A television steering coil control circuit is a type of electronic circuit that controls the horizontal and vertical movement of the electron beam in a television set, which is responsible for creating the images on the screen.
The circuit uses a combination of resistors, capacitors, and transistors to generate signals that control the positioning of the electron beam. These signals are sent to the steering coil, which creates a magnetic field that moves the beam horizontally and vertically across the screen.
Without this circuit, the electron beam would not be able to move accurately and precisely, resulting in distorted or incorrect images on the screen. The circuit is essential for the proper functioning of a television set.
The most common problems with this circuit include faulty connections, damaged components, and malfunctioning transistors. These issues can lead to issues with the horizontal or vertical movement of the electron beam, resulting in distorted or misaligned images on the screen.
If the issue is caused by faulty connections, they can be easily repaired by re-soldering or replacing the damaged wires. In the case of damaged components, they will need to be replaced with new ones. Malfunctioning transistors can also be replaced, but it is recommended to seek the help of a professional technician for this task.
