Flyback Transformer Shot?

Jun 25, 2009 2 Replies

Hi,



I'm trying to get an old Loewe Colour TV going. I replaced a blown fuse, but now I get a corona discharge at the top of the flyback transformer where it shouldn't be.



Any definitive opinions as to the cause? Do I just need a new flyback transformer, or could it be more serious?



Regards, Tressie.


Gotta ask yourself why did the flyback short out? Maybe it was just a shorted winding, or maybe whatever was hooked to the transformer is bad and caused it to burn out... like the picture tube. Still it might be worth it to just replace it and hope for the best. If it is the tube that's gone, do you 'really' want to fix it?

Okay, how about if I go dumpster diving for a new transformer. What are my chances of finding a compatible replacement in a similarly sized, yet not necessarily the same model of TV? Are flyback transformers all different, or are there a few models which are common to different sets?

Regards, Tressie.
