I have a burn in from black bars on both sides of my Samsung 5054. The problem is though that the ghost mark from the black bar on the right is far more pronounced than the one on the left. The one on the left would not be noticeable had it not been that I looked for it after seeing the one on the right.

I've switched my DVR to stretch the 4/3 signal so this won't be exacerbated further, but could it be something else in addition to burn in why one of the bars is more pronounced than the other one?
