A display apparatus including a main body, a power key provided in the main body to turn on/off power, a display to display an image thereon a signal input part to receive an image signal from an external device, a power supply to supply the power to circuits of the display apparatus, and a controller to detect the image signal input through the signal input part, to control the power supply and the display to convert the display apparatus into an automatic off mode in which the power supplied to the circuits is cut off when a normal image signal is not input, to maintain the automatic off mode if the image signal input is determined to be abnormal when the power key is input in the automatic off mode, and to display the image if the image signal input is determined to be normal. Thus the display apparatus and control method thereof prevents a user from being confused as to whether the power key is input to the display apparatus in a power off mode or in an automatic off mode, and is thereby simply operated by the user. |
