I recently got a vs-502 a/v switch. I have 3 sources hooked up to it via component, s-video, and composite. It upconverts all 3 signals to the component out and is set to automatically select the proper input. Sometimes when I turn off a source (ie. DVD) it goes back to the previous source (like it should), but then resets itself (turns off, then back on without remembering settings). Any ideas on what might be causing this? Could the unit be bad? Thanks for any input.
