I just got a Panasonic CT-36HL43 and I am noticing an odd issue with the picture. It is most noticable on 4:3 DVDs where the black letterbox bars meet the color image. The issue is that on many scenes where the images has a lighter colored area, there is a thin white line where the black bar meets the color. It is on both the top and bottom of the image. The images seems fine and I have never seen anything odd in it. It is just distracting to see it and I know it should not be there. My set does not do anamorphic compression on signals less than 1080i (which is really too bad), but I don't think this would cure the problem. I suspect it is a result of some sort of line doubling. Any help, tips or advice would be greatly appreciated. I do not want to ship this back for service. Thank you!
