Fix 1: Restart the Seiki TV

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

Turn the TV off by pressing the Power button on the TV itself or on the remote.
Then unplug the cable from the power outlet.
Wait for 30 seconds.
Plug it back then.
Turn the TV back ON using the Power button.

Fix 2: Disconnect the external devices connected to Seiki TV

When there are no external devices connected to the TV, set the Sources to TV.

Press the SOURCE button on the front right side panel of the TV or the SOURCE button on the remote control to display the Input Source list.
Select the Source to the one which represents TV.
Press the OK button to confirm your selection.

Fix 3: Check the power supply to Seiki 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.

You can also try connecting your Seiki TV to a different power outlet and check whether the random turn-off issue is now resolved.

Fix 4: Check the TV Remote

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

Check to make sure nothing is obstructing the TV vents, as this could limit airflow and cause overheating.
