A lamp driving apparatus of a liquid crystal display device and method of driving lamps in a liquid crystal display are described. The lamp driving apparatus includes lamps that irradiate a liquid crystal display panel with light. An inverter receives a DC voltage from an exterior voltage source, converts the DC voltage into an AC signal and supplies the converted AC signal to the lamps. A feedback circuit is arranged between the inverter and the lamps. The feedback circuit detects currents from the lamps. An inspecting part is disposed between the feedback circuit and the lamps. The inspecting part contains light emitting devices to determine if each of the lamps is operating normally or has an abnormality.
