Loss of vertical sweep - check the 'GF7 voltages, look for any broken wires - the wires on the wirewrap terminals break easily. Check that the yoke wires are okay, not pulled from the plug or the yoke.
Possibilities:
Vert Osc quit
XXGF7 tube quit
B+ bad to 'GF7
broken wires - terminals or yoke
bad ground to vertical area (eyelet solder grounds on board in Vertical osc/output area)
open resistor in the 'GF7 area
.....and yes I've seen service switches fail, but check okay in circuit.
