Oven display stuck on PF- will not respond to keypad

My oven is a gas range. The top burners turn on no problem with the knobs. The control panel however is completely non repsonsive. The clock works, and it shows a time along with PF. I have shut it off, left it, but turning it on simply leaves a PF. The control pad does not register me pressing any/all buttons. I have seen numerous responses- including ferrite beads and replacing the whole panel…suggestions please?
