    *panic* Extending LCD wiring... harness?

    A wiring harness is all I can think of to call it, using the 'converter' for my car stereo to fit my car without having to chop and splice. But anyway...

    I have a ruggedized laptop with a 12.1" touchscreen LCD (plenty big AND 16 bit color ;p). Basically I wanted to remove the LCD from the rest of the laptop and extend it slightly (a foot or two) so I could more easily mount it in my car. Though I had never done this before, I was comfortable enough to try it. Little did I realize that not ALL wires are solid core.

    I checked here to see whether other people had tried extending their LCD wiring, and enough had been successful that I proceeded on mine.

    Thinking I knew what I was doing, I very carefully took it apart (the part I'm good at) and proceeded to very carfully (still skilled at this point) to remove the mesh-like plastic covering that bundled the wires together. After discovering that they definitely WERE wires and not that zebra ribbon or whatever its called, I figured I'd be able to continue.

    But, as soon as I cut the first wire and realized that the inside of the wire was fibrous and not solid, I guess that's where I messed up. I tried splicing the wires back together with no extensions in place, but to no avail.

    Now, I'm at a point where I bought a second ruggedized laptop for parts (I needed a floppy and a new ethernet card anyway) so at this point, I now have an untouched wiring harness and one with a few wires cut, but (hopefully) not mixed up.

    I had also bought a Cold Heat soldering iron from Radio "Barn" but the tip is not narrow enough for delicate electronic work.

    I'm looking for suggestions on getting the first cannibalized mutilated one to work, or barring that, I'd like advice on how to go about putting up an ad to pay someone to do this for me. I don't feel like buying a third laptop.

    at your own risk take a cig lighter and burn the wire and see if the wires are able to be spliced after that. use an ohm meter to check for continuity.

    You mean apply heat to a stripped part of the firbous inner wire to see if it will burn the nonconducting fiber away while leaving the metal intact? Will try.

    I've done that a few times, just burn 1/2" off if you got that much space, then clean it by rubbing it gently, it'll never be really clean & it'll never solder 100%, but what you do is take a "good" wire that you'll use for the extention & wrap & twist it togeather, this won't solder like a regular wire though, the solder will sink & penitrate the "good" wire no problem, but the actual connection to the bad wire will be more mechanical, like a crimp kinda, enough wrapped & enough of a bead of solder can make a good connection, to be permanent you could epoxy the connection after to seal it & eliminate movement, that's the best your gonna do without having someone make you a harness, most times both ends can be gotten & assembled professionally, but the solder has worked many times
