Try to identify the vertical deflection yoke. Test continuity(to be 10-15 ohms). Identify coupling capacitor and verify that it's not open. If all are ok, identify the actual deflection i.c. or circuit and confirm with 'scope that the drive signal from the jungle i.c is present and correct. If not present, confirm that the jungle i.c is getting all the necessary supplies from both the flyback transformer and from the power supply unit. If all are ok, replace the vertical i.c. Good luck!

If I had the schematic I could help you further.
