Hi, first time posting hear, great site. I'm in the process of purchasing a projector for my "value minded" home theater project. I've found this great projector, a used Panasonic PT-L6600U for an awesome price. The only problem is that the owner says that there is lots of blue in the picture. He said that he received a message saying that the bulbs needed replacement. Do you guys think it's only a bulb or setting problem or should I stay away from it. thanks guys
