    I assume by "hot" you mean 110 volts above ground voltage and the lamps are 110 volt.

    The Black will be "hot" when the lamp is switched on. The White should close to the ground voltage at all times.

    Therefore I would suggest that the white wire has become disconnected some where.

    What you say is basically correct but voltage in the US is 120V not 110V.
