Common Culprits, Why Samsung TV Keeps Turning Off and On

  1. Power and Energy Saving Features: Eco-conscious features like Eco Solution and Auto Power Off can sometimes take their green zeal a bit too far. Check your TV settings and ensure these features are disabled or adjusted to suit your viewing habits.
  2. Sleep Timer: This handy feature lulls your TV to sleep after a set period, but a misconfigured timer could be the culprit behind early snoozes. Double-check the sleep timer settings and tweak them as needed.
  3. Software Issues: Outdated software can sometimes lead to unexpected glitches and shutdowns. Keep your TV updated with the latest software for optimal performance and bug fixes.

How I Fixed Samsung Tv Keeps Turning Off And On

After years of fixing countless Samsung sets, I’ve learned a few tricks for troubleshooting models that get stuck cycling on and off. Let me share what tends to work in my repair center when we see this issue:

  • First, attempt a simple soft reset – with the TV powered on, hold down the button on the TV itself (not the remote) for 10-20 seconds and let the set reboot fresh. Clearing temporary memory glitches works surprisingly often.
  • Next, unplug all HDMI input cables from the malfunctioning TV, unplug power too for 5 full minutes, then reconnect everything. That “unplug it and plug it back in” step resolves flaky signal issues more than you’d expect!
  • While you have access to the ports, take a moment and make absolutely sure your TV firmware is fully updated. Failing updates can corrupt background processes and cause all kinds of quirky behaviors.
  • It’s also worth examining your Samsung remote, even trying new batteries or setting the remote aside altogether momentarily. Interference or unexpected signals from the clicker can confuse a TV’s logic board.
  • If issues continue, the root cause may be hardware deterioration on the internal main board or power supply board. In the shop, we open up and check for any burnt connectors, damaged capacitors etc. If replacement parts cost exceeds the TV’s value though, it’s not worth additional repairs.
  • In that event, I’d recommend considering a brand new Samsung set altogether. Eventually the older models just wear out electronically. Preventative maintenance helps, but parts fail over 5+ years of use typically.

Hardware and Connection Issues on Samsung TV

  • Loose Connections: Wobbly power cables or poorly connected external devices can disrupt power flow and trigger shutdowns. Give all connections a firm wiggle and ensure everything is securely plugged in.
  • Power Supply Problems: Faulty outlets or surge protectors can also be the gremlins behind your TV’s woes. Try plugging your TV into a different outlet or surge protector to rule out this possibility.
  • Remote Control Issues: Sticky buttons or low batteries on your remote can send unintended power-off signals. Check the remote for any malfunctions and replace the batteries if needed.

Advanced Troubleshooting

Factory Reset: For persistent issues, a factory reset might be the cure. Remember, this resets all settings and erases data, so proceed with caution.

Contacting Samsung Support: If none of the above solutions work, don’t hesitate to reach out to Samsung Support. Their knowledgeable team can provide further guidance and assistance.

  • Checking if the remote control’s power button is stuck.
  • Trying a soft reset by pressing and holding the power button on the remote for 30 seconds.
  • Unplugging the TV overnight.
  • Giving the TV a good smack on the back (Fonzied it), which seemed to work temporarily for the OP and some others. NOT RECOMMENDED.
  • Checking the batteries in the remote, as weak batteries might cause issues.
  • Exploring potential interference from other remotes.
  • Considering issues with the TV’s main board, panel, or power supply unit.

It’s important to note that smacking the TV might not be a recommended solution, and it could potentially lead to further damage. The community members shared their own experiences, and it’s unclear if the suggested fixes worked for everyone. If you’re facing a similar issue, it’s advisable to consult with a professional TV repair service or contact Samsung support for assistance.


With a little detective work and the tips in this guide, you’ll be well on your way to diagnosing and resolving those pesky TV shutdowns. Remember, start with the simple solutions first and work your way up if needed. Most importantly, keep calm and enjoy the journey back to uninterrupted viewing bliss!
