>open and repair

easiest way to open it is to not open it
there's two more likely sources of potential intermittent breaks
that's where the wire gets bent the most: at the jack and at the speakers
so first thing is isolate the problem area
FIRMLY tape down the cable about 10 inches from both ends, and wiggle the extremities only
again, you need to tape it firmly so that the wiggling doesnt affect the middle of the cable
if that didnt do the trick, then try other short sections

if you must open it, see if you can find a seam, and use an acrylic scratcher and ruler.
