Have you checked all the cathode voltages (Rg, Bg & Gg)? If not check it. If the Gg voltage is found much less than the other two cathode voltages, the fault might be to the green video output transistor, or its collector load resistor. In service mode too, there are adjustments. All of it cannot be stated here. anyway, check the above stated voltages first. CRT cathodes are negative biased, that is, if the voltage at the cathode become low, the intensity of color to that cathode too. If you wish to get more details, come over by comment.
