Armando, You can also remove the collector of the horz. output and then 
measure the B+ there and see if you have about 130v if so either the fly is 
bad or it could also be a bad yoke. You can remove the yoke and look inside 
you might see a greenish look on the windings which might be a short.

Good luck
