Pin 2 no longer triggering motion on 6 zone board

Hello, I had my Konnected 6 zone board installed about a year and a half ago and it worked flawlessly until recently.

My Living room motion sensor is attached to Pin 2 and this no longer work. The motion sensor still flash the red light but no movements are detected in home assistant.

I tried to replace the motion sensore with a brand new one but this did not make a difference.

I now tried to swap my living room and hallway sensors. The hallway sensor is normally on pin1. But to test, I added hallway to pin 2 and living room to pin 1 and lv works and hallway doesn’t.
This makes me think that there is something wrong with pin2.

Edit: after some further troubleshooting with chatgpt. The fault seem to be the resistor for Pin 2.
The voltage is the same for all pins but the amps is 15 when other pins are 50. I also tried the ohm of the resistor and it reads 1, when other reads much much lower values.
According to chatgpt the resistor is fried?

I’m not expert and do not want to toy with the board and break it more. and soldering is not an option for this as too small for my skill level.

What can I do?
