Hello, I have an older GE Profile Arctica SxS that is having a display problem, as in there is nothing showing up on any displays on the inside control panel or the ice dispenser panel. The refrigerator and freezer are still both cold. I just cannot see any numbers on the displays, change temps, or get water/ice dispenser to work.

I did replace the control board in the back of the unit with one from my garage unit (same model) and it worked for a day and then stopped again.

Suggestions?
