Shuts off after using it for a while....Eiki LC-NB2UW

broken bulb or failing ballast unit

Google it

Check the lamp. If it is not blown then there is a problem in the lamp ballast circuit and the projector will need to be serviced.

may be overheating. blow out the projector with canned air. the dust keeps in the heat that the projector is trying to expell. also check the lamp for bulges and dark spots. if you have any of those, replace the lamp. if the lamp is new, check the colorwheel for a high-pitched whir. if you don't hear it, replace the colorwheel. otherwise, replace the ballast.

check the lamp for black spots and bulges. if you have any, replace it. if not, you have a ballast/power supply issue.

simple!!! (if you know it..)
press the UP button on the projector for 20 seconds, and the hours used will be displayed briefly in the left upper corner of the screen.

Found the solution on Eiki web site, in FAQ section.

Hi sjmuseum

If you cannot find the advanced option in the standard users menu , then it will only be in the Service Menu which you would have to call Eiki support to find out how to enter the Service Menu.

I use it for my xbox 360 for both streamed movies and those I buy on DVD and to be honest it beats any glass tube you can buy. I have been really impressed with my but I do not like how they justify a 300 dollar price tag for lamp replacements. Just can't seem to figure out why any light bulb would cost more than 20 bucks. But hey maybe I am old fashioned :) YES it's beautiful for movies, course it's the only projector I have watched them with.

does the remote control works for other functions ?? if no try to make factory reset setting through out settings menu
