I have a 15" sharp aquos LCD Tv that I was using with ear plugs when working out. I began getting electric shocks in my ear. After four phone calls to sharp, and talking to four representatives they finally agreed this was dangerous and sent me a new 19:" TV (I returned the old one to them but never heard from them about it).
The new TV went dead in 3 months. They asked us to send it back to them (at our expense) and said they would "diagnose" the problem on this brand new TV for $50. We then received a call (after 3 weeks) that it would be $268 to fix this brand new TV.
