Just unscrew, check, and reflow both ballthrough opto boards. If all is done well, you'll have no problems anymore. Just heat up and let the solder cool down, or add a tiny bit of fresh solder on the joints. If there are cracked traces, patch it up with some wires.
About the drop target, test it well using the coil test, I'm not sure what could cause that, but my guess is that solving the opto's first will be the main problem.
