  • Short Lilliput cable?

    I'm putting together an indash pc and the Lilliput's cable it's way to long.
    There is a way to shorten it?
    how it's connected the USB in the cable? it can be separated?

    its a bit tricky because USB data lines goes on pin 8 TMDS Data0 Shield and pin 17 DDC/CEC Ground - they are grounded in a normal HDMI cable

    easiest way is to buy a cheap short USB and HDMI cable on ebay, then cut the plastic on monitor side from HDMI cable:
    - disconnect the ground wires from pin 8 and 17
    - connect these wires to other ground point
    - cut the connector on one side of USB cable and connect black to a ground point, leave red unconnected
    - connect USB's white and green to pin 8 and 17 (test it and swap if doesnt work, You cant make trouble with swapped lines)
    - cover the connector with hot glue gun to protect it from short circuit

    here is an example from my other project, ignore the connectet circuit, just for HDMI mod:

    "case": Skoda Superb Elegance 1.8T
    Asrock G41MH-GE, E2180 2GHz dualcore, 1024MB DDR2/800, Samsung F1 750GB/7200RPM/32MB, M4-ATX, Lilliput FA1011 HDMI touchscreen, ASUS Xonar DG PCI, homemade Quectel L10 USB GPS

      What model Lilliput do you have?

        Koszonom Peter a segitseget.
        thanks for the fast reply, but I should have mentioned that I will be using the VGA cable.
        I have the 669HB.

            it's ok to just cut the cable and resolder all the wires?

              anybody found that monitor connector somewhere?
              I have researched online but it looks like nobody found it yet.
              to me it looks like a D terminal connector with 14 pins, but I'm not sure if it's D1, D2, D3 or D4?
              it looks like they use it in Japan for HD.
              if I could get this connector, I could make my own cable.

                This is perfect for what I am trying to accomplish. I have tried to connect my 669 HB model through the VGA USB touchscreen cable, but the only time that actually works is when I use VGA as the actual output, I can't use HDMI as video output and the VGA USB for the touchscreen.

                I am trying to attempt to solder this and it is a difficult task. I was wondering if you were able to figure out where the white and green wires are connected to exactly(8 or 17), you said to just switch them if unsure, I only have one shot at this so I was wondering if you could pass anymore knowledge on. The other question I had is what ground pin did you use? Did you use the main ground pin that is attached to the housing of the HDMI cable, or use a specific pin? Any info or diagrams I would truly appreciate. Thanks for your input and help!

                  now i have changed this cable to a simple untouched, 90-degree cable because my new G41 motherboard's integrated X4500 drives it very well via HDMI without any up/downscaling, its picture is perfect. i made some other modification on the PCB inside the monitor for USB touchscreen: 2 PCB-wire goes to the VGA and HDMI connector from the controller area - there is 2 0-Ohm SMD resistor on them - i have desoldered these resistors and wired the touchscreen to an external USB cable. so the controller and the HDMI/VGA connectors are separated now...

                  regarding to the 8/17 pins: i will try to find my notes about it, might be documented somewhere... but gives no any error if they are swapped - only not detected by windows, or gives "unknown device" message...
