Tp.v56.pb801 Schematic Diagram -

The TP.V56.PB801 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.

Cross-referencing real-world failure data with the schematic reveals:

| Reference Designator | Component Type | Failure Mode | How Schematic Helps | | --- | --- | --- | --- | | D502 | Rectifier Diode (SB5100) | Short circuit (no 12V output) | Shows diode is in parallel with output capacitor | | U301 | 1117-3.3 LDO | Input shorted, no 3.3V | Shows input comes from 5VSB; trace back | | C104 | SMD Ceramic (10µF) | Cracked, causing random reboots | Schematic indicates it is the filter for SoC reset pin | | Q601 | MOSFET (LED driver) | Drain-source short (backlight always on or off) | Identifies gate drive from PWM controller | | F1 | Fuse (3.15A 250V) | Blown | AC input section; check bridge rectifier after | Tp.v56.pb801 Schematic Diagram

The TP.V56.PB801 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
