Dead/Muted Notes While Playing

This is a 5.35 minute video response from David MacKenzie on Jun 12th, 2009

Question:

"Landshark asked "I just bought an Ibanez ARX320 from my local guitar shop. It played nice while I was in the store, but after a week, I am getting fret buzz along the entire neck and when I play the 9th fret on the 1st string, the note sounds dead or heavily muted. Also, on the 15th fret of the 1st string, whenever I bend the note, it immediately goes dead. What could be causing these issues? I'm about to return this thing to the store.""
