Title: R1 Dualsense model BDM-010 is activating alone
Post by: blueloogann on September 27, 2023, 04:29:51 PM: Hello guys, how are you? Guys, I'm here to ask for your help, my control is having this problem, it's activating R1 on its own, as if it's being pressed, I've already disassembled it all, so I left the board connected to the USB Type-C cable and the button R1 remains pressed. Does anyone here know what's happening and how to fix it? I've already cleaned the entire board with isopropyl alcohol and looked under the microscope and didn't find anything different. Thanks.
