If your Smart TV is not turning on, here is a list of things that you can try:

1. Make sure that your TV is plugged into a working outlet, and that all cords and wires are securely connected.
2. Check your remote and make sure that the batteries are still working.
3. Look for any LED lights or power indicators that may give you clues as to why your TV is not turning on.
4. If you have a surge protector, remove and then reconnect your device to reset the power connection.
5. Unplug your TV from the power source from 30 seconds to one minute and then plug it back in.
