Hello! Good morning/afternoon/night
I'm trying to fix (learning how to fix) a jdm-055 that is stuck thinking that it's charging. Here's the puzzle:
Symptom set 1 - The board connects via usb to my pc and works almost perfectly fine. DS4Windows says that its battery is at 45+ (which means that it's at 45% and "charging"). But when I connect it via bluetooth, it also says "45+". When I press the reset button and release it, it doesn't turn off but instead it starts showing the orange light thinking that it's "charging".
Symptom set 2: I said above that while connected via usb it works almost perfectly fine, but the issue there comes when I disconnect it from the usb cable. Even when the bluetooth of my pc is tuned off, when I disconnect the usb cable it keeps showing the blue light, thinking that it's still "connected" via usb. But when I try the same via bluetooth (connect then disconnect), it doesn't show the blue light; it rather goes back to the orange light.
Symptom set 3: when I try a usb ampere meter, it shows no charging activity.
So the board clearly has a usb issue, but I know it's not the child board because even when I connect the controller via bluetooth to my pc without the child board, DS4Windows still says that it's charging. So the problem is on the board, but I don't know if it's the charge ic or the components around it that I could test if I knew (I'm learning).
Please help me if you know. I'll appreciate it <3
