First does the chip have power, +12v on. Pin 13?
You must be getting horizontal so is there any 50hz sawtooth type signal on pins 11 or 10? I imagine the output you posted is pin 7 maybe? Have you checked that the deflection yoke isn’t open? If it’s ok, I would trace out the circuit and draw the schematic between the vertical yoke and the chip.
