Have a good mechanic look at it. A good mechanic who understands how that mechanism works should be able to look at it and determine what exactly isn't working and then can recommend what needs to be done to fix it. You need an expert diagnosis. As a mechanic I need three senses: touch, sight, and sound, to diagnose most things. You could take a series of photographs and give me the sight part. You may be able to film a movie to give me sight and sound. There's no substitute for touch though.
I know those shifters well, so if I had your bike in my stand I'm sure I'd have your diagnosis done in 30 seconds or so.
