Plasma TV buzz/hum- anyone else?
So, I bought a 60" plasma TV a while back at Costco (LG, 1299.99- yeah, I know that's a lot but it was Christmas for the wife and I, and Borderlands split screen was phenomenal!) and it has started occasionally getting into spells where the hum/buzz is very loud from viewing distance. It sounds a lot like the low-level hum usually heard right at the back of the TV, only amplified, and changes level with the brightness of the image on the screen.
Anyone else experience this? Any thoughts on whether I should return it? (I am still within my 90 days at Costco). Hate to box it up and haul it back but don't want to spend this much on something that might have a problem.
