    Hi there - I've taken a week off from work to go home for Thanksgiving
    and my mother has requested I fix her TV to earn my keep. She has a
    fairly spendy LCD that is many years out of warranty. It has an
    external DC brick power supply that connects to the back of the LCD
    through a DIN connector. I believe the connector is proprietary - 3
    pins, one thinner than the other two and recessed back a little, and
    the other two are big and thick. I've never seen a DIN connector like
    it. Anyways - it seems the cable got repeatedly yanked on and now it
    only works when you press against the DIN connector in a specific way.
    I'm probably going to ghetto-rig a zip tie to hold it in that position
    and call it a day - but I was wondering - would anybody have any
    suggestions as to how to fix it?

    I pulled the PCB and there were no signs of damage on the PCB. No
    fractures in the solder joints for the through hole right angle DIN
    connector. No loose pins. No visible damage on either connector.
    Nothing.

    It is a Toshiba 20HLV85, if it matters.

    Thanks!

    -Michael
