heres what I am working with, this is with the brightness turned all the way down. checked and swapped out x303,304. changed out the bi polars and c302, checked D301 and was fine, swapped out the flyback and the screen and focus board. swapped out the neck board, B+ is 119 so its not being overdriven. Am I on the right track or should I look at a differnt circuit? This also happens without the rgb hooked up so its not a color issue and is on my testing tube which is good.

did a full capkit just to cover the bases, no luck... took a reading on the neckborad of the colors and they are all low, 15vdc on each which is causing all three colors to blast. Will have to see whats common about all 3 colors to make this happen, I think i am close. any input would be helpful.
 
trace was broken on pin 7 of the flyback connecting to D503. visually the trace looks fine but when I checked with a meter it was open. up and working.
