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.

DLP tv will turn on (picture looks fine) then after a minute TV will turn off. Sounds like its trying to come back on for a couple of seconds, then I start to hear a buzzing sound for a minute, then it...

Hi Karen,

It sounds like the color wheel of your unit gone to malfunction and trigger that kind of symptoms. It needs to check by a qualified TV Technician because this kind of symptoms is not a DIY unless you have an experienced in electronics. If the buzzing sound came in front of the lamp assembly, then high chance that the color wheel is already faulty. Lamp, ballast board, fans are also a suspect here.

Have a nice day!

Have just bought an LG37LD450. Buzzing noise coming from the components at the back of the TV. Annoying. Otherwise TV perfect. Definitely not sound problems because buzzing noise still there when on Mute....

Had this problem as well. Ran through a laundry list of possible solutions. Finally found that the key is to increase the backlight (Access via [Menu] [Picture] ) to 100% and the noise goes away. If this is bad for the life of the backlight, just pray the backlight burns out inside year 1 while the warranty is still valid!

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

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.

Hello, normally this buzzing sound comes from the power supply, before you go out and replace the power supply for this noise try to lower the backlight, this might make a difference in the noise but also be very aware that your TV might be a little darker than before.

Plazma TV buzzing noise

I have the same problem I can hear buzzing over the volume of the tv into the 30 range. I've had a tech out 3 times and he's coming out for a fourth. He's changed to power supplies and is bringing the 3rd next visit. From what I've read it has either to do with power supplies or grounding strips.

Buzzing noise, sound but no picture

It sounds as if the lamp needs to be replaced. The buzzing sound you hear is the ballast attemting to fire the lamp.

Verticle lines on screen

This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
