Abstract
A fine adjustment tuning apparatus for televisions includes a key matrix part, a microcomputer part, a local osicillating part, and a red/green/blue mixer part. The method of storing the tuning data includes an initial mode setting step, an on screen display displaying step, a storing deciding step, an input time detecting step, and a key input routine implementing step.
