Why is my Samsung 4 4000 showing purple/green bars with buzzing noise?

If you see purple or green rolling horizontal bars and hear a buzzing noise from your Samsung TV speakers when using a Component cable connection, remove the left and right audio connections from the set-top-box. If the buzzing stops, this indicates the set-top-box has a grounding issue. Alternatively, replace the Component video cables with an HDMI connection.
