Hi everyone got a KDFE50A12U delivered yesterday to replace my "broken" LG dlp rptv, but noticed that there is a mark on the screen just to the right of centre of the screen, it looks like a smudge or slighty darker patch about the size of a golf ball on the inside of the screen! Has anybody else has had the same thing on theres. I was wondering if this is normal or not before i call empire direct up to get a replacment. The only time i can see it is when the picture is dark or mostly red! Thanks in advance Dean.
