The TV is about 1 1/2 years old and the buzzing/humming sound has become quite noticeable. It does not change when you adjust the volume (it's the same even if the volume is muted).

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.

My whirlpool aide by side fridge icemaker is making buzzing or humming noise


Hello
Welcome to fixya.
I'm Huuum and happy to assist you,


You said, your ice maker is making a buzzing or humming noise ice maker isn't making much ice. . fridge is about 2 1/2 years old.

This sounds like a clogged water line or a electrical short !
I would get service rather than take a chance on electrical fire.
Or burn up the circuit in the ice maker.


Thank you for giving us the opportunity to advise you.

I have a Denon AVC 3030. In pro logic mode it makes a rumbling through my right and left speakers. During quiet parts of movies it is quite annoying. I know it's old but I really like it.


If what you mean is a low humming sound when the volume is turned down to minimum level, this is usually from power supply filtering problems. Most of the time this is from the electrolytic filter capacitors going out of spec with age and use, and or voltage retulation problems.

If the sound is quiet with the volume turned down, and the hum or buzz increases with the increase of the volume control, this is usualy due to a ground loop problem between the associated equipment connected to the amplifier, or a bad interconnect cable.

The noise from the TV is called 60 cycle hum and it is caused by a capacitor that is open, a test for ripple voltage will confirm this The noise from the VCR is more then likely common mode noise which would not be heard but for the bad capacitors in the TV. Simply put the common mode noise is being added to the 60 cycle hum. Now for how to fix this, if you have a background in electronics you can use a schematic, multimeter and an oscilloscope and Multimeter to find the bad capacitors, and the schematic to tell you what the voltages and %ripple should be. If you do not have a background in electronics, take the set to be repaired
