Is The Buzzing Sound My Plasma TV Making Normal?

Last Update date : 2012.01.10

The buzzing sound your plasma TV makes is normal. It's caused by the electrical charges that are used to create the images on the screen. The buzzing, however, should not be so loud that you can hear it when the volume on the TV is set at normal levels.

If the buzzing sound is loud, you may have set the brightness on the TV too high. To decrease or eliminate the buzzing, try setting the brightness lower. You can also have loud buzzing if the back of your Plasma TV is too close to a wall or other hard surface. To decrease the buzzing, try moving your TV away from the wall.

Fixing the Problem

There are two ways you may be able to fix the blurriness problem:

·         Using the Sharpness function

·       If you have a cable box, by changing the connections

Both are described below.

Using the Sharpness Function

If the picture on your Plasma TV is blurry, you may be able to clear it up with the Sharpness function. To use the Sharpness function on most Samsung Plasma TVs, follow these steps:

1.       Turn on your TV.

2.       Press the Menu button on your remote. The Main menu appears.

3.       Press the Up or Down arrow button on your remote to select Picture, and then press the Enter button. The Picture menu appears.

4.       Press the Up or Down arrow button on your remote to select Custom, and then press the Enter button. The Custom menu appears.

5.       Use the Up or Down button on your remote to select Sharpness.

Note: On some model Plasma TVs, you use the Enter button to select Sharpness.

6.       Use the Right arrow button on your remote to increase the sharpness.

7.       Press the Exit button to exit. 

If You Have A Cable Box: Changing Connections

If you have a cable box, and standard channels are blurry, chances are you have your TV connected to your cable box using the composite (standard, AV, Cable) or S-video connections. These are the lowest quality connections.

To improve your picture, try connecting your Plasma TV to your cable box using the Component (Pb, Pr, and Y) connections. If you have digital cable or you receive over the air digital programs, try using the digital DVI or HDMI connections. Examples of a DVI connection, an HDMI connection, and the Pb, Pr,and Y Component connections are below:

Component and DVI connections carry video only. If you choose the Component or DVI connections, you must also connect the Left and Right Audio out on your cable box to the appropriate Left and Right audio in jacks on your TV. HDMI carries both video and audio. If you choose HDMI, you need to connect only the HDMI cable.

Note: If your cable box doesn't have Component, DVI, or HDMI connections, contact your cable company to see if they have replacement boxes with these kinds of connections built in.

Important: If you change the connections you use, make sure you use the Source button on your remote to change to the appropriate video source when you watch your TV.
