Hi I have a 3 year old HL-P4674W Samsung DLP. Recently the picture on this set has been looking terrible. Its hard to explain the issue. On subtle color changes there is not a smooth transition, and it is very visible on large areas of dark or light colors. Night scenes or peoples faces appear to have "rings" of different colors. I had a tech come out and look at it and he said it is just noise in the signal and said there is nothing wrong with the set, but i tend to disagree as i see it on every input source, like cable or DVD. I replaced every cable in the system, and replaced the lamp just in case, but this has not helped. Are there any other user-replaceable parts that could be causing this problem? Or is it just my eyes getting old? I SWEAR that it never looked like this before..
