I picked up a free craigslist Fisher 25 inch TV the other day knowing that the TV didn't work.
The TV won't turn on and I have traced it down to a shorted 2SD1428 horizontal output transistor, so my question is does this have a bad flyback transformer? I have a good spare 2SD1428 in all my parts, but I don't want to put it in and have it short again.
I have had excellent sucess in removing the STK audio amplifier circuits in many old junk projection TV's and using them as stand alone stereo amplifiers. This one also has an STK amp circuit which I might just salvage instead of buying a new flyback transformer.
I am more of the audio afficiendo and am not really comfortable with TV repair.
Any TV guys know about flyback transformer failure?
Thanks.
