I am having troubles with playback on a TV with the A/V connection on my Sony PMW-200. I record and monitor 2 channels of audio absolutely fine but when it comes to playing it back with the A/v cable it only plays back the audio from Channel 1. I have tried changing all the audio output settings in both playback and record more but still no luck. I've also tried swapping the A/V cable for a new one and still have the same problem. Is it possible that the A/V socket could be damaged.
