Hey, I just got my 73638. I bought it used, so I have no warranty, or anything like that. I have notice an issue with it, and I'm trying to fix it, but I don't know how to. I've tried the service menu, and calibrating it like that, but none of it helped. The problem that I am having is that my image looks to be doubled in some places on the TV. There are 2 vertical bars, each about 8" from the left and right side where the picture is pretty blurry, but is clear on the very edges of the screen, and also in a semi circle on the top of the screen. It has been pointed out to me, and now it is bugging me. If anyone has any ideas, please let me know.
