is a popular, high-performance universal combo main board commonly used in smart LED TVs, ranging from 32 to 50 inches. It integrates the power supply unit (PSU), LED driver, and main board into a single PCB, making it a "3-in-1" board. This board is known for its versatility across various brands including TCL, Skyworth, and other Android-based smart TVs.
: The TP.MT5510I.PB805 can support different resolutions. The schematic helps identify the configuration resistors or software settings to correctly match an HD (1366x768) or Full HD (1920x1080) LCD panel, which is vital when replacing a faulty screen.
You will often find boards with very similar codes. The two most common variants related to the are:

Disclaimer: Repairs should be conducted by trained professionals. High voltage is present on the board.
The power supply section converts high-voltage AC mains input into regulated DC lines to feed the rest of the board.
The MediaTek processor requires multiple ultra-stable low voltages to operate. Micro-step-down regulators convert the +12V or +5V rails into: CPU Core Voltage (V_Core). 1.5V – 1.8V DC: DDR RAM power supply. 3.3V DC: EMMC flash storage and standby logic. 5.0V DC: USB ports and panel VCC (selectable via jumper). 3.
