All those are GI, and are stung together in a single series. There will be yellow wires going to all of the sockets - and ONE socket will have a colored and colored/white wires ALSO leading to it. Likely one of these wires came loose.
Find it, re-solder it on (with the game off, of course..) and you're good to go.
Won't be a fuse, since there are other lights on that GI string (up above pop bumpers, around gumball machine, inlane divider) - if THOSE are out as well, then check fuse.
