Possibly the causes are: 1. defective channel B power amp board. But try operating first with the built in tuner, if it's ok the RCA cable from your other sources(DVD player, etc...) might have broken internal conductor.
2. if it has the speaker switch(A, B, A+B) try toggling it, might also just loose contacts.
if the trouble is #1, leave everything to your trusted qualified technician, he knows what to do, unless you want to tweak/repair it by yourself...hope this helps ;-)
