Not if there is a glow at the base of the tubes. That's just incorrect advice.
As I mentioned before, you now have to get in there with a meter and measure voltages to see where you are missing a signal from.

Would you please to explain " 6 volt supply coming from the main power supply (SMPS) that goes to each 762292 board to supply the filament voltage"...which one cable should be checking
Thank you

That cable would be for video not a cable for voltages. The cables that carry voltage are located at the other connector that runs from the mother board (Frame) to that RGB amp. They are usually yellow wires on Barco projectors (except 9 series). I don't have a manual for that projector so I can't say which wire it would be.
Having said the above (and I don't know what other discussions you have had) its also possible that the issue is related to the video circuit so do you have any spares to swap out including a SMPS a RGB input and RGB driver boards?

Check for bend pins. Sometimes when you insert the neckboard one pin does not go into one hole and it bends.
