R1 Dualsense model BDM-010 is activating alone
« 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.

Remove the circled Cap and retest. If it's still pressed after that, then it's either a short on that R1 line, and it's on an internal layer, or the MCU has an issue. A good cleaning that gets under the BGA chip or a reflow of it might resolve it.

Unfortunately it didn't work, I removed the circled Cap and blew hot air across the entire board but the problem continues.  :sadno:

How does it act with both of the Trigger modules plugged in? With the board like that, there are 4 Analog lines floating, and they can cause all manner of weird issues.
