Plug the TV in. Do not press power yet. Look for the standby LED. Press power. The screen should glow within 3 seconds.
A: If the TV is over 6 years old and the screen is 40 inches or less, probably not. If the TV is a 4K 65-inch model (2-5 years old), definitely yes. A $40 BP board is far cheaper than a $600 new TV.
