Humming sound from TV

My Philips 29" 2007 model TV is humming most of the time sirrespective of the volume of sound.

We can hear the humming even when the tv is muted or sound decresased to 0.

Observed same kind of humming with other tvs too earlier. I believe a solution exists.

Please help.

Thank you.

When turning up the volume speakers start to humn. Tried on all inputs still humming. Sound comes out but humming is there. Humming only stop when turning the volume all the way down.


You need to add a "ground lift" to the power cord to your system. What you're hearing is a 60 cycle hum (electricity) from house power.

Tv works but no sound


Hello Jjwpod hi, to find where the trouble is, you need to place ear near speakers, you should hear a humming sound, adjust the volume up or down, the humming sound also goes up or down, this means your amplifier is working, no hum means trouble in amplifier.
summary:
No hum: trouble in amplifier, speaker connection.
Humming, but no audio: problem before amplification, most likely the Sound IF stage.

Humming sound from new TV


Thank you for the info. I would suggest to take it back from where you bought it from if the store will allow a 90 days return and replace it for a new one, or you can contact Toshiba to get it fixed under warranty. There should not be any humming noise on the speakers.

Tv makes humming noise when on. how can I eliminate or reduce the nose?


Some of the larger TV's are DISH ready, meaning that they have the tuner inside for SAT TV. The SAT tuners often have an internal fan that makes a humming noise. If it sounds like something other than that, you might have a bad component in your sound circuit that allows 60 HZ hum through the speakers.


If it is a rear projection LCG TV it has a fan in it to cool the bulb. You will hear the fan if you listen closely. It usually cannot be heard over the volume.


The fluorescent bulb and electronics inside make humming sound naturally. Kinda like when you turn on a lamp, and some lamps make a low humming sound.
