Question about LG 37LC7D 37 in. LCD HDTV
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.
