Question about LG 42LC2D 42 in. LCD HDTV
46 inch LG HD flat screen TV the speakers seem to have a slight vibration that distorts the voices. It does not occur with every word but often enough to be a pain.
I have this problem with my 37LG30.
They all seem to have the same factory flaw.
The plastic bezel and rear is vibrating against itself I have found.
Tonight, just now, I just took all the front bezel screws out,(from the back) loosened the other 4 big screws in the rear center(I don't recommend removing them)and loosened the stand screws also and tried separating the bezel from the back as I went around the set. This did not really help much except around the bottom where the noise/vibrating comes from-the speaker area.
The two plastic pieces are vibrating against one another.
The vibrating was coming from the speaker area without doubt.
The next thing was to try separating at the bottom where the speakers are with my fingers and a stiff metal nail file carefully..fingers seemed to work best for me.
As I separated the front bezel from the rear housing (at the speaker location)most if not all the buzzing/vibrating /distortion went away.
I then inserted small pieces of cotton (you can use felt, or similar I suppose) and buttoned it all back up;put the screws in
Almost all the distortion and speaker buzz/vibratingis gone except on very low frequencies.

How to stop LG tv speakers vibrating?
It's not as simple as it sounds is it because the cabinet is supposed to resonate by design. I have a workaround which works for my set
If you think about it, the Cinema default EQ setting already increases Bass at default from flat.
Then if you consider SRS Trusurround also adds Bass too therefore You're already going to give the tiny tv speakers a good going over even at relatively low volumes.
Couple that with Freesat (which on my set is louder than all the other inputs) and then throw in BBC HD which has decent audio and it's probably no wonder it's crying at me with this vibration/buzzing.
So what I've done is tweaked the Cinema setting as follows:
SRS Trusurround : on (widens the soundstage nicely with these below on mine).
Auto volume: off
80hz = (0)
220hz = (-1)
470hz = (0)
1khz = -(1)
I appreciate different room sizes/environments etc, but I honestly have it at 40 volume for the first time with no distortion. It's also giving me decent levels of bass and treble after trying in addition to BBC HD, Clubland tv, FIVE to give me the broadest samples of broadcast content/sound levels.
My work here is done..Call me Zane

You can try to connect a headphone and listening if you hear the same distortion.
If not, there could me a resonance in the housing of your TV or blown up speakers.

I have a wall mounted 60" lg. Same problem. Stuck a shirt and sock (per another recommendation) back there where the rear metal housing was vibrating and all is well.
