Description
The Color TV Horizontal Deflection function is responsible for generating the high voltage signals that drive the horizontal deflection coil in the TV’s cathode ray tube (CRT). This coil is responsible for scanning the electron beam across the screen horizontally to create the picture.
This transistor is used in the circuit that controls the deflection coil, and it helps to amplify and regulate the current that drives the coil. This is important for ensuring that the electron beam is scanned accurately and that the TV produces a stable and high-quality picture.
The TT2222 transistor is a critical component of the Color TV Horizontal Deflection function in Samsung TVs, and it plays an important role in ensuring that the TV operates properly and produces high-quality images.
