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 televisioncomprising a power supply circuitthat produces and outputs various power supply voltages from an inputted commercial AC power supply, a microcomputerthat outputs a control signal to a plurality of circuits, respectively, including at least the power supply circuitand an inverter circuitthat is driven by a power supply voltage output by the power supply circuitto controls turning on and off of each circuit, is provided with an input terminalfor providing a power supply voltage from the outside of the liquid crystal television, and an inspection auxiliary circuitconnected to the power supply circuitand inverter circuit, generating a constant voltage that starts the power supply circuitand inverter circuitwhen a power supply voltage is provided from the input terminaland outputs the constant voltage as a control signal.
