What is the IC Vertical An15525?
The IC Vertical An15525 is a type of integrated circuit (IC) that is designed to control the vertical movement of the electron beam in a CRT TV. The electron beam is what creates the image on the screen by scanning across the phosphor-coated surface of the CRT. The vertical deflection output is responsible for moving the beam up and down, while the horizontal deflection output moves it left and right.
The IC Vertical An15525 can handle a maximum output current of 2 A [p-p], which means it can drive a large deflection coil with high power. This makes it suitable for driving 21 inch to 29 inch monitors. It also has a built-in pump up circuit and a thermal protection circuit to prevent damage from overvoltage and overheating. The IC Vertical An15525 has an absolute maximum rating of 80 V, which means it can withstand high voltage spikes without breaking down.
Why is the IC Vertical An15525 important for your TV performance?
The IC Vertical An15525 is important for your TV performance because it affects the quality of the image on the screen. If the vertical deflection output is not working properly, you may experience problems such as:
Vertical linearity distortion: This is when the vertical spacing between scan lines is not uniform, resulting in a distorted image.
Vertical foldover: This is when the top or bottom part of the image is folded over itself, creating a double image.
Vertical jitter: This is when the image shakes or vibrates vertically, causing a blurry or unstable picture.
Vertical collapse: This is when the image disappears completely or shrinks to a thin horizontal line.
These problems can be caused by various factors, such as faulty components, loose connections, dirt, moisture, or aging. To fix them, you may need to replace or repair the IC Vertical An15525 or other parts of the vertical deflection circuit. You may also need to adjust some settings or calibrate some components to improve the vertical alignment and stability.
How to find and replace the IC Vertical An15525 in your TV?
If you suspect that your IC Vertical An15525 is damaged or malfunctioning, you may want to find and replace it in your TV. However, this is not a simple task and requires some technical skills and tools. You should also be careful of the high voltage and current that are present in your TV, as they can cause electric shock or fire hazards. Therefore, it is recommended that you consult a professional technician or service center before attempting to do this yourself.
