Looks like your Battery holder might be in bad shape. Looks like the top contact is missing and the middle one has turned blue.

Your remade plug at CN2 Does not look correct, is there a red/white wire connected with the gray/white 12 volt wire? When comparing to pics online there is only 4 wires on that plug. Yours looks like it has 5. If so this could be some of the problem.
You may want to trace down where the red wire that is attached to the Gray wire goes because 12 volts was sent to the other end. Red wires are normally 5 volts. Maybe both reds that are on the CN2 plug.
If you don't have a manual it might pay to get one.
Look at page 110 of your manual. It tells you how the 5 volts is produced. You may have a bad voltage regulator. The regulator output is what R116 adjusts.
