Abstract
The present invention provides a TV power supply, which comprises a main power supply and a voltage conversion circuit electrically connected to the main power supply. The main power supply comprises a first output terminal for outputting a backlight driving voltage and a second output terminal for outputting a motherboard driving voltage. The voltage conversion circuit is configured to convert the backlight driving voltage or the motherboard driving voltage to a standby voltage. The voltage conversion circuit comprises an input terminal electrically connected to the first output terminal or the second output terminal and a third output terminal for outputting the standby voltage. The TV power supply can convert the backlight driving voltage or the motherboard driving voltage into the standby voltage through the voltage conversion circuit, and simultaneously generates the motherboard driving voltage, the backlight driving voltage and the standby voltage through a power supply, effectively reducing the number of the flyback power supply and reducing the TV power supply costs, and improving the cost competitiveness of the TV.
