I have a troublesome Pioneer VSX-14 that has been acting up a bit lately. It has just occurred to me (at work) that MAYBE I have a short at one of the speaker connections. The receiver shuts down intermittantly with no apparent cause and will turn on if I move the unit around. Sitting here using the search function..I came across a possible cause..speaker wires may be loose in a banana plug and shorting out to another plug or binding post. what are the signs of speaker wire shorting and what would a receiver do when this happens?
