Tough call, but I'd suspect a bad solder joint on the board around the horizontal output first. Second I would suspect an open winding on the flyback, and third a bad connection to/open winding on the deflection yoke.
Try letting it cool down for a 1/2 hour and then see if it comes back to life. If not, wiggle the 6DQ6 horizontal output tube in its socket lightly while it's on to see if high voltage comes back. If not, check the plate of the horizontal output and see if it's glowing cherry red... if so, this means the horizontal oscillator is dead. Otherwise you'll have to check the resistance and continuity through the flyback and yoke.
Could also be a simple power supply issue, without a print in front of me I can't help to pinpoint that though.
