Question about LG 42LH30 42 in. LCD TV
I have a brand new LG 42LH30 TV and I've noticed a consistent humming, or buzzing sound coming from the set. It seems to be coming from the speakers. It's largely drowned out during programming, but is quite obvious during the split second silence that precedes a commercial. I can't imagine this is normal. Any advice?
Ur power supply board.Transformers have have high voltage gap.This problems must take the tv aparts put some glue arond the transformers,sometime solved this problems,or must replaced all the trnsformers make the humming noise.Brand new tv take it back,where u bought it get a replacement or call the Manufacture help to fix the problems or replaced the part that cause the problem.
