Lg tv humming noise when tv is on

It is coming from the lower back of the tv, and is not very loud, but loud enough to be annoying... How can I fix it? Also, the tv is over three years old, and I don't think is is in warranty... The noise did not get better when the tv is muted, so I don't think it is a sound issue.

The humming noise is most likely coming from the power supply.

If the unit is worth the repair cost ( Over $100.00 ) you should have it repaired.

If not, deal with the noise until it goes out.

I think that the pop you heard was an electrolytic capacitor blowing its top on the picture frame board. If you are able to check this for yourself by looking on the board for the one/s with a bulging top or are a brownish/black colour like something has caught fire. And also in this situation smell can be of great help as it will smell burnt out but PLEASE before putting your nose or anything else in the tv take all necessary precautions against electric shock and discharge any electrolytic capacitors in the vicinity. If you are not able to do this yourself find a competant technician. Hope this helps.

SOURCE: my lcd tv makes a humming noise

Try removing all cables going to the TV except the power cord. Power on the TV and press mute. If you have any unwanted noise, then you have a defective TV and since it is new, you should get an exchange. If there is no noise with the A/V cables removed, then you might have hooked the source (cable box/DVD Player) into the wrong inputs of the TV.

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.

Humming from back of tv


sounds like your powerboard, you can try a cheap fix by putting a small fan behind the tv on low and see if that helps. Also I would not settle for this and call in the warranty and get it fixed while you can.

Dishwasher making loud humming noise


The most common cause of the hum/grinding sound, and often poor cleaning - is a blocked filter or debris stuck below that filter.
Pretty easy fix: Get a phillips screwdriver near by. Pull out the lower rack (the upper rack can come out if you pull the little gray thingeys on the front of the upper rails.)
Remove the lower spray arm -- just pull it straight up. Remove nine silver screws from the sump area that holds the filter down. Pull the filter up and out. Rinse the filter as best you can.
While the filter removed, with a flash light inspect all over the sump area - looking for stuff that should not be there and clean it out. Watch out for broken glass!
Replace the filter, screws and the spray arm. Fire it up and check your results!
Good Luck!

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.

GE SidexSide PSS26SGPASS Makes Humming Noise


GE refrigs have a variable speed evaporator fan motor that is controlled by a computer board on the back of the refrig. now the noise you are hearing is most likely the fan motor ramping up and down in speed (some of my customers say it sounds like a ghost). if its a continuous ramping up and down then the speed cotroller on the board is bad and must be replaced. if its just an occasional sound then thats normal and nothing to worry over.

Btw the reason the noise stops when the door opens is because the fan shuts off when you open the door.

Occasional 'whistling/whining' from back of TV


I wonder if there is enough air circulating around your equipment?? My DVD recorder makes a sound unless I open the doors on the cabinet that contains all of my equipment. The cable company says it is a fan to cool down the units.
