Fix 1: Restart the Samsung TV

Most of the issues with Samsung TVs can be fixed by restarting the TV. So, as a first step, just restart the TV.

Then unplug the cable from the power outlet.

Fix 3: Check the power supply to Samsung TV

Check whether your power cord is broken or damaged. If it is broken, then you need to replace it.

If it is working fine, then you need to check the power outlet. If there is low power, then your TV will keep turning off.

To check the power outlet, you can connect some other device to the same power outlet and check whether it is working fine.

Fix 4: Check the TV Remote

Sometimes, the TV remote will send signals to automatically turn ON and OFF your TV at random intervals.

It’s usually because your remote batteries are low. Remotes are known to send off some weird signals when they’re on the last bit of juice.
