Please, let me reiterate...my RPTV is properly calibrated using Avia. All of my modes and inputs have been calibrated. Contrast has been adjusted properly. No, I did not watch more than the recommended amount of 4:3 material.
The difference between these black bars and those of a 2.35:1 dvd are the source of the black bar, and the image edges. If you have not watched 4:3 material that is broadcast digitally by the networks over the Motorola 5100, then you do not understand. With the 5100 in 1080i, letterbox mode, the 4:3 display gets black bars on the sides. Stretch modes do not help b/c the bars are part of the image and are treated as such and stretched themselves. These "black bars" are far from the "clean" black bars you get when you watch a DVD in 2.35:1 aspect ratio. I'm not sure whether the black part is broadcast by the networks or created by the cable box itself. The edges of the image are not clean. There is flickering, brightness, and an uneven image where the edge of the picture becomes the "black bars". I believe it is these edges that cause the problem. The burn-in I have is not serious, as it is only visible in some scenes where the image, colors, and brightness is right. Often in dark scenes the lines are visible...not bad, but noticeable. I hope that over time as the CRT's get used more and more, the image will even out and the lines will become less visible. I believe that they have already faded somewhat. I almost never watch 4:3 material on the digital channels, and when I do I go through the annoying routine of switching the 5100 to 480i mode, pan and scan. This allows me to chop of the edges of the picture and replace them with gray bars created by my TV. This method is safe in my opinion.
I post this only to warn people that it is POSSIBLE to get burn-in regardless of how well you calibrate your system. I don't want people to think that it is something to worry about either, just something that can happen if you don't take the right precautions. One of those precautions happens to be NOT watching 4:3 digital broadcasts.
If you don't believe me, thats fine...but the proof is on my TV. Just do others a favor and do not preach that burn-in cannot occur on a properly calibrated set. There are other factors in place that you may not be aware of.
Bottom line: Don't watch 4:3 digital broadcasts with the black bars. Either switch to the pan and scan mode to allow your TV to add its own bars or watch the analog broadcast.
