Display apparatus and method of controlling the same

A method of controlling a display apparatus, the display apparatus including a display, a content receiver, and a communication interface, the method comprising:

• storing, by a storage, setting values of factors related to respective operations of the content receiver, the communication interface, and the display;
• determining, by a controller, whether at least one of the content receiver, the communication interface, or the display are at a risk of operation error;
• when it is determined that there is risk of operation error of the at least one of the content receiver, the communication interface, or the display, determining, by the controller, whether risk of operation error is caused by a setting value while changing the setting value of a factor related to operation of the at least one of the content receiver, the communication interface, or the display;
• and
• when it is determined that there is risk of operation error caused due to the changed setting value, transmitting, by the controller, information about the factor and the operation error to a service apparatus through the communication interface,
• wherein the determining of whether the at least one of the content receiver, the communication interface, or the display are at risk of operation error comprises:
• determining a normal operation range of the factor that causes the at least one of the content receiver, the communication interface, or the display to operate normally while changing a value of the factor, and
• determining whether there is risk of operation error of the at least one of the content receiver, the communication interface, and the display by the setting value of the factor, based on the normal operation range of the factor and the setting value of the factor.
