Agreed. I returned my 6700 for the 7600 (see post a few up on this page) and the 7600 is a much better overall unit. For the $98 difference it was a no brainer. I also did the screw trick that someone got harassed for earlier and it totally works. My edge bleed is almost non existent. I had light bleed at the top center and right that was driving me crazy with letterbox movies. My screen "creaked" when cleaning it out of the box if you applied any pressure to it. I am not a technician by any means. I don't build tvs and have never opened one but here is my amateur opinion:
These new sets are extremely thin as it the screen material. I noticed just when cleaning the fingerprints with microfiber after installing it that there is much more give to the screen with minimal pressure that any of my other LCD sets. I don't believe in "massaging" the screen or putting any excessive pressure on it. Once again, I just noticed this while using minimal pressure to clean the fingerprints from mounting it. Basically, I started by turning one of the back panel screws directly behind where the bleed was about one or two turns to loosen it. The bleed changed. As I tightened it back down, the bleed would reappear. Now, I don't want to leave loose screws hanging around, so i loosened the adjacent screws on each side, immediate left and immediate right, and depending on the order in which I retightened them, the bleed would reappear or stay diminished. Long story short, I loosened each of the screws along my top row only one or two turns. Through trial and error and seeing how the uniformity responded to the order in which I retightened them, I was able to get rid of almost all of my bleed. Now, if you push hard on the panel when cleaning it, you will undo what you have just done. It is almost as if when the panel is installed, if it is not 100% perfect with the pressure across the entire panel, you will have bleed. With local dimming off, it is still noticeable, but the local dimming totally removes it from my normal viewing.
IMO, this is not screwing with my warranty or the integrity of my set. I am not opening it or breaking any type of seal. I am not modifying it in any way. I am not endorsing this method, but I was on my 7th (I think) tv and I was just getting to the end of my rope with all of the manufacturing issues. As of now, I am 100% happy with the picture. I have bright and dark room settings and minimal edge bleed. My set had very good uniformity out of the box with mainly the bleed being the problem. You do have to be careful, though. I initially made mine worse until I figured out what I was doing.Edited by cjsiv - 8/11/12 at 9:11am
