I have a LG 47 inch 3D LED TV which was bought couple of years back. It works well and no problem with that. However, I noticed recently there is a thin logo of a news channel imprinted to the left bottom corner of the TV. Even when the channel is changed there is a faint impression of the logo visible in the next channel. I thought this kind of burn-in will happen only in Plasma Tv's but surprised when it happened in LED TV. It does not hinder the viewing but how do I get rid of it.
