and action movies.

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.

try rerouting your connection cables.
• An improperly installed of wall mount can also create excessive noise.
