Xbox 1914 controller analogs and triggers wont work

[Halotestin92]

Hello, the triggers and analogs in one of my controllers have stopped working. It looks like after turning on the controller the triggers do not respond at all and both analogs after a while after turning on go completely to the lower right corner. I have already replaced the board with analogs and it is the culprit but I wonder what is wrong with it and whether it can be fixed. best regards
