    i have the same model & same electrical humming/ buzzing noise. it appears to be coming from the area where the power cable goes into the tv. funny thing is the noise tends to be present when watching through DTV input, AV1 input (sky box) & AV2 input (vcr) but is not present when playing nintendo wii through component input. i have had the panel 3 months but have only recently noticed the noise, but thats not to say it hasnt always been there.

Have you tried adjusting the contrast? , have a similar problem with a 42'' lcd and it appears to be related to the contrast setting .If is set my contrast below 90% the buzzing sound stops.
This buzzing sound seems to be a common problem with LG TV's

LG fridge making loud noise


Bonjour,

jeepers are we talking about a wheeze, a clunk, a whirr, a buzz, a rattle, a hum, random modulated or cyclic, low or high frequency, persistent or intermittent? Or could you just be hearing fan noise.
If it sounds like tin pieces clinking against something metallic. The fan blades may be striking ice or frost or the shroud.
Could be a bad or worn fan motor bearing, or a defrost problem causing frost build up.
Just a FYI
Some LG models have been reported online as having many many operating issues.

Hope this helps

How to fix sound on my lg 42


Some simple things you may already have tried but I will list:

Unplug set for a while and then plug back and see if sound--when unplugged the set may reset.

In main menu make sure speakers are not switched off.

I doubt it is mute but if also using some type of box check that its volume is not all the way down.

If internal speakers put your ear right to them---hear low sound or a buzz or hum?

If using external speakers of any kind look at the hookup and switch to make sure internal/external is correctly selected

If NONE of these help you have an audio problem and should first contact LG (yes it takes time on the phone) to inquire if some common issue or a possible software upgrade is available for this.

Last: Some failure has occurred either in the audio circuit or something that feeds it.

Lg lcd tv humming sound which varies throughout a programme no rhymn or reason to it but especially noticeable when quiet part of programme


Alot of Tv's have this sound that comes from the speakers or the back of the set. Its normally when the transformers inside are underload they start buzzing. this could come from the Powersupply or the Inverter. When changing channels they change their tone sometimes.

LG Voyager keyboard backlight broken


The connection between the keyboard and the mother board are loose. You need to take the phone apart and push the connection all the way back in. the connection is also connected to the screens and that might need a good push. Ive done this fix on many LG voyagers and enV's.

New 42LG30 - 42


This is probably a defect in the backlight inverter circuit. The transformer may have a loose winding or something in there is not cycling off or on properly. If you can still collect on the warranty, do so.
