Vidikron Vision Model 40 will not power on

[Solid_State]

I was given a Vidikron Vision Model 40 HD DLP projector

The only information I have for its prior use is it was mounted on the ceiling and they were using RS232 commands to turn on/off the unit so the hard power switch was never touched.

The power LED is supposed to light orange upon receiving AC power however that does not happen the unit is totally dead.

I checked the AC line fuse and the lamp interlock switch and both check out fine (Both have continuity).

Should I check the hard off power switch?

I did not do that when I had the unit apart.

I don't think that would be bad though as it was in the on position when I got the unit and the switch feels fine.

Also the lamp look fine (as in the arc-tube is not all black it is still relativity clear). I do not know how to check the lamp other then the visual inspection that I already did

Thanks
