Screen comes on but won't power up

Question

After shut circuit breaker off to replace an outlet on same circuit. Now Icebox model 85000 will not turn on. The screen energizes but then I don't even get led on front of unit. Who does a person ask for help?? Just let me know what it might be and I'll take the thing apart. I've gotten good 6 years out of the unit but should go for longer than that.
