Thanks for the suggestions. I'm planning on opening it up soon and taking a look. Maybe the degauss cable is loose or disconnected from the analog board? I'll also look at those components, but I'm not sure I'm willing to or capable of using magnets around a CC. I may never have another one, so I don't want to risk it. Same goes for de-soldering components unless I can be reasonably sure they've failed.

Anyway, I'll report back once I find time to get it open.
