Found the service manual. There are no notes about tripler/flyback failure. The reference line shows a 7 watt resistor going to brightness limiting from the tripler. This must supply a voltage to the video circuit to allow it to control brighness. The only note is about stretched vertical. A zener in the power supply fails and causes that.
