Hello There!!!!!! Well this is gonna take some work... First thing to start with is... When you replace the bulb/s -does the bulb actually illuminate? If you shine a very bright light into the surface of the screen can you see a faint image of whats on the set? Do you get sound? If the bulb is illuminating, is it blowing soon after? Did the set return to normal operation after replacing the bulb the first time? Side Note-Never touch a high power bulb glass enclosure because you can leave oils and moister that lesson the life of the bulb or make it more prone to blowing. I have no facts to support this note beside my own experiences but this is a known "thing". Questions? Just ask. Mr.Mike
