Guys - what can cause missing colors on the color pattern test.. I can not get above those 3 bars no matter what I do on the RGB gains front dial..

It looks like you have your gains maxed out and the cutoffs at the lowest setting? Set all the pots back to the middle position (brightness, contrast, cutoffs and gains), and turn up the voltage on the flyback (of the two pots, it's the lower one, possibly has the text SCREEN next to it).
 
Guys thank you for the replay.. I tried it and got it improved..not perfect but better..:)
