Problem with PINDA sensor: lights up but the value change doesn't register when in contact with metal
Hey guys!
I've just finished assembling my new MK3S. It is my first 3D printer and I am super excited! However I've run into a problem I can't seem to solve 🙁
First off, during the first self-test nozzle crashed into the heatbed. I started reading, first solution was to adjust the PINDA sensor height. After tinkering with it for a good hour (and trying the test over and over) I was pretty sure it was in the right spot and the height wasn't the problem.
Read somewhere that maybe firmware has issues, updated to latest version from the website. Still the same issue.
So then I found the information that you can see the sensor value while checking with metal object (Support -> Sensor Information in the printer menu I think?) The light on the sensor reacts (off when in contact with metal objects), however the value never changes to 1. I wiggled the wires around gently as suggested somewhere, still nothing. Check connection etc in the electronics, seems to be exactly as on the pictures in manual.
I am running out of ideas what the issue could be. The sensor seems to be working, since the light changes? Could it be an issue with wires? My knowledge of electronics is almost none, so I don't know what else I can do.
I will really appreciate any help and suggestions.

The wiring is probably broken - there are four wires, Gnd, +5v, Out, and TC. Out is the one I'd question. Sometimes the break isn't intermittent. The only real test is to measure for voltage changes at the Einsy end of the cable. It should change from near 0v to near 5v as metal is applied to the PINDA tip, in conjunction with the LED state change.
