Very loud fan or vibration noise

Turned on TV today to hear an awful loud buzzing noise - not from speakers - like a fan or bad vibration. Set was fine day before; was not moved, bumped, etc. It is approximately 2 years old.

Re: Very loud fan or vibration noise

Listen from the back of the TV and locate the source of the noise. There may be fan with a bad bearing. The noise will lead you to it.

U can't the buzzing noises are comming from the tv power supply board itself have some short of problems on it high voltage transformers parts,not easy to get rid of,must know how to troubleshoot and replaced electronic components parts to fixed it.The simpliest way just do a replacement of the whole power supply board,that the board where the power a/c cord plug into it.Tries websites like, to buy a whole refurbish power supply board for the replacement.

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.

Speakers had a buzzing/vibrating noise. had them replaced. still making same noise. happens on very low and loud volume. any idea what it could be? possibly the sound board?

maybe just poor speakers.....had a similar problem with an old sony. Replaced the speakers twice and always had a noticeable buzzing. Try running external speakers (computer speakers will work) at low volume to see if you hear it in those. If so, you may have sound board issue.

A buzzing noise coming from inside the tv but still buzzes when on mute but doesnt buzz when tv guide is up on the screen or when a channel is showing what time it starts

plasma tvs buzz a lot, depending on screen brightness. its probably normal but if you can hear loudly over your volume, may be a bad board or plasma panel. from behind tv, left side = y board, right side = z board, middle = power board ---- bad panel can buzz from anywhere... if you hear all parts buzzing, its probably normal plasma noise

Set was on and made a loud pop noise and the picture went off. the red light was flashing and no picture. then it made a strange buzzing type of sound a few times. turned off for a couple mins and then...

It sounds like your screen inverter has just gone >bang< unfortunately.
Most screens inside use 2 main circuit boards, and you are most likely going to have to change one of them.
It's possible also for it to have been just the backlight bulb making the loud pop noise too. The inverter may have given out too much power and blown the bulb (a lot like you hear when a house bulb goes bang).

If you can't actually hear any TV sounds (normal sounds like music, voices etc. when they should be there), then it means the problem is more serious, and would need a specialist repair place to check out the electrical circuit inside.

LG flat screen TV speakers make a vibrating noise

I have this problem with my 37LG30.
They all seem to have the same factory flaw.
The plastic bezel and rear is vibrating against itself I have found.

Tonight, just now, I just took all the front bezel screws out,(from the back) loosened the other 4 big screws in the rear center(I don't recommend removing them)and loosened the stand screws also and tried separating the bezel from the back as I went around the set. This did not really help much except around the bottom where the noise/vibrating comes from-the speaker area.
The two plastic pieces are vibrating against one another.
The vibrating was coming from the speaker area without doubt.
The next thing was to try separating at the bottom where the speakers are with my fingers and a stiff metal nail file carefully..fingers seemed to work best for me.
As I separated the front bezel from the rear housing (at the speaker location)most if not all the buzzing/vibrating /distortion went away.
I then inserted small pieces of cotton (you can use felt, or similar I suppose) and buttoned it all back up;put the screws in
Almost all the distortion and speaker buzz/vibratingis gone except on very low frequencies.
good luck!

Vizio speakers make a buzzing noise

It's not the speakers. I usually hear of this problem when hooked up to an HD cable box. You can adjust the volume on the cable box and also on the TV. I'll bet you don't have this problem when watching a DVD.

If the problem is what I think it is, your HD Cable box is set at a really low volume while your TV is set to a rather high volume. Try setting the TV volume to around one-third, then set the volume on the cable box until it's as loud as you'd ever want to hear it. With the TV at such a high volume, you're actually amplifying any stray electronic signals that the wires might be picking up, and the above solution will fix that.

Good Luck.

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.
