Abstract:
A television apparatus includes a front panel keyboard having first and second keys, and a controller for detecting a type of operational logic of the front panel keyboard. The controller applies a keyboard operational voltage to the front panel keyboard according to the detected type of operational logic. If the controller determines that the type of operational logic is negative, the controller applies the keyboard operational voltage to the front panel keyboard. Otherwise, if the controller determines that the type of operational logic is positive, the controller applies no keyboard operational voltage to the front panel keyboard.
