I have a set of very old computer speakers that works fine except for one problem. One of the wires connecting to the volume control dial is loose, so that if the wire is jostled or flexed, the speakers lose sound. I'd have to re-jostle or flex the cable into another position before the sound can be heard again.
The image below shows the problematic cord:
I circled a region in pink. The sound disappears or re-appears depending on how the pink region is flexed or jostled.
I want to know how I can repair this problematic cord? Should I strip away the black plastic casing of just the pink region, then try to solder the metal wires that have been damaged, then tape things back up? Or are there some other off-the-shelf components I can consider?
