    useless stuff?

    I have a question what are those used for ? they clipped on cables. every time if they were on my way, I threw them in the garbage can right away. for me, they are useless stuff.

    It's a ferrite bead (EMI filter): https://en.wikipedia.org/wiki/Ferrite_bead

      Removing and throwing these away is equivalent of killing a kitten to any radio enthusiast.

      Eventually wifi and cellular service are included...

        I am fixing Coby 23 inch TV, they put that Emi protector on lvds cable. if it is so good how come they don't use right now (anymore)?

        This is entertainment equipment, not military or outer space equipment. Sometimes TVs came with metal casing. I threw in the garbage also and so far so good. No one complains

          Those thing are used so the device will pass FCC compliance tested and it depends on how well the device are made and put together as a whole.
