Believe it or not,I took the thing apart yesterday(I figured it couldn't get any "more broke")spent about three hours "looking" at it ,put it back together,made a few adjustments and the thing started working again!I had a shop teacher in high school tell me that sometimes electronics and mechanical things just get lonely and just need someone to look at them to start working again.I've never been afraid to take something apart and try to fix it since that day!More often than not, it's something obvious that's wrong and you can figure out how to deal with it.
