    Inductor check

    Hello again folks.
    I found an might-be-broken inductor in my Fox TV. I have 0 experience with inductors and don't know how to check it. It looks like its broken. When I placed it in my ESR meter it shows that it is an inductor (witch means it should be working) but the values measured don't match the one written on it. (or at least I don't know how to read them). Here are the pictures.

    Also, the resistance on it is varying very much until it gets close to zero when I check it with my multimeter.

        Looks like a custom inductor and who knows what's on the heatshrink. 60µH is possible, but I'd suspect less because there can't be that many windings with wire that thick.

        Why do you suspect it bad, inductors usually don't break unless physically broken (varnish melted or smashed)...

          The printing on that black shrink tube is for the shrink tubing not the value of the inductor.
          Low DCR of 0.3 Ohms is about right for inductor that size.
          Bad inductor usually goes open circuit or it shorted turn.
          May be you should post the problem of your TV including all the details, make and model, and pictures in the TV section to get help.
