It's hard to see, but is the black wire tied to ground under the black screw head? Is that gold jack the back side of an RCA jack? It looks like there isn't a wire in the center pin of that gold jack. I would bet the loose white wire was not properly soldered to the center of that jack.

It looks like a soldered connection, so you need to solder it. It must have been a cold solder joint and the solder didn't bind to the wire. You will need a soldering iron and some flux or flux core solder. If you don't know how to solder, find someone who does or take it to any electronics repair shop. Just to re-solder a wire should only cost $5. Or they may even do it for free.
