I received my Kp43ht20 last week and have noticed a little red and green around hard lines and movement in the far right 3/4 inch of the screen from top to bottom. The rest of the picture is awesome. Is this an easily fixable convergence problem, or something more severe? I have a Sony tech coming out Monday but wonder if I should send the set back for a replacement. Like I said it's minor, but noticeable (My roomate noticed right away while just watching the Laker game.) I'd hate to send something back which can be fixed quickly and end up getting a bum set in exchange. Also, What should I look for when the Sony tech works on it? Any comments and help would be appreciated. My first RPTV.
