    qn55qn85aaf schematic

    bn41-02855d Main board

    Feels like a long shot, but any one have the schematic for the main board?

    It seems to have a panel short that i cannot find. It feels like it is doing the VGH reboot thing that a few other series of samsung do, but i cannot conclusively locate the VHG pin/line.


    It will cycle/reboot forever unless i unplug the ribbon between the panel PCBs. If i plug that ribbon back in while running it will shutdown and begin the cycling with in a few seconds.

    Checked every passive on the panel for shorts and got nothing interesting. I can probably screw round with tape to find what pin is causing it, but ive had a lot of luck with samsungs in the past with increasing the value of the series resistor on the VGH line, and would like to give that a try.
Working...
