Understanding the TP.V56.PB801 LED TV Motherboard: A Technical Guide

  • Amplifier: Common chips include the TPA3110 or TPA3116.
  • The schematic shows the audio signal path routing from the MCU I2S outputs to the Amp inputs, finally driving the speakers through output filters (inductors and capacitors) to prevent high-frequency noise.

The schematic is divided into several critical power stages: Hot Side (Primary): Bridges the AC input to DC (approx. in 110V regions or in 220V regions). Cold Side (Secondary): Delivers isolated low voltages, typically for the mainboard and for the logic circuits. Backlight Driver:

The audio path consists of a digital-to-analog converter (DAC) feeding into a Class-D amplifier chip.
