The is a universal LCD/LED controller board (mainboard) widely used in the repair and refurbishment of LED televisions. It is a high-performance, integrated board designed to support LED backlight panels with a resolution support up to Full HD (1920x1080). This board is popular in the repair market due to its versatility, low power consumption, and integrated design, often serving as a direct replacement for failed proprietary boards in brands such as Samsung, LG, Hisense, and various OEM brands.
The is a universal "three-in-one" LED TV motherboard that integrates the power supply, LED backlight driver (inverter), and main signal processing board into a single unit. It is widely used in 32-inch to 50-inch LED/LCD TVs as a cost-effective replacement for boards like the TP.V56.PB726 or TP.VST59S.PB801. Technical Specifications
Some technicians share PDF schematic diagrams through direct links. Common Faults to Watch For Tp.v56.pb801 Schematic Diagram
Understanding the pinouts is critical for troubleshooting and panel matching.
When swapping a TP.V56.PB801 board or changing panels, you may encounter an upside-down picture or distorted colors (Jeida/VESA mapping mismatch). Instead of changing components, you can adjust these settings via software. The is a universal LCD/LED controller board (mainboard)
If you need help diagnosing a specific fault on your board, please tell me what your TV is showing (e.g., blinking light, completely dead, clicking sound) and what voltages you have measured so far so I can help you point out the exact component to check. Share public link
Use an oscilloscope or digital multimeter to test the supply voltage at . It must read a stable 3.3V DC . The is a universal "three-in-one" LED TV motherboard
The "TP" designation often refers to a reference design from a large ODM (Original Design Manufacturer) like TPV Technology (Top Victory), which manufactures for Philips and others. The indicates the processor generation (often an MStar or Novatek chip), while pb801 is the specific PCB revision.
: The primary switching controller switches a high-voltage MOSFET to pass current through the main transformer, generating secondary isolated voltages. 2. DC-DC Step-Down Converters (Secondary Rail)
The Tp.v56.pb801 is not a complex aerospace board, but its multi-layer design and surface-mount components make visual tracing nearly impossible. A schematic diagram provides:
A jumper or circuit that allows switching the LVDS supply voltage between 3.3V, 5V, or 12V. 5. IR and Keypad Connector
