Hello everyone, this is a 2013 Day One 1537 Controller I got from a lot, which is working just fine, except for the anaolg sticks that wont respond to any input. The weird thing is that as soon as I press any button (no matter which one) the sticks would immediatly point at the maximum right bottom, and permanently stay there until I disconnect it. If no button is pressed, the analogs would just not respond to any movement. They obviously are known good ones and previously tested in another controller.
Visually inspecting the board, I could clearly see that the MCU was slightly cracked exactly in front of the U1 chip, and that caused 3 traces to break, precisely the ground one and the other 2 under it.

Changing the Power board would not affect this issue.
Is there any particular component I should check? I've checked almost every capacitor and resistor and I didn't find anything shorted so far. Thanks in advance
