Yes, I did! The headphone jack was malfunctioning, apparently from plugging the headphones in and out too vigorously. The guy at the repair shop attached it more firmly and suggested that I be more gentle when plugging in and unplugging the headphones. Not sure where you're located; I'm in Boston, and the people at the Musical Instrument Service Center (http://miscfix.com) near Berklee College of Music were great to work with. Very helpful. It was an inexpensive repair. I have had no issues since, and it's been two years. Good luck!
