Pixhawk cube (black)

Hello Team!!!
I am using black cube on building a VTOL, but I encountered some issues with some ports on the pixhwak board, the power module Power 2 doesn’t work (I can’t use the port to either power the cube or monitor the voltage on the herelink), second, the main output 8, doesn’t out the signal. My questions are, what can I do to repair the ports, or Who to contact for help. Thank you!

Did you connect with the manufacturer for this port issue?

yeah, but no feedback
