I have a Canon LV-7325 Projector and just replaced the lamp. It powered up and stayed lit for about 2 minutes then shut off. While it was on the images were in Black and White. Try to start back up then it just would stay on for 10-15 sec. Now it just trys to fire and nothing happens. Please any thought would be great. If it is a part like a ballast (read in another post) or something else please advise on where to get new parts. Thanks, JD
