GE side by side

The freezer is working but the fridge isn't cooling and the display is no longer lit unless I push a button then they work for a bit then go out again.

This started after I broke the light switch and all four bulbs remained on for a day. They got very hot, as did the back of the unit. Now the fridge won't stay cool and the display lights keep going out. Since then I cleaned a bunch of dust out of the rear and have unplugged it for 10 mins. But it still doesn't cool. The master circuit board doesn't have any visible damage. Can you help?
