The brain of the board. It processes video signals from HDMI/VGA and generates the LVDS signal for the panel. A 12MHz crystal is connected to the chipset.
To set the correct resolution, the correct software must be loaded into the SPI flash via a USB drive or a programmer like the CH341A. 5. Summary and Component Identification tpv56pb801 schematic diagram exclusive
Having this diagram transforms a "throw-away" board into a repairable asset. It enables:
: By combining the driver control, power management, and display interface, this board simplifies repairs but makes the circuit diagram more complex as it covers multiple high-voltage and low-voltage sections. Power & Backlight : A direct link to an updated PDF
This board is also known for being compatible with various LCD panels, as different TV brands have used it in their models. It's common to find it in brands like [16†L6][11†L3][17†L4][17†L12]. You may also encounter slight variations of the same board, such as the TP.VST56.PB801 , which often has identical hardware but different firmware [18†L21-L22].

Modern TVs are essentially computers. They rely on a BIOS/Bootloader stored in a SPI Flash memory chip (often a 25Q series chip). The schematic reveals:
