I bought YAMAHA RX-V1 receiver a few months ago and love it. I recently realized that my left main speaker was producing very low output as compared to the right main speaker. I switched the speakers to make sure that the speakers were not messed up and now my left speaker is working fine but the right one produces very low output. What I mean by low output is that the speaker generates sound but its very low as compared to the other speaker. The authorized repair store is abut 1 hr away from my house. Is there any fix to this problem????
