Pro Controller completely dead

Hello, this is my first time posting here. I got a pro controller for cheap some time ago that was broken. Turns out the controller is completely dead. No limits come on when trying to charge it neither when pressing buttons and the switch does not recognize it. The usb C port is fine so I’m sure the problem lies somewhere in the motherboard but I’m not that knowledgeable about resistors fuses and stuff so I don’t really know what to check. If someone has encountered this problem before please do help me fix it.
