TP.V56.PB801 is a universal 3-in-1 LED TV motherboard that integrates the power supply, LED backlight driver, and TV signal processor onto a single PCB. It is widely used to repair or upgrade 32 to 55-inch LCD TVs. Installation Guide

Installing this board requires careful handling of high-voltage components and precise wiring. You can find detailed technical documentation and downloads on Elektrotanya Manuals.plus Safety Preparation tpv56pb801 schematic diagram install

: Wear an anti-static wristband and ensure the TV is completely unplugged. Wait at least 10 minutes

for internal capacitors to fully discharge before opening the chassis.

: Disconnect all existing cables (LVDS, backlight, speakers, keypad). If a connector has a locking buckle, press it first—never pull on the wires directly. Unscrew and remove the old board. : Align the TP.V56.PB801

with the original screw holes. Use moderate force to secure it; over-tightening can crack the PCB Wiring and Connections Power Input : Connect the AC power lead to the marked input terminals. LVDS Cable

: Match the pinout of your panel. Ensure the VCC (power) pin (often 5V or 12V) matches your panel's requirements to avoid destroying the screen. Once you have the PDF, open it and

: Plug the LED strips into the backlight output. This board supports various power modes (e.g., 35W or 45W) to match different screen sizes. Control/IR : Connect the remote receiver (IR) and button keypad. Configuration

: After assembly, you may need to install the correct firmware via a USB drive to match your panel's resolution (e.g., 1366x768 or 1920x1080). Key Schematic Details Power Section

: Includes a bridge rectifier and filtering for standby and main voltages (12V and 19V typically). Backlight Driver : Output voltage ranges between 45V and 94V depending on the specific model configuration. Interfaces

If you are repairing a modern LCD or LED television, chances are you have encountered a power supply or combo board labeled TPV56PB801. TPV Technology (Top Victory Electronics) is one of the world’s largest monitor and TV OEM manufacturers, supplying boards for brands like Philips, AOC, Envision, Sanyo, and even some Westinghouse or Element TVs.

The TPV56PB801 is not a single board but a series of power supply/LED driver boards found in 32-inch to 55-inch models. Without the correct schematic diagram, troubleshooting no-power, backlight, or audio issues becomes guesswork.

This article explains:

⚠️ Safety Warning: Power supply boards contain high-voltage capacitors (up to 450V) that can hold a lethal charge for days. Always discharge the main filter capacitor using a 10kΩ/5W resistor before probing or installing.
