I thought I'd let someone else chime in first; however, since nobody has for a week now. Here's the thread where you can get details on setting up service: http://forums.cnet.com/7723-13973_102-542437/service-issues-click-here-for-help/
TV is almost two years old. Just recently noticed a purplish band about 3-4 inches wide across the top of the TV screen against scenes with a white background. Did some internet searches and found that this seems to be a common problem with Samsung plasmas. Will require replacement of the panel for $995 which is what I paid for the TV originally. Definitely will not go with Samsung again if I have to replace this one after only two years. Anyone else have this issue and how was it resolved?
