I found a Pro-Form Trainer treadmill at one of the Amish Wal-Marts around here. It was still in the box, and I got a deal on it.
I've used it for maybe 100 miles. Last night I went to use it, but the buttons don't work. It powers on, and everything looks okay. The incline and speed buttons beep when you press them, but nothing happens. None of the buttons on the screen work, but the display scrolls normally. Any idea what the hell is going on with this thing? I've checked every connection I can get to without taking it completely apart.
