Purple/green rolling horizontal bars and buzzing noise from the TV speakers with a Component cable connection.

Remove the left and right audio connections from the Set-Top box. If the buzzing stops, this indicates that the Set-Top box has a grounding issue. Replace the Component video cables with an HDMI connection.
