On the board shown in the last image you posted there is corrosion on the 9 wire links, the connectors CB101 and CB10? and the component with 103Z on it ( I can't even make out the board designation for it because the corrosion is that bad but it should be a 10nF capacitor).
What is the underside of the board like?
You need to remove the board and gently clean off all the corrosion using Isopropyl Alcohol 99%+ and a Q-Tip. Don’t get the board too wet doing this as it could lift the traces off the board

When you've done that inspect the board for any damage to the copper traces that the components connect to and repair them and then clean up the links and connector and you may have to possibly resolder them to the board to ensure that there is a good electrical connection again

Hi @halorin
Did it get wet?
