Take the controller apart and make sure the Magnets are still on the Triggers.
You really need an Oscilloscope to see what is going on with the Hall Sensors there.
Make sure R39 and R42 are 100ohms.
Make sure C36 and C38 are not shorted.
U10 and U11
1 - VCC, 125Hz, 3.3v p/p
2 - OUT, 125Hz, ~1.5v not pulled, ~0.3v pulled
3 - GND
If U10 and U9 check bad, make sure U9 is working.
U9
1 - 125Hz Out, to Hall VCC
2 - GND
3 - 125Hz In, from MCU
4 - 3.3v
