    Filter Cap R&R _ LG42 PDP 42x3

    Hi, does anyone have the parts list for this set?
    So far, I've only found a the Service Manual without the Parts List.

    I need to replace the Iron Inductor, (Filter Capacitor?) labeled as
    L1050 H A , 3/8" dia, x 3/4" long.

    at location L507 of the power supply board 782-ph42d8-2000
    I can't find any reference on the web.

    I'll also check the nearby components for failure as well.

    Any help would be appreciated.
    thanks, Sixstrung

    The letter "L" is the indicator for an inductor (a coil) not a capacitor. Capacitors are labled as "C" - and whatever number after that. Inductors usually (99 times out of 100) do not go bad. I have seen bad solder joints on a few but most likely you may have the indication of the component you really want to change mixed up. Take a picture of the board in question and the area. Post it here using "Manage Attachments" and you'll be pointed in the right direction for the fix.

      Thanks for the reply DG
      I removed the inductor because its sheath overheated and split wide open, either on its own or caused by the nearly touching, two 25v, 3300uF caps, or the F20JC10 transistor.... none of which show any deformation, leakage, etc.
      I can not find, or identify a replacement for the inductor.
      Can you suggest a direction to locate a replacement inductor?
      I'll chase the circuit for failures.
      thanks.

        I really couldnt tell you how to replace the inductor other than to find a service manual on the device and get a direct replacement from the original manufacturer.

          It may not be necessary. If the inductor is a heavy gauge wire wound around a ferrite core, just put a piece of heat shrink tubing over it.

          For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

          Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

            Thanks Bill, you are correct.... though I believe the heavy gage copper wire has a clear protective sheath on it prior to being wound on the ferite core.
            Though I can't tell, I suspect that the wire's clear sheath melted somewhat when the inductor's outer wrapping melted.
