hi, the right channel on my pioneer sx535 has started to make a static noise from the right channel, it varys between a static hiss to a very loud crackling that has blown a speaker, cleaned all switches, checked all connections and looked for dry solder joints but the problem is still there. anyone had any experience with this problem, any thoughts, hints, tips or guidance would very much appreciated. thanks, mike. please note it wouldnt allow me to post in the technical forum.
