My 52hm84 is about 5 months old and has been a very good performer overall. One interesting problem, though, is when I'm on a 4:3 program with the gray side bars, the bar on the left has a black bar about an inch wide along the right edge. It's only on the left side. When I adjusted the set using VE, I did notice that there is a slight right shift to the picture (probably a couple of inches). This isn't noticeable on program material, but could this be contributing to my double side bar? Does anyone know how to adjust the centering of the picture using the service menu? Thanks everyone.
