On your first photo it appears that one end of that ribbon cable goes into a ZIF socket on the circuit board and we see that the other end is apparently broken off. It looks to me like it goes to the traveling mechanism that holds the read head, which would make sense that it broke off since it flexes probably multiple times every time a disk gets played.
I'm wondering about how that end is connected and to where exactly. If I had to guess, I'd say it goes to the spot I've circled in your second photo; does that seem right? Is the rest of the flex cable soldered on there, or is that my aged eyes playing tricks on me?
