Abstract
An electronic device having a self-diagnosis function is proposed. In the electronic device, a fault detector is provided on a primary side of a power board, so that fault states of a main board and a load may be detected even when the main board is broken or power is not applied to the main board. In addition, as long as commercial alternating power is input, even in a state where a power switch is turned off, the electronic device is supplied with the power, so that various types of faults in the main board and the load may be detected.
