... no components ... so the problem is a poor connection someplace. Try spraying liberally with electronic contact cleaner. Also jiggle each wire where it fastens down ... they usually tend to come loose or break towards the end, where they get bent a lot. If you are careful, bend the copper spring contacts a little so that firm contact is restored.
... Try the contact cleaner first, a small brush might help. Maybe the copper contacts have oxidized due to humidity or other moisture.
