I am not sure if this is how the circuit is run but does it got in order of number? So R01 comes before R02 and then goes R03? Or is it just random? If they go in order, I was checking board to board in order, everything was the same up until R17. I pulled R20 as well and on the left side is open and right side is 6.82 k ohm.... not looking too good lol
