Whirlpool Range: Dim Display

The display on my Whirlpool range in dim. The green LED clock numbers are fine. It’s the red LED temperature display numbers that are very dim and can’t not be read. I’m sure the problem is in the control/display board. My question is what is going bad on these boards? Capacitors? Resistors? I have talked with other people that have the same model and they all say that their display are or is going dim. Does someone know the repair that can be done on the board? (Board level repair!!!)
Thanks Ken
