摘要： A display apparatus, a power supply apparatus and a power supply method are provided. The display apparatus display apparatus includes: a signal receiving unit which receives an image signal; a signal processing unit which processes the image signal; a display unit which displays an image based on the image signal processed by the signal processing unit; and a power supply unit which receives AC power and supplies operation power to the display unit. The power supply unit includes a discharging circuit part which includes a discharging element which discharges the power supply unit to remove a residual voltage from the power supply unit when the AC power is suspended, the discharging circuit part preventing the discharging element from consuming power when the AC power is input. It is possible to minimize wasteful power consumption caused by a discharging element provided to guarantee user's safety against a residual voltage.
