    Asus G750JZ R2.0 just need one resistor value

    No picture on LCD panel, resistor between DDC power pin (pin 22 on display conn) and +3VS is open circuit. Probably caused by bad display cable, now replaced.

    Value of resistor? It might be just 0 ohm, but just wanted to make sure.

    try this schematics if its the same. ..https://www.badcaps.net/forum/attach...9&d=1507792334

      No, it's not the same. DDC power comes straight from +3VS on that board, no resistor in between.

          Thank you, Sir!

          It was indeed zero ohms, that's what I used already. After replacing, got picture with lots of static.

          U6201 eDP to LVDS bridge chip was also damaged, took that from a donor board and after replacement picture was OK.

          Previous shop also damaged display and HDD connectors, need to swap those too.

            ASUS TUF B450-PLUS II motherboard schematics, or does this 60B SMD resistor even matter?
            by schematic_jack
            I think it would be dumb to toss a "modern" motherboard just because a resistor got scraped off, so here I am. I am hoping to find the right schematic so I can see if the motherboard can live without 1 of 3 60B SMDs in series likely scratched off by the backplate of a PCI-E card install or removal. It could be related to a functionality that is not needed or critical, or it could fry anything I plug into it and power on. If I could find a replacement, I could likely pop in on the board, but if I don't need to, then screw it, I don't mind leaving something dark that doesn't matter....

            Need help identifying resistor on Asus FA507RC DA0NJNMBAD0 schematic
            by dutchgaucho
            Hi colleagues,

            Looking for a schematic DA0NJNMBAD0 or the MP2845A 6-phase PWM controller.

            Working here on a DA0NJNMBAD0 rev D motherboard (Asus FA507RC) with liquid damage. Board has some tiny corrosion around the MP2845A controller and one resistor is missing. I need to know the value of the resistor, but no schematics are available. Not even for the MP chip or anything similar (this is a 6 phase PWM controller).

            On one side of the pad 20V is present. The other side connects to a cap and to pin 16 of the MP2845A. Resistor seems too small for VCC...
