    Samsung UN55D6400 Service Manual

    Just picked up a Samsung UN55D6400 today.

    Trying to find a Service Man. or Scheme for it before I get into though.
    Haven't had much luck.

    Apparently, the UN40/46/55/60D6400 is hard to come by.

    Anyone have or know where I can find one ???

    Thanks

    Still looking for a Service Manual or schematic though, if anyone can help.

      I've got a un55d6000sf with a broken screen that I was planning to strip for parts.
      If any of the boards are the same let me know and we can work something out.
      The set turned on and displayed a menu, etc. so all the boards appear to work.

        I'll get into a little later today and see where it goes.

            In a transistor circuit protected by a fuse, the transistor will always blow to protect the fuse.

              Definitely helps, Thank You.

              Will certainly help with test points (and tp locations).

              If I could find a full scheme on the Main Board now - I'd be golden.


              Thanks again

              I appreciate all your help.
