I have a 27" magnavox that is only a year old and when I got it to my dorm the audio kind of skips, sort of like what it sounds like when you start to get out of range of a radio station. I checked my cables and they are undamaged and fastened securely. Could a speaker wire have gotten rattled loose inside the tv? Is there a way to find this out without taking it to get it repaired?
