ABSTRACT:
The present invention discloses enabling readily determining which circuit, among a plurality of circuits including an optical source lighting circuit and a power supply circuit, has a failure and repairing the circuits easily in a short period. A liquid crystal television100comprising a power supply circuit24that produces and outputs various power supply voltages from an inputted commercial AC power supply, a microcomputer22that outputs a control signal to a plurality of circuits, respectively, including at least the power supply circuit24and an inverter circuit26that is driven by a power supply voltage output by the power supply circuit24to controls turning on and off of each circuit, is provided with an input terminal53for providing a power supply voltage from the outside of the liquid crystal television100, and an inspection auxiliary circuit50connected to the power supply circuit24and inverter circuit26, generating a constant voltage that starts the power supply circuit24and inverter circuit26when a power supply voltage is provided from the input terminal53and outputs the constant voltage as a control signal.
