I am trying to figure out why my GPS antena is not coming to life. It used to work so I think that the wires are good.
I did ton of reading here, and looks like everything is configured like it should be.
Do I have any advanced option to troubleshoot?

What does the GPS FIX STATUS Page say? See picture below.
If you want a temporary work around, it looks like you have some kind of Garmin GPS installed per the other GPS antenna. If you have it connected through the ARINC429 module, change serial port 5 to POS 2, and be sure the Garmin GPS is set to GPS 1 in the ARINC429 setup, then your Garmin will have a high priority than POS 2 and will become your SkyView position source.
Now, if it worked before, and you did no wiring changes, check all you connections from the screen to the 2020 receiver. Check the power, ground and serial lines. If there is any slop (flexing) in the wiring going into the receiver, and the wiring moves, through the flexing of the wires, you might have broken one, and it will fail.
