This is a "Boost Converter" section. It takes the 12V rail and steps it up to the voltage required by your TV's LED strips.
: 2 × 3W or 2 × 5W (depending on configuration) Core Circuit Blocks of the Schematic Diagram
Typically uses an 8-pin PWM chip (such as LD7536, OB2273, or similar variants) to drive the high-voltage MOSFET.
Blown fuse or shorted MOSFET in the primary section.
Based on the findings of this report, we recommend that: Tp.v56.pb801 Schematic Diagram
This area includes the boost converter circuit (inductors and MOSFETs) designed to drive LED strips for screens ranging from 32 to 55 inches.
: The board is highly adaptable, supporting both LVDS and eDP display protocols. It serves as a direct replacement for older models like the TP.VST59S.PB716 Power Efficiency
Check the backlight driver circuit. Look for open LED circuits or damaged boost components in the circuit.
Supports analog and digital television signals (though specific tuning depends on the region-specific firmware). 2. Schematic Sections & Key Components This is a "Boost Converter" section
Holds the firmware. Pin 8 receives +3.3V VCC, Pin 4 connects to Ground, and Pins 1, 2, 5, and 6 handle data transmission. 3. Critical Voltage Test Points
Key components include buck converters designed to step down voltage for the processor and memory. 2. Main Processor (TSUMV56)
The center of the schematic details the pins of the . It manages:
is a combo board that combines the mainboard, driver board, and power supply unit into a single PCB. It is commonly found in 15-32 inch LCD/LED televisions and monitors. Key features include: Typically uses the TSUMV56RUET-Z1 chipset. Blown fuse or shorted MOSFET in the primary section
The is one of the most widely used three-in-one universal LCD/LED TV driver boards in the repair industry. It integrates the main processor, LED backlight driver, and power supply unit (PSU) into a single compact board. Navigating its schematic diagram is essential for successful component-level troubleshooting and repair.
The schematic diagram of this combo board is divided into four major functional blocks. Pinpointing a problem requires understanding how these blocks interact.
The Tp.v56.pb801 schematic diagram consists of various components, including:
