I bought an olevia LCD tv from circuit city about a week ago. Happy with it, got a good deal (wii looks great on it), but I've noticed something that is worrying me. This is my first LCD TV, so I don't know if it is normal, but I keep hearing a clicking noise coming from the TV. The noise happens when the TV is on and shortly after it was on. Its regular but not constant. Is this normal for an LCD, or should I return it while I still can?
