Whirlpool RBD305PDT14 not working

My whirlpool double oven RBD305PDT14 stopped working. First, all that would display on the screen was the timer, and it was very dim. Then, it went all dark. The oven still cooked for a little while then stopped.

I reset the circuit breaker, and the oven worked for a little while then stopped. Now, there is nothing on the display, but the overn lights still work.

It beeps a few times if the start button is pushed.

From what I’ve readh here, is it the control panel or control board perhaps?

Sorry to bump this post, but my wife is all over me to get the over fixed. Any ideas?

Here are the parts

And a manual

Most likely is the control board since it has the display on it.
And the dimming of the display is usually a fault on the board

I would check that the transformer which feeds power to run the board is OK.
I beleive the output voltage should be 28 volts but am not sure on this.
Perhaps someone who knows for sure will jump in.
