Follow the below instructions to resolve your TV issues.

Samsung TV automatically switches to standby mode when there is no signal. It saves power by turning the TV off automatically when no signal is received from the current source.

If your TV appears to turn off by itself, try disabling some of the TV's energy efficiency functions.

Turn off the Auto Power Off: Navigate to Settings > All Settings > General & Privacy > Power and Energy Saving. Then, turn off Auto Power Off.
