My parents just gave me thier old 27 inch sony LCD tv which has developed a smudge/smear (Black) which gets worse the longer the tv stays on. It looks a bit like a blur/smoke similar to if you press an LCD screen but its not. Its about 1/3 way down from top and, at its worse is about 8 inches long and variable to an inch wide.
Anyone have any idea what it is, how to fix etc?
