Lg tv humming noise when tv is on


The humming noise is most likely coming from the power supply.

If the unit is worth the repair cost ( Over $100.00 ) you should have it repaired.

If not, deal with the noise until it goes out.

Humming or squealing noise when tv is turned on (model 32LG30)


Be sure you have installed the stand scresw weather or not you are using the stand.
The back panel can vibrate without the screws.

Other sources of a hum are the coils on the power supply.
The power supply would have to be replaced to solve the issue.

I have a humming noise coming from my new 50in panasonic plasma tv. Is this a common problem and if so what could I do about it? Thank you for your time. Pat


The humming noise should be verry low . It is caused by the powersupply and switching fets on the boards. A plasma screen always produce some sort of humming noise when listen carefully to the device but it shouln't be anoying when enyoing a movie. So it is a natural thing but again it should not be noticable, enyoing a movie at apr. 3 meters or so...

TV made humming noise for past few months and after it warmed up the humming would go away. It that same thing today and a pop noise came and the screen will not come on, and the tv shuts off and then...


i took off the back and pulled out the the fan. Then put in a fat screw between a slight gap whick kept the fan from hitting what ever is causing the noise. probably not safe but nothing bad happened yet.

My lcd tv makes a humming noise


Try removing all cables going to the TV except the power cord. Power on the TV and press mute. If you have any unwanted noise, then you have a defective TV and since it is new, you should get an exchange. If there is no noise with the A/V cables removed, then you might have hooked the source (cable box/DVD Player) into the wrong inputs of the TV.

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.

Humming noise


Most times a humming noise in a Plasma tv is associated with high altitude. If you live over 3500 ft. and when you first turn on the unit is has a slight buzz and it gets worse as it warms up then you have what is referred to as high altitude sickness. You shoul contact the manufacture with this problem and the should exchange the unit with one tested for proper operation at high altitude. If you do not live at high altitude then there is a problem in the unit that should be diagnosed.
