My tv is making a loud ringing noise off and on. What can it be? My sound is connected to Surround sound and therefore have the internal sound off but that is where the ringing is coming from

  • Anonymous May 11, 2010

    question one.. if i understand you.. does the ringing occur in the speakers of the tv? Is this more an internal high pitch wine.... I have seen cases where there is a component where there is a component called a coil that begins to vibrate.

Panasonic TV does not play through surround speakers

so it is a connections problem I think. Check if video and audio cables are properly connected. Use color codes as your guide. Also from menu check if all settings are ok. Good luck

My vizio tv is practically brand new as of christmas, when a movie or even tv is on the voices are very soft and the music or background noises are EXTREMELY loud, so I am always turning the volume up and...

I had this problem with my previous TV (Syntax by Olevia, an off brand). It only happened to me on certain channels, and for certain shows. What is happening is the TV station is broadcasting the audio in Dolby 5.1 format. For some stupid reason, the TV is playing the background speakers (effects) instead of the speaking parts. You get a little bleed-over of the voices into the back speakers, so voices are there but really quiet. Unfortunately my TV didn't have any surround sound options to fix this.

See if your TV has a surround sound option. Otherwise, you will need to connect the TV sound output to a surround sound system that can properly decode the audio channels.

BOSE 38-WHITE BACK:ERROR 801-LOUD SCRITCHING NOISE AFTER SHUT OFF

Hello any cable or satelite tv show is now more comonly in high definition sound and video! and the techs are wrong because their are plenty of movies on tv including news channels that broadcast in surround sound ,but in order to get that surround sound you must either have a connection from the tv,s audio out or you can also out put the sound from the cable or satelite box out to your bose system as as the scritching sound where does it only happen when in surround mode or stereo mode ? if you play a dvd or cd does it still make noise? and can you be more specific on your terminology SCRITCHING not really shure what you mean by that word! thank you glenn mayer

Background sound too loud

Thank you, everyone! I thought maybe I was losing my mind. I can hardly watch a lot of the TV shows anymore due to the inappropriate use of music -- either it's too loud or there's just too darned much of it. Come on, TV producers! You are supposed to get better with time, not worse! Thank goodness I'm not alone.

Emerson dvd player - background sound lauder than dialogue

Greetings surfjax,

If you will allow me to make an assumption, you do not have a 5.1 surround system connected to your DVD player. This is a common experience with users of a standard TV or stereo receiver if a movie is being presented in 5.1.

In a surround sound system the center channel speaker provides almost all the vocal tracks while the side channels will provide music and some background noises. You'll still be able to hear the voices in your side speakers, but it will be muted and over powered by music or sound effects.

Some DVD players allow you to "Downmix" the surround signal to stereo. You might want to look around your sound setup on the DVD player or check your owners manual.

Hope this helps.

Surround sound

to connect audio from tv to receiver.Use the monitor out(audio) from tv to receiver .The tv will only put out left/right audio .Also when using the audio out from Sony tv sometimes you cannot use both the internal speakers from tv and audio out from tv to receiver at the same time..Make sure audio is set up on TV menu for audio out..

Loud Humming

It's possible a fan or a hard drive is going bad. When the bearings in those devices start to go out they a start making noises like that.
