As long as the pattern has all three colors, you should SEE all three colors ON THE SCREEN, but if the pattern is not the one specified in the service manual, the waveforms will be different from the service manual.
I have a blu-ray player with composite output and will run it into the RF converter. This way I can use the Spears & Munsil calibration disc that has a number of different color bars. There is one that has all the color bars.
