It all started when I moved (yanked) the unit without knowing the jacks had cables still plugged in. Lost sound in one. Eventually (past year or two) I took it upon myself to remove both jacks and attach new. Nothing until I attached wire that I show in photo mockup. Now I have one with audio the other nothing.
These are not photos of my board just using to show the problem.
Any ideas for a basic novice with a modicum of soldering skills to try or bite the bullet and pay someone. I would really like to learn though.
