Y sus board buzzing

Try another input and another source such as a DVD player. If you still get the buzzing sound, you could have a faulty power supply output or a fault in the audio circuit of the main board.

In almost all cases this is caused by a small transformer which is vibrating hard enough to cause the buzz.

The louder it is the easier to locate it.

Repair techniques vary from locating and dampening the sound with Hot Glue Gun to just replacing the entire board that it is on.

It is irritating but poses usually no safety issue.

Hint: usually in newer sets it comes from the power supply board.

Ur tv have a colors wheel design in it.Tv have buzzing,squiling or loud motor noises.Have colors turn in Black&White or flashes white within pictures.All these causes and problems are the effect of the colors wheel is dying and require repacement of the colors wheel,because it is woring out and not spinning correctly on it motor axis anymore.Have no machanical experience taking things aparts and putting it back together again.Don't atempt to change the colors wheel by ur self,bacuse the colors wheel sit way back on the tv,must take out many machanicals parts before u can even come to it to change it.Hire a Tv Tech. to change the colors wheel ok best solutions and no complication taking out the old one and putting in the new colors wheel,for it to functions correctly.

U have tools like a soldering iron,a roll solders,also can u do basic soldering?Yes.This tv have cold solders joints in the(CRT-Tv tube) video board connections pins socket that connected to the(CRT-Tv tube).The tv loud buzzing sound is comming from the FBT-the flyback transformer,that is a big black block of plastic with a red wire with a cap that hook to the(CRT-Tv tube).Resolders both the FBT and the video board CRT socket holes connections.Will solved these 2 problems.

I have this tv aswell, and yes I will confirm that it does buzz quite alot, but all plasma tvs do, it is to do with how it renders images, the buzzing can be made worse by it being close to a wall and it reflecting back. I found that my tv stand some how amplified the buzzing when i got mine. I dont think its something you can escape.

Mine i notice also when scrolling around menus seems to have lines that follow your selection....not to pleased about that

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.

No,fan in Plama tvs,fan only in DLP tvs.One of the power transformer in the power supply board is not give out the right high voltages.

A buzz in the sound usually indicates poor grounding somewhere or bad filter caps in the power supply. Lines moving up the screen used to be common in old tube sets, also indicates bad power. Have you opened up the back for a look?

You need to adjust the voltage on the Power Board, but small possibility.

I think that need to replace with new Power Board.

Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?
