If there's no short, measure the voltage on that transistor from collector to emitter - it should be over 100VDC. If that's missing, you work back toward the regulator. If that voltage is there, we work on the horizontal drive.
Is there a schematic on-line?

Do I need to leave the board in to do this or can I take it out?
