What it means
In normal use the red standby light is on when the TV is off and goes off when the TV is in use. If it blinks and the TV will not start, Samsung asks you to rule out power: 30 seconds unplugged and a working outlet, with no surge protector, since they may wear out and stop providing the necessary voltage. If the light turns steady, the original outlet or surge protector was the issue. If it keeps blinking, Samsung says something is wrong with the TV; it does not name a part.
