so the other day I notice only my right speaker was working. checked the wire to make sure the cats hadn't chewed through it etc. redid the wire and connected it back up. worked fine for a little while. then it dropped again. I check the terminals on both ends and they were as tight as can be. isolated it to the receiver end b/c sometimes just a gentle touch or wiggle on that end will bring the speaker back on. again it's as tight as it can go! the terminal is the twist on kind not the snap kind. the speaker end is also the banana type and they make it easy to insert the wire and twist it around before screwing it down. the receiver end does not make this possible. you are lucky to get them unscrewed enough to get the wire in let alone twist it around the inside posts. so basically you can just get it in and twist the connection on tight. had the receiver for 5 or 6 years and never had this issue till a few days ago.
not sure of the gauge wire but it's pretty thick but not too thick for the terminal. it seems it's coming "loose" just from the vibrations on the hardwood or the little one barely bumping the entertainment center. it may work for hours or it may for five mins. no real rhyme or reason to it.
any thoughts on this? you can't easily replace the terminal can you? is the receiver terminal shot? I'm itching to get a new one with HDMI to cut down on the number of cable runs I have now but the wife would not go for that unless it's absolutely necessary.
