Samsung fridge no water or ice dispensing

Got a Samsung everything works except the dispenser. No water or ice dispensing. I makes ice but when you push the leaver nothing happens. I was going in and out for about 6 months or so and finally quit all together. I replaced the ice maker and the main control board. I’m thinking its in the display board, but I don’t know how to get the display apart. Theirs one screw and I tried to slide it out and its stuck, so I don’t want to break it. Can someone show to tell me how to get the display off?
