Do you need assistance locating the exact for a particular screen resolution?
When reviewing the official schematic diagram schematic for the TP.V56.PB801, you should look for several key nodes and test points designated by standard electronics labeling:
Before diving into the schematic subsections, it is vital to understand the operational boundaries and hardware capabilities of the TP.V56.PB801 board. TSUMV56RUU-Z1 (or variant TSUMV56RUE) TV Format: Analog/Digital (depending on the market variant) Panel Interface: Single or Dual-channel LVDS Supported Resolution: Up to 1920x1080 (Full HD) @ 60Hz Input Voltage: 100V–240V AC, 50/60Hz
The main microcontroller issues a BL_ON signal (approx. 3.3V) to turn on the boost controller chip. The brightness is regulated via a separate ADJ pin using duty-cycle modulation to dim or brighten the LEDs. D. The Controller and SPI Flash Subsystem Tp.v56.pb801 Schematic Diagram Pdf
Should read around 300V–340V DC (in 220V regions) or 160V–170V DC (in 110V regions).
A standard TP.V56.PB801 schematic is typically divided into the following functional blocks:

Understanding the hardware limits prevents component damage during repairs. TSUMV56RUU-Z1 TV Format: Analog signal support Panel Interface: Single or Dual Common LVDS Max Resolution: Up to 1920 x 1080 pixels (Full HD) Input Voltage: 100V to 240V AC Backlight Voltage: 45V to 94V DC Dedicated power lines for the internal DDR memory
High-value resistors (typically mega-ohm range) feed a small starting current from the 300V DC rail to the VCC pin of the PWM IC to initiate switching.
