Question about LG 32LC7DC 32 in. LCD HDTV
My new LG 42" LCD TV is making a buzzing sound that has become really annoying. It started a couple of days after I got it. The only way that I've figured out how to reduce the noise is by turning the backlight all the way up to 100. Even after doing this it still hums when the screen goes all black.
Is this a common problem with LG LCD TV's? Should I return the TV and get a new one, or is there a way to fix this?
Please let me know as soon as possible
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.
