Jenn-air oven(s) displays burnt out

Boy, this Jenn-air stuff is junk. I’ve got 2 ovens with burnt out displays and a microwave with display problems (I posted to microwave board on that one).

The second oven model is svd48600w. The displays on both of these ovens are totally dark. The keypads still work including the beeps on input. Both ovens work. I’m thinking it’s the oven control on the backside of the keyboard membrain. It has the floresent display attached to it. I just want to be sure.

By the way, all 3 units burnt out at way separate time frames, so it was not a surge or lightning.

Thanks.
