Solutions and Explanations
•
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.
•
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.
•
If the humming sound is loud, you may have set the brightness on the TV
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.
•
An improperly installed wall mount can also create excessive noise.
