Studio Beam will not Lamp

I have a studio beam that will not lamp...

I checked that it was not past the lamp limit... I also turned it off to make sure that was not the problem.

I have tried 2 separate lamps.
I replaced the Lamp Power supply, relay, line filter, and igniter from a know good light. It won't lamp... It shows the lamp light... then turns off.

Only thing I notice is that the fan's do not kick on when it starts up...

thinking it might be the control board?

Can any one help me out.
Thanks...
