Loud humming or buzzing when set is in operation

We noted the the buzzing is located in the area of the lamp. As soon as the lamp ignites, the buzzing begins and continues to get louder as time passes.
We changed out the lamp but the errant sound begins with the lighting of the new lamp. We suspect the motor on the color wheel.

    Same thing happens to me and the picture colors change and distort. Can a color wheel be changed by me or do I have to get a technician?

Does the picture gets distorted in any way when you hear the buzzing noise?
I would suggest to check all the cooling fans for proper operation.

Singer Touch-tronic 2000 makes loud humming/buzzing noise, stitch selector lights quit working, needle bar stopped moving.

Sounds like you've got a thread jam going on in the bobbin case area. Good cleaning and a new needle will probably fix it. See: https://answers.yahoo.com/question/index?qid=20091202121550AAHxN8y

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...

I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

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.

On off switch does not work somtimes set goes on and off comes on with sound but no picture un plug it and sometimes it works fine

i,
Well basically Sam sung most common parts that go out are,
LAMP: The generic lamp will go from 3500 to 4500 hours and a Phillips lamp will go for 6000 to 8000 lamp hours,
How It Works The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp. The lamp works with the ballast to project light into a light engine that separates the colors of the light, then recombines them with an image. The image is then reflected on the back of the TV and then onto the screen. But you need to listen carefully for any strange noise like (CLIKING,HUMMING,BUZZING,WHIRLING SOUNDS) that will help you narrow down whats is wrong with your TV because the BALLAST witch is the board in charge of sending the correct amount of current to your lamp could be weak and will not power up you will hear a clicking or electrical humming Also the color wheel is a common part that goes out on Samsung and that will give you a vibration and a loud whirling sound,you can get more help and real good prices at http://www.discount-merchant.com/?click=52978 good luck and keep us posted

Loud noise

I believe it is the color wheel. The motor might be going bad or it has dirt or dust in it.

I hope this helps
