Re: Buzzing sound coming from TV

Sounds like a power supply, could be a large capacitor or a large transformer making the noise

Tv making loud buzzing noise

A common cause are failure of decopling capacitors in the audio section, and or the circuit board power distribution that feeds the audio board. Most of the capacitors are surface mount components. The standard fix is to start by changing the circuit boards that have the defective parts.

If the set is under warranty, call for warranty service. Out of warranty service is expensive for these TV sets.

Today I bought SONY KDL37EX402 LCD TV. Immediately when I turned it for the first time I noticed an unpleasant sound like a ?buzzzzzz? from the back of the TV. As I worked it for more then 5 hours I...

I'm pretty sure that the buzzing sound is a not normal thing for an LCD TV. I sell Flat Panels during my spare time and it should be as quiet as a CRT types. It is more likely a defect and you should return it ASAP.
Hope this helps.

Hi, I Purchased an LG 50PK350 plasma tv and I am experiencing an extremely loud, annoying buzzing sound even with the amp switched off & the sound muted. The buzzing is not constant ... the brighter...

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.

Samsung P237HD tv/monitor,unit buzzing when on.

I would take it back unless you have time to investigate the problem before the return policy expires.

If the sound is coming from the speakers then it is interference and would likely happen with another TV.

The interference type can be electromagnetic or radio frequency, both of which can be defeated.
Start with plugging it into a different outlet. If that doesn't work, then unplug anything from it one device at a time to see which thing is the culprit. If it is one of the devices, move any audio cords away from power cords and/or position the device further from the television.
Household appliances and fluorescent lighting also can cause signal interference in electronics that is audible.
A device known to help with such interference are power line conditioners from such brands as Tripp lite, and ferrite clamps. You can place ferrite clamps on the power cords of your devices and their analog audio connectors.

Vizio GV42l buzzing

Vizio makes an ok LCD, but if you notice they no longer make plasma. they stopped last year. Anyways. the buzzing sound is semi serious, it sounds as though you have a capacitor leaking. It is best to get it fixed before it goes out all the way, with it buzzing it will be easier to identify. Best of luck

Koss KLD2700 LCD TV no picture
As in almost all lcd type tv/monitor the backlight will go out and the inverter should be replaced at the same time. Your cost about 50.00 if you do it yourself.

Take care
