The PCB is the circuit board, a shortened term for Printed Circuit Board. As
for the jack, it should be a separate part that is attached to the PCB. it
may or may not be enclosed in plastic. Under where the jack is located, you
sill see two or three silver colored pads that correspond to the legs of the
jack, check these for secure attachment, also check to ensure the traces (if
its a green coated board, the lighter of the green colors) are not broken.
if anything is amiss, you can 1) repair the item yourself, or 2) take it to
a friend or shop who knows how to repair electronic equipment. in the case
of 1 above, you would need a light duty pencil type soldering iron of about
20-30 watts. if any traces are broken, you can scrape the coating off with a
sharp knife until you expose the copper. Then bridge the break with small
gauge wire, soldered on both sides of the break. You problem is more likely
to be at the pads for the jack though, and simply reheating them with a
soldering iron so that the connection is repaired should solve your problem.
