A video apparatus having a display module and a method of controlling the same are provided, whereby an electric field strength or automatic gain control (AGC) signal is recognized from a received broadcast signal and a power supply mode of the display module is controlled according to a level of the recognized AGC signal, to prevent an overheating of the display module without using an additional device. The video apparatus includes a display module for displaying a broadcast signal received via a broadcast channel, the display module being selectively driven according to one of a plurality of power supply modes; and a controller for controllably setting the power supply mode of the display module according to the strength of an electric field of the received broadcast signal, the controller maintaining the set power supply mode if the electric field strength lies between lower and upper thresholds defining a threshold region.
