Tp.v56.pb801 Schematic Diagram ((install))

TP.V56.PB801 is a widely used "three-in-one" universal LED TV motherboard that integrates the power supply, LED backlight driver, and TV tuner into a single PCB. It is a staple in the repair industry for reviving 32-inch to 46-inch LED TVs from brands like Orion, Elenberg, and Erisson. Core Architecture & Schematic Highlights

DC-DC Converters: Step-down regulators (often utilizing the IC1118 triple regulator) that provide stable 3.3V and 1.8V rails for the processor and memory. Tp.v56.pb801 Schematic Diagram

  1. Power Supply: Converts AC mains into DC voltages (typically 12V, 5V, 3.3V, and standby voltage).
  2. LED Backlight Driver: Provides the constant current necessary to drive the TV’s LED strips.
  3. Main Processor/TCON: Contains the system-on-chip (SoC) for video processing and often integrates the timing controller (TCON) logic.
  1. Resistors: These are devices that oppose the flow of electric current. They are represented by a zigzag line or a rectangular box with a value indicating their resistance.
  2. Capacitors: These are devices that store electric charge. They are represented by two parallel lines or a rectangular box with a value indicating their capacitance.
  3. Inductors: These are devices that store magnetic energy. They are represented by a coil or a rectangular box with a value indicating their inductance.
  4. Integrated Circuits (ICs): These are small electronic circuits that are fabricated on a single chip of semiconductor material. They are represented by a rectangular box with a number indicating their type and function.
  5. Diodes: These are devices that allow current to flow in one direction but block it in the other. They are represented by a triangle with a line across one of its vertices.
  6. Transistors: These are devices that amplify or switch electronic signals. They are represented by a circle with three terminals.

The TP.V56.PB801 is a widely used universal LED TV motherboard, often referred to as a "combo board" because it integrates the power supply, LED backlight driver, and the main logic board onto a single PCB. Understanding its schematic is essential for technicians dealing with common issues like "no indicator" or "standby" faults. Key Functional Sections Resistors : These are devices that oppose the

Backlight Voltage: Outputs ranging from 40V to 94V, with currents adjustable between 480mA and 600mA.

While the board itself may be inexpensive to replace (often $15–$25 on eBay), mastering its repair using the schematic diagram builds skills applicable to hundreds of similar TV main boards. Bookmark reliable schematic sources, understand the five key sections outlined above, and you will turn a frustrating "no power" complaint into a quick component-level fix.
