I have recently started getting problem with my Samsung LNT4661FX 46" LCD TV. Actually, whenever I start the TV then at the start it shows black shadow which is in the 75% of the screen. Now if I switch off the TV and on it again then it usually not shows me. Basically it happens when I start the TV after a few hours. In between the play also, it shows that effect randomly. I searched for the solution of this but not get the working solution. Please help me with that.
