options based on your warranty. 

- 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 set up. 
- If you're within the one year warranty, you can Private message me or one of our moderators with your full model and serial number to have service setup
- If you're OUT of warranty, you can use this link below to find a service center in your area.

QLED and The Frame

You did not read my  description of my problem. I have already done all of these items and I do not have any devices connected to my tv. After searching the internet I can see that I am not the only one that has had this issue. It seems to be a wide spread problem with Samsung TV's. 

My 55” QLED TV started power cycling. Can’t even keep my TV plugged in because it will continue to cycle on/off every 10 seconds. The ‘Samsung QLED’ screen comes up but the home screen never appears. The TV turns back off and cycles again before this is possible. I am now countless hours into researching this and I see on the Samsung forum that this is a HUGE issue (and also a known one..). My TV is  two years old. Looked up BB charge this morning and confirmed I purchased Mar 2019.. truly disappointed..

I have tried - unplugging-from both wall and tv, unplugging all external hdmi connections, disconnecting router to force-stop firmware update, and have tried the random suggestions as well, such as holding the power button on the tv, replacing batteries in remote, etc. I have seen a few suggestions around updating firmware with a flash drive but don’t have confidence in my skill set to do this properly. And suggestions from other Samsung customers?

Is my 2-year old tv really doing this..?? I am speechless.. I can’t believe I’m not even able to keep my tv plugged in… Based on the 100+ comments around this challenge, sounds like Samsung should stand by their product and take care of this for me. And Samsung, please don’t send me the standard troubleshooting message. I am way past level 1 support. 

I just recently purchased another Samsung QLED and had to exchange it as the first one I received did not function properly. If I had this problem with my existing TV I would not have purchased another Samsung.  Thanks
