The power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try www.projectordoctor.com
