I know that you already know this, but i will say it in case you don't. Crt projectors usually have switches to turn off individual crt's during the set up and alignment process. sometimes a previous person might have flipped switches just because they can. Also Does the green crt filament light up? swapping out the crt boards is also a great idea as mentioned before.
