PURPOSE: A device for automatically correcting an audio signal in a video display and a method therefor are provided to automatically correct an output level of an audio signal even if a channel is changed. CONSTITUTION: A microcomputer(370) stores an output level of an audio signal output from an audio processor(340) in regard to the current channel in an inner register, and examines whether a channel change signal is inputted. If the channel change signal is inputted, a comparator(342) compares the output level of the audio signal to a preliminarily stored channel before change with an output level of the audio signal to a channel after change. A level adjusting unit(344) adjusts the output level of the audio signal output from the audio processor according to the result of the comparison of the comparator.
