    LX/MX motor stand plug wiring

    I have aquired a motor stand for my old LX but it has lost its plug.

    There are 4 wires; green, white, yellow and brown.

    Does anyone know to which pin each wire goes?

    Better still, if anyone has one could you possibly open the plug and post a picture?

    Thanks,

    Richard

    Re: LX/MX motor stand plug wiring

    Thanks Jaff

    I have a similar diagram in my LX5500 manual but it does not state which wire is which.  As a last resort I can strip the stand down so see which colour wire goes to the motor and which to the position transducer but I was hoping to avoid that if possible...

    Re: LX/MX motor stand plug wiring

    In case anyone else ever needs to know how to wire an MX motor stand I will document it here: -

    Pin 1 - Yellow

    Pin 3 - White

    Pins 2 & 4 - Green & Brown (pins 2 & 4 are connected on the board)

    The motor unit has far more to it than I expected; 2 pcbs with some kind of Intel chip, a crystal, about 6 small capacitors and lots of smd.

    Thank you for posting Smile I've seen this asked a number of times, and I don't think anybody ever provided the answer.

    The stand communicates with the TV using a serial data protocol, and so must have its own brains doing the actual work. That Intel chip must be the microcontroller then.
