Method for self-diagnosing a television receiver

Abstract

A method for self-diagnosing a television(TV) receiver, wherein the TV receiver has a controller, which includes a central processing unit, a read only memory, a random access memory(RAM) and an erasable-programmable read-only memory (EPROM), for controlling the self-diagnosing and a power supply unit for producing both an initial power for driving the controller and an operational power for driving other units of the TV receiver except for the controller, comprises the steps of: (a) determining whether the initial power is applied; (b) first self-diagnosing the TV receiver, if the initial power is supplied, so as to determine either to wait a turn-on signal to turn the TV receiver on or to produce an alarm signal warning an abnormal state; (c) determining whether the turn-on signal is received; and (d) second self-diagnosing the TV receiver while the operational power is activated by the received turn-on signal, to produce a result of the second self-diagnosis onto a screen of the TV receiver.
