Hey guys, one of my neighbors put one of these out in his driveway with a note indicating the control board was bad. I picked it up and started tinkering with it, and the control board beeps when you plug it in but doesn't respond to pressing any of the buttons and the display doesn't work at all. I removed the control board and its in really great shape with no signs of anything wrong with it. The capacitors don't look puffed up either. Any ideas on how I can diagnose exactly what's wrong? Thanks everyone!
