There is a paper protection around the bulb and glued to the chasis on my set. You have to be quite careful in removing the paper and it takes a little time. After the paper is removed the bulb connected quite easily. The picture with the new bulb looks as good as when I first bought the TV. The expierence was not that difficult so Iwill buy another bulb when this one burns out. The bulb is rated for approximately 20,000 hours.
