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.
• Improper installation of wall mount can create excessive noise.
