Samsung TV Turning On and Off – Fixes

As mentioned earlier, this issue is frustrating, and this is where you start to question whether your TV is smart or not. However, there’s no need to worry. There are several troubleshooting methods available to address this problem. You can try all the methods mentioned which will definitely fix the issue of your Samsung TV turning on and off frequently.

Fix #1: Power Cycle the TV

The first thing to try to solve this issue is to leave your TV unplugged for sometime. In this method, all you have to do is disconnect any devices from the TV as well as remove the TV plug from the power outlet. Leave the TV unplugged for 60 seconds. After removing the power source, press and hold the power button of your Samsung TV for 30 seconds.

This performs a soft reset where anything present in your TV’s RAM will be cleared off. After the 60-second period passes, plug your TV back into the power outlet and switch it on. Now observe and see if your Samsung TV turns itself on and off. If not, well and good, or else, you still have other troubleshooting methods to try.

Fix #2: Check for Cable Damages and Loose Cables

The power cable is an important cable for your TV, as it’s used to power it up. If there are any damages or cuts on the cable, it is advisable to get this cable replaced right away. Using your TV with a damaged cable can harm the TV. So get it replaced, and your TV should not be tuning itself off and on repeatedly with new cable if it was the real problem.

Also, if the cable is loose and causing it to disconnect from the power source, then this could be the problem, so be sure to fix it.

Fix #3: Check HDMI Connection and Cable

HDMI allows us to connect different devices with TV. And if you have connected multiple devices, then you should try this method as well to fix Samsung TV turning On and Off.

  • Remove all the connected devices and connect them back.

  • Only use good quality HDMI cables.

Fix #4: Inspect the TV Remote

The remote is an important device that you use to control your TV and perform basic functions right away. With that being said, a damaged remote could be causing your TV to turn itself on or off. Especially, if the power button on the remote is stuck into the remote.

To solve this issue, you can simply use a pin to slowly free the button. Or the best you can do is remove the batteries from the faulty remote and get yourself a replacement remote. This should solve the issue of your Samsung TV turning on and off repeatedly.

  1. Thank you Thank you Thank you!!! Thought I would have to buy another TV until I found this site. Fix #1 did the trick. You guys are genius.

  2. None of these worked for me but disconnecting wifi and then powering on the TV allowed the software update or whatever was causing the issue to fix. Posting here in case it helps.

  3. Took Alan’s advise and turned the wifi off. After which I used a wired connection and interestingly the same issue took place. It became clear the issue is with the network connections.

    Isolated the problem by using Google Chromecast and the TV seems to be working fine.
