Picade: down position now working



I have just purchased and install Picade on Retropie 4.0.2. But unfortunarely, the down position of the joystick does not work. I have tested the contact on the plug and the signal is going to the plug but nothing happend.
White led is flashing for all direction except down.
Can you help me?


Try double checking your connections between the joystick and the Picade PCB.
