Question about LG 42PG20 42 in. Plasma HDTV
Hi, I just purchased a 42" plasma around 2 months ago and all of a sudden im hearing a loud humming coming from the back. the sound comes and goes but it mostly comes. It does go away for some time if i tap the back. what is this sound?
Sounds like your powerboard, you can try a cheap fix by putting a small fan behind the tv on low and see if that helps. Also I would not settle for this and call in the warranty and get it fixed while you can.
