It may be the device(cable box, game system ?? ) connected to the tv has a volume control as well and that devices volume control is set very low. is dvd or vcr input fine? Is this connected to a computer, then check the volume control on the computer.

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.

I have no audio


Hello sir, Hi, No Audio on your TV can be user error or Hardware error, for the user error, make sure that the TV is not set to low volume or the setup is on MUTE, for the hardware error, Place your ear close to the speakers, then set the volume up and down several times, you should hear a soft hum that goes up or down, (make sure that the room is quiet.) The soft hum means that the power amplifier is working properly. so the problem may be on the main board where the sound is being produce before amplification, usually the sound IF section. NOW if you did not hear the soft hum, problem with the amplifier and speakers, A physical checking for open wire contact or loose connection is needed.

Hum from tv


try unplugging any equipment that you have attached to the tv one at a time, such as dvd players, surround sound, cable box, etc. also if you have a cable box attached, try adjusting the volume on it. if you have everything unplugged from tv and it still hums, then it may be a tv issue

Low volume output and very low volume when digital broadcast


if you are using a digital converter along with a standard tv , you have one volume level low making the unbalance sound a humming sound, if it is directlly into your tv, check your settings on your tv bass, trebile, by the sound of it you probably have a digital converter , if this is so, raise the volume of your TV to mid point that raise /lower your volume on the converter and it should be fine, also make sure your ouput channel is not the same as your broadcast channel in your area, example,,if your area uses channel 3 for broadcast, set your rf output to chann 4 , and vice versa.

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.
