Tp.v56.pb801 Schematic Diagram

Check voltage across the main 450V filtering capacitor. It should read around (depending on regional grid inputs).

The TP.V56.PB801 is one of the most widely used three-in-one LCD/LED TV mainboards in the electronics repair industry. Manufactured by BoardTech (and various OEM facilities), this board integrates the main processor, a LED backlight driver circuit, and a power supply unit (PSU) onto a single substrate. It is commonly found in budget-friendly television brands ranging from 24-inch to 42-inch panel sizes.

is a highly versatile universal mainboard used extensively in various LED TV models, particularly in the 32-inch to 55-inch range . Whether you are a professional technician or a DIY enthusiast repairing an LCD/LED TV, understanding the is critical for efficient troubleshooting and repairs. This mainboard is known for its reliability but can suffer from common power or firmware issues.

Test the voltage at the LED output connector during boot up. If it stays at 12V without boosting, inspect the booster MOSFET, inductor, or check if the signal pin reads ~3.3V. Garbled Screen or Solid White Display LVDS Voltage / Signal Issue
