Try this:
1. Place a 47k resistor between pin 11(cathode) of the CRT and ground.
2. Connect a .05uf, 630v cap from pin 3 and 4(plate) of the 6K6 vertical output
to pin 11(cathode) of the CRT.
Basically you need a positive going vert deflection pulse at the CRT cathode in order to blank the picture during vertical retrace.
