Abstract
A method for controlling a volume level of a sound includes an input discrimination routine, a display routine, an increment routine and a decrement routine, whereby a maximum and minimum level of the PWM output are displayed on the screen. The routines are carried out by a MICOM for receiving a key-input signal and controlling a set. The method may reduce tint phenomenon of the screen by controlling the center level of an OSD(On Screen Display) using 0-64 levels for the OSD according to the output of the MICOM.
