[QUOTE="Brian Adams, post: 148236, member: 963"] Re: X32 sticky buttons fix I'm not sure if this is what you're thinking, but I'll relay my recent experience. I had a sticky button on one of my X32's, so I decided to go in myself and see what I could do. I'm not sure I'd recommend that anyone do that, but here's what I found: In my case, the sticky button was caused by the switch itself, under the button (each button has a switch mounted to the board underneath it). Once I had the case open and the board removed, I tried other switches which pressed smoothly but the problem switch was always rough, even without the button attached. Since it wasn't the button causing the problem, I figured that the plastic housing of the switch was catching on the plunger and causing the issue, and it turned out I was right. I took the mixer apart, obviously, which wasn't terribly difficult. Then I removed the board with the offending switch on it. Without unsoldering the switch from the board, I disassembled the switch. It wasn't easy, as the little tabs that hold the top of the switch are very difficult to get to while the switch is still attached to the board. By far the biggest trouble I had were the super tiny copper contacts inside the switch, which fell out when I removed the top of the switch housing.
