Blaupunkt Arizona

[gejettest]

Hello, I have a older Blaupunkt Arizona head unit and has volume issues.  All by itself left side channel goes silent.  Also, if I adjust the volume dial it doesn't respond very well, it will start to run away in the increasing direction, I have to hit the mute button to get it to stop.

I bought another new faceplate thinking that might be the problem, no effect.  Still does these annoying things.

Anything I can do myself?  Unit not worth taking in and paying more than what it is worth.  I'm an aircraft mechanic, so I can use a multi-meter and have good mechanical skills.

Thanks in advance,
