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.

Anyway, thanks for the following up and getting your TV working again.

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.
