the speedo is mechanical so it is not tied into the electrical system at all (well,really only the lights that illuminate it).It is cable driven from transmission to the cluster(gauge).
banging on the dash,to me,indicates a loose connection so you will have to disassemble the dash to get at it,simple as that.
