How do I deguassa VS-55601

Many manufacturers put a software degause feature in the main menu. There should be an option for deguassing, I am not a hundred percent on this model but if you look in your operations manual it will tell you if this option is available. If not you can purchase a deguaser at a local electronics supplier. It is basically a round donut shaped electro magnet use caution and follow the instructions. Remember in the future to always keep external speakers away from your TV sets..
