Bobgary, I believe the waveforms you posted correspond to an old Hickok generator, which had full field bars, but not in the modern order according to luma level. Also, once things are reasonably close, it's much easier to check if these color difference signals are exactly correct by looking at the R,G,B waveforms (if available) or looking at the picture through colored filters, or turning off two guns at a time. (Professional monitors will send the blue-only signal to all three guns so you can see blue as monochrome.)
Pete, I don't have a schematic in front of me, but you said the matrix is all fixed resistors. I thought I recalled an "I gain" adjustment in there somewhere?
