Matrix 1 controller D-pad Left, up, and analog sticks button not working

[jesusma]

Hello amigos.

I have made a lot of investigation before this post. I have a matrix 1 wireless controller. The following buttons do not work: D-down D-up and both click button on sticks. All these buttons are from D16 and D18. According to this diagram.





Continuity is confirmed in all traces to the MCU and the resistors and caps that are in the diagram. I swap the D16 and D18 but still not working.

Any other Idea will be appreciated thank you for your time.

Check the Orange/White trace that goes from IC1p40 to D16p3 and D18p3, suspect an open there. If that's good then IC1 is suspect.
