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.

Plasma TV is 
making humming 
noise.   for PDP TV  
•Plasma TVs typically make a soft humming sound. This is normal. It’s caused 
by the electrical charges that are used to create the images on the screen.

too high. Try setting the brightness lower.
 
•You can also have loud humming if the back of your Plasma TV is too close\
 
to a wall or other hard surface. Also, try rerouting your connection cables.
