I have a 7 year old 55" Samsung LCD HDTV that has the dreaded white spots all over the screen. Samsung refuses to recall the model I have so trying to decide what to do with it. I understand the computer chip that has to be replaced is almost as much as the cost of replacing the TV. Has anyone here had this issue with their TV and if so what did you do? I'm getting ready to trash and replace the Samsung and since this forum has such a large contingent of experts this would be a good place to check.
