    Great job of tracking that down. Ironically, a bad fuse is mentioned in the 2 seconds to black guide, but I haven't mentioned it as a possible cause for a while now.
    Yes, I now see it... But it was really the CCFL test that helped me localize the faulty area.

    No, thank you! What I am wondering about now is what made the original fuse blow. Usually a fuse blows in unexpected or out-of-spec conditions, and obviously, I haven't fixed anything besides the fuse.

      I agree that fuses blow for a reason, but from what I have learned here with other cases, sometimes a fuse (like any other component) can just go bad on its own.

      If I had to guess it would be one of those ICs (Nikos) that may have blown a fuse. However, since your TV works, that implies all the components on the inverter board are working fine.
