I generated enough static electricity to blow out my circuit board on my treadmill. they don't make the brand anymore and I'm sure it's a blown capacitor or diode but I have no way to check it. There are a bunch big commercial places that build boards but they don't do retail work. If anyone out there thinks that they can check/fix it, I'll mail it to you and pay for the repair. It's a small board wit two to three caps and four or five i/o on it. it's a little bigger than a dollar bill in size.
