Measure the voltage on the grid and screen grid of the horizontal output tube.
The grid will tell you if you're horizontal oscillator lives and the screen can give info on whether there's issues on the flyback side.

The entire horizontal system has to work for there to be HV. It's typically much faster to troubleshoot that system than it is to shotgun parts (though replacement of paper and lytic caps is probably wise).
