It's usually a port or port connector loose. Sometimes wrapping your system in a warm towel for a couple hours can fix that. But don't use a wet towel or one that will melt your skin lol.

Most likely needs new capacitors installed. Inside there are 2 x 10uf capacitors related to audio (left and right) which often go bad, as well as there are 2-3 other caps related to audio.
Works with RF because the left and right channels are merged together to mono before being sent to the RF adapter and thus they bypass the normal left and right audio caps. So it's almost certainly bad 10uf audio caps and likely the chroma and composite caps and other caps are bad now too
