    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!

    Your contrast ("picture" in Panasonic nomenclature) and brightness are set too high when you're screening a film wider than 1.78:1. Reduce the contrast level so that the inner dead space merges seamlessly with the rest of the unused portion of the screen (these are not "bars"; nothing is being obscured).

    If the Panasonic doesn't do 480p in a 16:9 window for 16:9-encoded DVDs, can't you convert the signal to 1080i to watch them in a proper 16:9 window?

    Jack,
    I too see the line on 2 of my TVs, and my set is calibrated using Video Essentials.

    Yes, that is my current plan, to get a Samsung HDTV STB and upsonvert to 1080i so that I can view 16:9 using the anamorphic compression. I did figure out how to get rid of the white line...I set my DVD to progressive (which I thought I had already done) and it was gone. Still there on TV and video games, but I will see if that improves with the STB also. I appreciate the tip on the controls being set wrong, but I think it was something else. My set was also calibrated with Avia, so I think it was pretty decent...

    Thanks!

    So you're both seeing a single, thin white line? And in Jeff's situation the line disappears when the DVD player does the deinterlacing. Weird.

    Yes, it was very strange, but I changed it back and forth to verify and sure enough. I wonder if it has to do with some sort of line-doubling? I have no idea...
