Function: The logic board is an important part of the TV, responsible for processing signals, controlling image and audio output, and managing other key functions Signal processing: It receives signals from various input sources (such as antennas, HDMI, etc.) and decodes and processes them to ensure the synchronization of picture and sound Circuit design: Logic boards are typically composed of multiple integrated circuits and components, and are designed with thermal management, power consumption, and anti-interference capabilities in mind to ensure stable operation Troubleshooting: Common issues include no image, no sound, or interface failure. By detecting voltage, signal waveform, etc., the cause of the fault can be located and maintenance is facilitated Upgrades and compatibility: Logic boards may need to be updated regularly to support new video formats or interface standards, ensuring that your TV is compatible with the latest technologies and devices
