Connect the TV to a different wall outlet. If the TV is connected via a power strip/surge protector, then try connecting it directly to a wall outlet. If the issue is resolved, then the problem is with the power strip/surge protector and not the TV.
Follow the steps below to resolve this issue:
Turn off the TV.
Unplug the TV power cord from the electrical outlet.
Let the TV remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Locate the nearest authorized service centers from the below link.
