      Did more changes, lifted the pins on 315-5313 to isolate RGBS. Still not working.

      Please help

        I am doing the same thing with the exact same japanese mega drive board that has the CXA1145 in reverse.

        I can’t get the sync to work! There is no video also if I use a composite video cable.

        Added a resistor from blue pin 29 to cysnch. I also removed a capacitor on the other end of the resistor.
