suddenly my blue tube does not spit out any light while watching a movie. i've turned the machine of a few times and after a few tries it worked profoundly again.... now when i turned the machine on i does not work. i can see that it gloes at the tube neck just as the other tubes but the phosfor doen not lighten up... what shuld i check? is it broke? the green and red looks as good as usual. i have not noticed any strange things at all before this
its a marquee 9500lc ultra projector

Hello
Put up a test pattern and see if blue lights up, if it does you might have a source or cable issue.

Tim's right. You should check your cables first. Re-seat the blue BNC on the projector first then the connector at the source. I find that I have less trouble if I re-seat all my connections at least once a year. Don't start taking the projector apart untill you are sure the problem is not external.

Besides, Marquees are bullit proof. I know. I tried to shoot one once. But don't be confused. The Marquee didn't deflect the bullits, the bullits rejected the Marquee

hahahaha, cool! first i unpledged just the source(ps3) but the problem was still there. then i've turned tje projector of and unpledged the cables atatched to the projector and the device gamma x(this gamma device could have been damaged once). now when i've started up it worked! i've reconnected the ps3 and it works... i'm not certain that the problem will not come back. but i hope that the problem is not to serious because i'm not competent for doin to advanced tecnincal stuff
thank you all for your time on this
