Mcintosh Volume control acting erratic

It could be a static discharge when you touch the unit. That is what happened to mine. Simply turn it off and unplug for a few minutes and you should be good to go like Theo says.

I have had a similar problem for some time to the point where the only way to change volume is via the remote. I spoke to the folks at Mcintosh who told me if the reset doesn't solve the problem, it will need to be sent for service. I would be less bothered by this if the remote weren't so cluttered. Anybody know of a quality programmable remote-somthing like Simaudio's-to provide very basic functions. Volume control is all I need

Depending on how many compnents you want to program into a remote I have the marantz RC1400 and love it. I had the RC2000mkII and that was good but not enough memory. But I run my whole system 9 componnents with this little remote and a couple of macros. I like the ability to punch through other component functions to each component screen.

As an Authorized McIntosh repair center, we have had more than 2 Optical Encoders fail (one in an MX-132 and another in a C2200 I seem to recall) and they reflect your exact symptoms when failing. Take her in for service and McIntosh will take care of you.

My problems is not only does it get stuck, but it changes on it's own. I have a computer modem within 3 feet and am wondering if that could cause it.
