Re: receiver not coming through tv

If you mean TV audio, and you have digital audio coming from the TV, then your receiver won't be able to process this signal. Your receiver is from the early 90s.

AV receivers are known for having bad solder connections internally, at the RCA jacks and the interconnecting pins between boards.
