Quoted from Tomshine:The pin in question is 33 as seen in this pic, what Iām not sure on is where this pin connects too - SWJ2 D1?
This pin is connected to the powerdriverboard "line level detect" - LOW. It is not used in the software
Quoted from Tomshine:Could you explain or reference what this pin relates to then? Should I look to repair?
It is the circuit that monitors the +18V , well known of the flickering LEDs 2+3.
As you can see in the picture, in the latter boards not even stuffed on the PCB.
It is not needed to repair.
edit:
and also visible in the picture, the 2 unused jumpers next to R197 are directly connected to pin 32 and 33 of J113
