    I am trying to figure out why my firewire port doesn't work anymore on
    my camcorder.

    I am wondering just how the inside of it works - where the pins meet,
    but I can't seem to find any information or images of what it looks
    like. Does anyone know? I have taken apart the cable, but not the
    camcorder (the camcorder has bent pins). I am hoping I can figure out
    where the pins are bent and how the cable and the input on the
    camcorder work together. Any help or images would be great.

    Thanks

    Thanks for that, but I need to know if I am going to do any damage to
    the camcorder if I cross pins and the like, that is why I was hoping
    to see a picture of the inside of the DV camera firewire port.
     
  4. This is a problem you should refer to a qualified tech. If you're
    embarrassed because you did something "dumb" to bend the pins -- well, it
    happens to all of us.

    Well that's the best I could do. Firewire is actually a serial data port
    like an RS-232 port. Don't know what damage you could have caused to a 4
    pin port considering that they are twisted pair data and clock lines with
    no power supply IIRC. Best bet is to get the device to a qualified tech
    and let them determine if the pins have been bent or crossed and if so, if
    they can be straightened out. Chances are low that any electronic damage
    was done to the device.

    Thanks for that. I would like to get them straighten, if possible,
    the only problem is that when I phoned a tech place, they want to
    change the board rather than try to straighten the pins - that means
    at least $200.00. I was hoping that if I could extend the pins of the
    cable long enough, I might manage to touch the bent pins inside the
    camera, but I worried about frying the whole camcorder by doing
    this...maybe?

    Go to http://www.interfacebus.com/Design_Connector_Firewire.html#e
    and link to the connector manufacturers' websites to look for specs
    (yours is likely a 4-pin PCB mount). Or buy a connector from Mouser
    or Digikey so you can tell what a normal one looks like.

    Looking at the DV jack on my Sony Mini DV I really don't think it's
    something that can be done. I don't even see how the metal contacts were
    bent seeing they are well slotted in the plastic center piece. It's
    understandable that the tech wants to replace rather than repair. If you
    want to try it, have a big old magnifying glass, a lot of light and some
    micro tools. You can remove the camcorder battery but really there's no
    voltages there to fry, just clock and serial data.

    Looking at the DV jack on my Sony Mini DV I really don't think it's
    I don't really have the tiny tool, but I do have the light magnifier.
    I was thinking that maybe they are bent and maybe broken, so I was
    trying to connect them somehow. I can work fine without the battery,
    but at some point I have to test it, and that is what I am worried
    about - testing it on my computer (plugged in) and camcordering
    (battery) and finding it fries the whole board because the 4 pins of
    the cable hit the 4 pins of the camcorder in the wrong way, or hit the
    wrong pins-
