I have a sony home stereo system LBT-A30. It is about 12 years old. The right side speaker isnt working. I checked the speaker it isnt that.So it must be something internal. If I knew what is was I could probaly fix if was a matter of swapping out a part or even a little soldering. Anybody got any ideas?
