I recently purchased a rs-800 combo vending machine that worked perfectly when purchased used. The guy I bought it from showed me how to test each bin and use the service screen. There was no issues until it came home and I tried to test the bins again and play with the features, however, when I pushed the yellow button the screen stays frozen on whatever it was on, this mostly being “sales”. I cannot push any other buttons with it having an affect. It just stays frozen. Any help?
Had a similar problem with a different brand combo vending machine, it turned out to be button sticking on the keypad. I had to order a new keypad for my machine.
