Test button jdm-030

Hi

I wanted to know how I can test the circle "O" button directly on the motherboard


I also changed the internal membrane but the circle button doesn't work so the problem is definitely on the motherboard



Thank you

You can short the pin that says "cir" to ground. Credits to RDC, I found the picture in one of his posts.





The "cir" connection also goes to this pin I scratched here





And then directly to the CPU
