Yamaha CR-420 problem. Help!

[rromeo]

I was listening to my Yamaha Cr-420 and noticed that my B speakers were not working. Then the left channel started to go in and out of my A speakers. Then it was gone altogether. The headphones have both channels.

Any ideas?

I would start with standard cleaning procedures using Deoxit. In your case it may be dirty speaker selector switch.

Fixed!
Deoxit is your friend!
Deoxit on the A/B speaker switches fixed the B speakers. Deoxit on the Speaker red/black post fixed the left A speaker.
It was just weird that it happened all at once.
