    Re: Westinghouse SK-32H240S Sob story with a Darfon board

    No ideas?

    Trying to understand what's going on with this one. Starts up and fires all the ccfl's without issue. Bad caps replaced.

    Trying to understand the jumbo capacitor test. It's got over 370vdc sitting on one terminal. Just need some direction. Only test I could do with the mosfet's is to compare each leg 1-2 1-3 2-1 etc... Checking to ensure each one does the exact same thing and behaves the same. Not the best test in the world, but the closest one I can think of. (considering the ccfl's are all firing at first? wouldn't a dead mosfet cause the lights NOT to lite up? or am I missing something?)

      We are scrapping it for parts. I pulled the main screen off in one piece. Darfon board and the cpu/guts/tuner/all that jazz pulled. We'll list them for parts value (the main cpu works great, the darfon can be stripped for anything needed)

      Much as I do not like it. Beating a dead horse at this stage of the game makes no sense.

      (Plus no one here ever seemed to make it to completion on one of these repairs. I keep seeing hints....direction to follow..and then people fall off the planet.)

        The one I fixed which is similar setup with 3 transformers, I just had to replace just one bad transformer.
