Plug - If the TV is not powering on and no status LEDs are lighting up, start by plugging the TV into a different outlet. If the TV is too challenging to move, you can run an extension cord from another nearby outlet.
Circuit breaker - Check the circuit breaker for the power outlet that the TV plugs into. You can check the breakers by opening the door to your breaker panel and looking for circuit breakers that are in the OFF position.
Power cable - Check the power cable. If it is a removable cable, you can test it by substituting a power cable from another piece of equipment in your home, or you can buy a replacement cable for this test.
Remote control - If the TV is not powering on with the remote control, you should try replacing the batteries. For remote controls with a status LED light, there could be enough power to light the LED but not enough power to send a signal to your TV.
Auto power off – One can rectify this issue by following the below options:
Check if any timer or sleep mode has been set by mistake
Check your remote control
Remove the main power cable
Unplug all devices attached to the TV such as cable connection, media player, speakers
After 1 minute, connect the TV
