6 Fixes for Samsung TV Turning On and Off Itself Repeatedly

ByJim Miller

Is your Samsung TV randomly turning on and off itself? Don't worry; it's not haunted. This issue is usually caused by a software bug or hardware failure. Fortunately, there are several solutions you can try to fix the problem and prevent your Samsung TV from turning on and off automatically.

1. Basic Solutions

Before diving into advanced troubleshooting, it's always a good idea to check the basics first. Here are some basic solutions you can try:

  • Unplug the TV Power Cord: Sometimes, simply unplugging the power cord for a few minutes can resolve the issue. This allows the TV to reset and clear any temporary glitches.
  • Inspect the Power Cord for Damage: Check the power cord for any cuts or burn marks. If you find any damage, you may need to purchase a new power cord.
  • Check the Wall Outlet: Ensure that the power cord is securely connected to the wall outlet. If the outlet has a loose connection or is damaged, try switching to another outlet or use an extension board to test it.
  • Check HDMI Connection: If you're using uncertified or low-quality HDMI cables, setup boxes, or gaming consoles, they can cause the TV to behave abnormally. Try disconnecting the HDMI cable to see if this resolves the issue.

2. Disable Auto Power Off

Samsung Smart TVs have a feature called Auto Power Off, which automatically turns off the TV if it detects no user movements. However, this feature may mistakenly turn off the TV while you're still using it. To disable Auto Power Off, follow these steps:

  1. Go to All Settings.
  2. Navigate to the General & Privacy section and select Power and Energy Saving.
  3. Make sure that the Auto Power Saving mode is disabled.
  4. If the Auto Power Off mode is enabled, select the Off option.

3. Update Your Samsung TV

Software bugs and glitches can also cause the TV to turn on and off repeatedly. To check for software updates on your Samsung TV, follow these steps:

  1. Navigate to All Settings > Support > Software Update.
  2. Select the Update Now option to check for updates.

Samsung is known for quickly delivering fixes for any known software issues, so updating your TV may resolve the problem.

4. Disable SmartThings

If someone has connected to your Samsung TV using the SmartThings app, they can remotely turn it on and off. To restrict this feature, follow these steps:

  1. Open the Settings on your TV.
  2. Go to Connection > Network.
  3. Navigate to Expert Settings.
  4. Click on the Power On with Mobile option to disable it.

5. Factory Reset Your Samsung TV

If none of the above methods have fixed the issue, you can try resetting your Samsung TV. This will erase all your account information and any incorrectly configured settings, which may resolve the problem. Here's how to do it:

  1. Go to All Settings.
  2. Navigate to the General & Privacy section and select Reset.
  3. Enter the PIN (the default PIN is 0000).
  4. Hit the Reset button to initiate the resetting process.

Once your TV turns on, check if this fixes the issue of it turning on and off.

6. Contact Samsung Support

If you've tried all the above solutions and the issue persists, it's time to contact Samsung support. They will be able to provide further assistance and guide you on the next steps, including visiting a Samsung authorized store for repairs.
