I've read some of the posts on this projector and some of the similar ones but because I'm a complete amateur I still have no idea what I am doing. I have a Lp530 projector which has burned its bulb in less than a 100 hours. I can find a cheap replacement bulb but from what I've been reading there is a problem with the projector causing it to overheat or ruin the bulb to fast and there was a fix given by infocus which is not available anymore. If anyone can give me a broken down step to fix this problem before I rush and buy a bulb I would GREATLY appreciate it. Thanks.
