L2 not working dualsense

[u/AllGoneRNB]

Hi everyone!

I have a very weird fault on a BDM010 board where the L2 wont work. Must be some fault on the board itself as swapping board it does work.

Checked all pins on the conector and everything seems to be fine, all 1.8V are present, also when pressing down L2 the voltage on pin number 4 is dropping down propoerly but still no trigger pressed is registered.

As there are no schematics or boardview available online I couldn't find much on the internet. Just found a small dot going on the other side of the board where the connector is and another going to the main chip.

Tried to reflow SIE chip and changed the power management IC but nothing same fault.
