A buzzing sound in a plasma could be becuase you live at a higher altitude. This is an issue with plasmas only.

We usually find this is the cabinet back rattling. To confirm, when this happens turn the volume on the set all the way down and see if the problem is still there. If it is still there the put your hand on the back of the tv and gently press to see if the buzzing goes away. If the sound does go away the cure is to loosen all of the back cabinet screws around the edges of the set and gently push on the back as you tighten the screw. tighten the screw in an order much like you would tighten the lug nuts on a tire. in other words thighten the top left screw, then the bottom right screw and kepp alternating as yougo around the dabinet back untill they are all tight.

I have a 42 inch Hitachi plasma tv that is making a very loud static noice coming from the internal speakers. It stays at a contstant very loud volume unless I completly mute the tv or turn the volum


Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

Humming sound


Samsung states - A buzzing sound from your plasma TV is normal. It is caused by the electrical charges 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.It is also important to determine the type of buzzing sound. A sound like a ground hum is completely normal. This buzzing can originate near the power cord connection or from the SMPS board position on the upper back of the TV. The buzz will be more audible as contrast increases on the screen, most notably when displaying an all white screen. If the buzzing sound is loud, you may have the Contrast set too high. Lower the contrast to reduce or eliminate the buzzing.You may also have loud buzzing if the rear of your Plasma TV is too close to a wall or other hard surface. Try moving your TV away from the wall until the buzzing is minimized. [1]
If the buzzing is at a higher frequency and resembles a crackling sound (like the sound of Velcro being pulled apart), and originates from the upper middle back of the TV, you likely have a failing SMPS board. Place a support call with Samsung to have the SMPS board replaced.FP-T5084 Have a known buzzing problem with a very simple fix.If the buzzing is coming from the left or right sides of the rear and the volume can be changed by pressing lightly on those locations, you are probably hearing the vibration of the grounding springs on the back panel. Call Samsung (or whoever) and have a technician confirm the problem. The easiest fix is to insulate the offending spring by applying some felt tape.

Ive just purchased a samsung 50 inch plasma which makes a buzzing noise like a fridge. i already had a phillips 42 inch and this made hardly any noise. is this normal as its driving us mad.


This unit should not make a noticable buzz. Bring it back for an exchange. There is a problem with the switch mode power supply.

You have a cracked panel and the gasses inside have escaped. The buzzing noize you are hearing the the current flowing throught the panel. It will be cheaper buying a new TV than buying a replacement panel. But if u wanna check out the price look up your model on parts.com

Buzzing


The noise is caused by dust on one of the toroidal transformers(usually a round looking thing with wire wound around it). Go to the back of your television and try and pinpoint were the sound is coming from. Turn your television off and blow it out with compressed air if it is close to air vents in the television. If you cant see it you might have to open your television back panel.
