<p>PROBLEM TO BE SOLVED: To provide a circuit and a television apparatus therewith which control an LED current in a simpler configuration.SOLUTION: The circuit includes a synchronous drive section for generating a control signal in synchronization with an output pulse of an AC/DC converter, and an LED current control section for starting current control on an LED in response to the control signal, and outputting a signal to stop the control signal when detecting a predetermined LED current, and the synchronous drive section stops the control signal in response to the stop signal. The circuit further includes a current maintenance section serving to maintain the LED current.</p> |
