Can you check the actual Tube run time? Should be hour meters for each tube.

you could go checking voltages on the rgb board.
barco has extra gamma circuits for red and blue, maybe something is wrong there.
yellow is red and green.
projecting a white field should reveal if something is wrong with the gamma circuit.

I certainly can check the voltages, as soon as I figure out how  . Checked the 17.5 volt, it was at 17.84 so I brought it to 17.49.
My concern now is that something other than the tube has gone bad. I don't know how to check individual tube run times, but it seems that if the red tube is dead at 7000 hours, something else is likely the culprit and replacing the tube may be a waste of money and time.
