Tp.v56.pb801 Schematic Diagram Pdf Jun 2026

When using these resources, always verify compatibility with your specific board revision, LCD panel, and flash memory chip to avoid bricking the device.

Supports outputs between 45V–94V, typically for single-row backlight setups under 45W.

Once the power crosses to the cold side, the main secondary voltage (usually 12V) is distributed and stepped down further to power the control circuitry: Powers USB ports and standby circuits. Tp.v56.pb801 Schematic Diagram Pdf

Unplug the AC cord, remove the USB drive, and power the television back on to access the service menu for further calibrations. How to Access the TP.V56.PB801 Service Menu

Converts AC mains voltage to low-voltage DC for components. When using these resources, always verify compatibility with

Pin 8 of the Flash IC must read exactly 3.3V DC. 4. DC-to-DC Step Down Voltage Regulators

Supplies the core logic processing power of the TSUMV56 processor. 3. LED Backlight Driver Circuit Unplug the AC cord, remove the USB drive,

The Power Supply Unit (SMPS) Block

The primary power section converts high-voltage AC mains (100V-240V) into low-voltage DC rails.

Measure voltage across the large 450V filter capacitor (should be around 300V–340V DC).
