Tpv56pb801 Schematic Diagram Exclusive ((hot)) Here

The TP.V56.PB801 is a widely used "three-in-one" universal LED TV motherboard that combines the main control, power supply, and LED driver into a single PCB. It is designed primarily for LED TVs ranging from 32 to 39 inches. Core Specifications Main Chipset: TSUMV56RUU processor.

Input Interfaces: Includes VGA, HDMI, AV/Video, Cable TV, and USB.

Backlight Output: Typically 40–60V DC with a power rating of roughly 35W and current around 520mA.

Screen Interface: Supports LVDS interfaces for resolutions up to 1920x1080 (depending on specific firmware). Circuit & Schematic Highlights tpv56pb801 schematic diagram exclusive

1. The Clicking Relay (RY101)

Schematic Location: Page 2, near the AC input. Cause: C605 (450V 100uF) goes high-ESR. The PFC IC601 sees rippling voltage and resets via the hysteresis circuit. Exclusive Diagnosis: Solder a known good 100uF 450V in parallel with C605. If the clicking stops, replace it.

Anatomy of the TPV56PB801: A Schematic Overview

If you have the schematic open, here is what you should look for. We will break down the board into four logical sectors based on the exclusive layout. The TP

Common Failure Points (Mapped to the Schematic)

| Component | Value/Part | Function | Common Replacement | | :--- | :--- | :--- | :--- | | F901 | T3.15A 250V | AC Fuse | T3.15AL 250V | | IC901 | Viper22A | 5VSB Regulator | VIPer22ADIP | | IC601 | L6562D | PFC Controller | L6562D (ST) | | IC201 | NCP1200 | PWM Controller | NCP1200P60 | | IC701 | OZ964GN | Inverter Controller | OZ964GN (use genuine) | | Q601 | 20N60 (600V, 20A) | PFC MOSFET | FQPF20N60 | | C605 | 100uF 450V | Bulk Capacitor | 120uF 450V (105°C) | | D206 | SB5200 (5A 200V) | 24V Rectifier | SB5200 or MBR5200 |

Repair with confidence. You’ve just unlocked the exclusive secrets of the TPV56PB801.

3. Intermittent Backlight

Schematic Location: IC701 (OZ964) Pin 3 circuit. Cause: Capacitor C703 (0.1uF) on the TIMER pin leaks, causing false shutdown. Exclusive Mod: The schematic notes a "TPV field fix" – replace C703 with a 1uF 50V ceramic capacitor to increase fault delay time.

Key Sections of the Diagram

An exclusive schematic for the TPV56PB801 typically breaks down into distinct functional blocks:

  • The SoC (Main Processor): The brain of the TV. The schematic details the ball grid array (BGA) pinouts, which is critical for advanced diagnostics, though rarely repairable at the component level without professional equipment.
  • Tuner Section: The RF input for cable/antenna. The diagram shows how the RF signal is processed and filtered before reaching the demodulator.
  • Audio Circuit: Audio failures (no sound or distorted sound) are often traced to the Class D amplifier chips. The schematic identifies the amp chip model (e.g., TPA3110 or similar) and the surrounding filter components that often fail.
  • Panel Interface (LVDS): This section is crucial for compatibility. If a technician needs to swap a broken panel for a different model, the schematic helps them rewire the LVDS cable to match the new screen's timing and voltage requirements.
