Funny noise on LG TV

Hi, I've had my TV just over a year and this seems to be getting worse. It is a 37" LCD LG and has a great picture. The problem is the sound, it seems to have a slight background high pit noise that comes and goes, recently it has been there more often than not. If it is on mute I can still hear this noise. Please help as it's driving me mad!! Thanks

This is a problem with alot of TV sets. Most of the time, women can hear this alot better then men because they have better hearing then men. There is what we call in the buisness, a "singing coil". The problem could be simply the coil is singing and will need to be replaced because the windings of wire that makes up the coil is not wrapped tight enough or this noise could be the sign of future problems to come as a bad switching power supply capacitor or a capacitor going bad. I am sorry to say there is not alot an end user can do except call out a tech to have a look. Good Luck

37" Philips LCD no sound.


Maybe the antenna that you are using is not picking up sound from the channels. It could also be the cable. If it makes a humming noise, it means that the speakers are getting electric current and that they SHOULD be okay. It also could be your tuner. Maybe check it all out at some tech place like best buy. Those guys can help

Cracking noise SAMSUNG LCD TV


I wouldn't recommend doing anything yourself because you can easily make the problem worse. I would recommend calling samsung because it's been under a year and see if they cover the problem. If you open the tv, that could void the warranty so I would try samsung before doing anything to it.
