its actually super easy. what you need to do is head down to the beach and gather a bucket of sand. remove the bulb & fill it with said sand. re-attatch the bulb and there you have it. problem solved.
I've replaced the bulb on one of my tv's twice now. It's a Sony. All I did was Google the the tv model # and a few sites sold the after market bulbs cheaper than Sony did on their site. I think I paid $120 for it
