Audio Systems: Right stereo sound not working, amplifier output, bench test

Question
OK, on my stereo the right outlet sound wont work but all my speakers work fine. Whats the problem and can I fix it? Please help

Answer
Dear Lucas,

When a channel fails, there can be many causes: the power amplifier output, the preamplifier signal chain, and so on. The only way to determine the real cause and appropriate remedy is to take the unit to a qualified repair service for a diagnostic bench test.

Kindest regards,

Kevin
