Controller Repair

My Gen 2 controller just stopped working. When I plug it in, the 1st light blinks once but nothing after that. Have confirmed that the wall adapter is not the issue by swapping with some of my other Rachio controllers. I saw a YT video from Australia where a guy replaced a bad capacitor on the board and saved the controller. Have already replaced the bad unit with a Gen 3 but would love to repair the Gen 2 if possible. Does anyone know of a repair facility that does this type of work?
