I picked up this 2.1 Edifier M3300 Speaker set at the Goodwill cheap. The Right RCA connection doesn't produce any sound except for a buzz. The left connection is fine. I check the speakers and they both work when plugged into the Left connection.
How do I figure out how what is wrong? Could the amp be broken or just the connector?
I don't mind just 1 channel, but if I could fix it, I would like to try. If it's too complicated, I'll just leave it alone.
