The sound is generated by the power source - it doesn't run smoothly because either it's defective (but 2 tv with the exact same defect one after the other is quite improbable) or you have a very bad mains power line, filled with interferences. Plug the tv thru a mains filter then check the voltage - if it's at 120 volts as it should and the sound is still there then return this tv also - you are really one of the unluckiest men alive.

A constant buzzing might be interference from the power control card. What happens if you move the set elsewhere. Also, try it on another aerial, maybe there is a problem there....perhaps

Speakers had a buzzing/vibrating noise. had them replaced. still making same noise. happens on very low and loud volume. any idea what it could be? possibly the sound board?


maybe just poor speakers.....had a similar problem with an old sony. Replaced the speakers twice and always had a noticeable buzzing. Try running external speakers (computer speakers will work) at low volume to see if you hear it in those. If so, you may have sound board issue.

LG 37LG30 HDMI no sound problem


This is more probably a software fault within the TV. They need instructions for HDMI inputs & a no sound is a related fault. I would get in touch with your dealer to arrange the TV to be updated to cure this problem. Hope this helps.

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.
