摘要： A display apparatus and a power supplying method are provided. The display apparatus includes a signal receiver which receives a video signal; a signal processor which processes the video signal; a display unit which displays an image based on a video signal processed by the signal processor; and a power supply which converts an alternating current (AC) voltage into a direct current (DC) voltage and supplies an operation voltage to the display unit, the power supply including: a power factor correction (PFC) unit which adjusts the DC voltage and corrects a power factor of the power supply; a detector which detects a plurality of voltages in the power supply and outputs a common detection signal indicating whether at least one of the plurality of voltages is abnormal; and a controller which receives the common detection signal, and controls the PFC unit based on the common detection signal.
