Jerry, What type of equipment did you use to ring the bad flyback with?

Sony KP-43T75 RA3A HOT keeps shorting. Unsolder-ed collector getting 135V. I have the training manual for the KP43T75. Any history of bad flybacks in this one as a common failure? Flyback rings good at 27 but when we did a dynamic test we only got 500V I believe this is low. Question if diodes in flyback where open or shorted would it still ring good? Thanks for any help.
