> Good morning all.
> 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?
