You could test at the main control board to see if there is voltage from the main control board to the display board.

When the red light goes out on the main board I loose power out

This does sound like it would be a faulty control board.

I am leery of buying a new board since I don’t know what caused the original one to literally burn up. My wife heard a loud pop, and it started smoking. It wasn’t running at the time.

Should the red light on the circuit board stay on with only the two power plug-ins coming from the the voltage filter thing plugged into it all other plug-ins unplugged
