It sounds like you want to get the audio from your TV to your Sony shelf stereo. Is this correct?
Could you provide some model numbers for your equipment so we know what you're dealing with?
Just a wild stab here but it sounds like your stereo only has a 3.5mm or headphone input. If that's the case, then check to see if your TV has a headphone output.
Again, model numbers and clearly defining what you're trying to do makes this a lot easier.
