Understanding Color TV Technology
Before we dive into the troubleshooting process, it’s essential to understand how color TVs work. Color TVs use a combination of red, green, and blue (RGB) colors to produce a wide range of colors on the screen. The TV receives color information from the broadcast signal or external devices, such as DVD players or gaming consoles, and then processes this information to display the corresponding colors on the screen. If any part of this process is disrupted, it can result in a black and white display.
