Mitsubishi projection TV - no picture

I'm working on a Mitsubishi VS-4001R proj. TV for someone. It has great
sound, but no pix. The owner said the picture would come on by itself a
few hours after the set was turned on. The relay clicks and the power
supply appears te be running. I took the PS board out and checked all
the caps ( found two with high ESR which I replaced ) but that didn't
fix the problem. Would appreciate any service tips on this problem.

Do you have filament voltage?

I turned out the lights to check that and I couldn't see any glow from the
tube bases so I don't think there is any power there. ( can't get to it very
well with a meter )
