Epiphone V 7 pickup problems...halp?!?

[Vairocarnal]

The neck pickup works but the bridge (Tone Zone) makes no sound whatsoever. It's all stock besides the bridge P.U. Has anyone had this problem before? Is anyone hoarding any schematics/diagrams that might aid with this? Thanks for the time and any possible advice, -V

Open up the electronics cavity and see if anything came loose, namely around the selector switch. Even if you don't see something blatantly wrong, redo all the solder joints, as a cold solder could be a possibility.

Though, to your knowledge, did the bridge pickup ever function properly?
