GE Profile-no lights at all on control panel

The lights on the front control panel are not lit, nor do any of them function. It used to work intermittedly, now it doesn’t work at all. I bought a new panel (part #93), but did not work. I tested the wires and am getting power. I also took both my old and new control panel to a friend’s who has the same model, and both of my panels work on his refrigerator. What do I try next? I have see a few posts with the same problem, and even one where the main control panel was replaced, but still did not work.

Please, looking for some help.
