Fridge not working, No cooling, and no display

Our second fridge stopped working. There are no lights on the front of the fridge where you adjust temp and dispense water. The inside lights are working and I can’t hear any fans or anything running.

Looks like it was make around 2006.

Is it worth fixing? I suspect the control board in the back but before I spend almost $500 for the board, I’d like to know that’s the problem.

Thanks,
