Telephone Headsets: Identifying Plug Cable Colors, Soldering & Resin Issues - Red, Blue, Green

Headset. They stopped playing, but when I move the plug, only one earphone plays. After dismantling the plug, everything was covered with some plastic / resin, it is difficult to see where which color is soldered. Certainly red was the first, in the second there were several (gold and probably golden-green for sure, because you can see a piece of green), in the third - blue, in the fourth - green.
Could two gold and the third green-gold one be soldered in the second pin? In the photo, when it gets bigger, you can see two gold stumps soldered but I don't know.

2 is the golden-green one in the picture at the bottom.

Yes, this cable should be there, everything works.
