    Need HP LCD Connectors, Please Help

    Hello everybody, this is my first message on these boards. I have a dilema and am hoping you guys can help me out. I have an old HP laptop with a nice 14" lcd that I'd like to wire into my car. The laptop base and lcd are attaced by a 50 pin connector (not all are used) that I just CANNOT seem to find. I've been looking nearly 2 years now. I'd just like to create an extension cord to go between the base and the LCD, with the prober connectors at each end.
    However, like I said, I've had no luck finding them yet. I was hoping that somebody here might know where they may be found. Any help would be more than appreciated. Here are the few specs I've found on this screen:

    Laptop Model #: Hewlett Packard N3478
    14" XGA active-matrix (TFT) display
    1024x768 32-Bit

    I've included a 6 pictures to make it much more easier.
    The Connector
    The Male End 1
    The Male End 2
    The Female End
    Male/Female Ends
    The LCD Itself

    This will be posted in both the LCD and Newbie Forum. If there's a problem with that, MODS, feel free to move/bin it. My appologies.
    Contact info is in my members profile. Feel free to msg me. Questions are welcome.

    Thanks in Advance Everybody!

    FYI... do not cross post in the future.

    now, extending LCD cables is a risky business. they tend to be very low power, and as such, extending them you run the risk of adding a lot of interference. im not trying to de-bunk your idea, just pointing out some potential problems.

    the connectors you show appear to be 25x2 (@.100 spacing) but i cant really tell just by the pictures. have you looked on digi-key ( www.digikey.com )?

    anyway, since they are actually wires connecting the screen to the base, you could always cut and solder in extensions to the wires. that would probaby be the best way, as you could maintain the original end hardware, and still get an extended cable.

    best of luck.

    Thanks for the responce. Sorry about cross posting, my word it wont happen again. I too was worried about attenuation of the wires. If I cut the wires and extend them, and it doesnt work, I've basically ruined a good laptop, thats why I wanted to make an extension. If something does go wrong, I'll still be able to use the laptop. I haven't looked on digi-key but will do so in a few minutes. Thanks again.

    I just finished looking through the digi-key catalogue and there are SO many connectors that look close but I really have no way of telling without holding them in my hands. Anybody else care to take a crack at what type of connector it is??

    Extending a Laptop LCD cable

    I have just finished building an extended cable to remote mount a HP Omnibook 7100 LCD in My Jeep Liberty. I disassembled the LCD and removed the entire existing cable assembly from the back of the screen. I removed the flexible fabric shield from the cable for later use. The fabric is metallic and solderable. I think it may be silver!
    That gave me about 8" of cable from the motherboard plug to the LCD data plug and the inverter plug on the screen.
    After much reading about the "low voltage differential signal" system I figured I needed a shielded twisted pair cable. I took a small gamble and cut the end off a 3ft SCSI cable. It had enough twisted pair conductors.
    I cut original cable halfway and spliced (soldered and heatshrinked) the SCSI cable between the two ends. It was a ###***!! of a job to do and I was very careful to list all the colors I was matching prior to commencing the work.
    On completion I checked each conductor with a multimeter and then used the fabric shield material to shield the exposed conductors.
    Finally I connected the LCD to the computer and it worked perfectly with no loss of quality and no screen noise.
    Now I just have to fit everything to the car!
