Easy way. Check the screen voltage on the HOT, if its high its an overload(bad flyback, shorted rectifier, cap, damper). If its low the problem is lack of drive to the HOT.
This one test instantly tells you if the issues is before or after the tube.
Ohh, btw...there is no 20xc36. I beleive there is a 20x1c36 and 1c38. i would look it up and tell you the pin number and voltage of the screen if i knew the chassis.
