It utilizes a boost inductor, a fast-recovery diode, a switching MOSFET, and a bank of smoothing capacitors to step up the voltage to the level required by the TV's LED strips.
Troubleshooting Tip: If the TV has no power light, check the fuse (F1), the MOSFETs in the buck converter circuit, and the diodes. 2. Backlight Driver (Inverter) Section
Centred around the TSUMV56RUU-Z1 processor, this section regulates lower voltages (
Dual-mode intelligent power supply supporting either 35W (45–65V / 480mA) or 45W (66–94V / 600mA) backlight configurations. Tp.v56.pb801 Schematic Diagram Pdf
The power supply section converts high-voltage AC mains into stable DC voltages. It occupies the "hot" side of the board (demarcated by a thick white line on the PCB). Key components in this schematic block include:
The TSUMV56 processor requires several distinct operating voltages to drive its core logic, analog-to-digital converters (ADCs), and peripheral I/O lines. Tracing the 12V output across the schematic reveals the following step-down infrastructure:
If you are currently working on a physical board, let me know what you are experiencing (e.g., blinking light, completely dead, no backlight) or if you need help identifying a specific component location code so I can guide you through the exact troubleshooting steps. Share public link It utilizes a boost inductor, a fast-recovery diode,
Consists of a fuse (usually 3.15A), varistor (VDR), and a thermistor (NTC) to guard against voltage spikes.
Check for stable 5V, 3.3V, and 1.2V rails. Corrupt SPI Flash Sound Present, No Picture (Flashlight Test OK) Backlight Driver
For repair attempts, focus on checking power supply rails, inspecting for bulging capacitors, and verifying the LED driver circuit. The community experiences documented in forums like EEVblog are your best guides. Key components in this schematic block include: The
Typically operates on an input range of 66–94V AC .
Before connecting a new board to a screen panel, locate the panel VCC selection section on the schematic. Ensure the physical jumper on the board is set correctly to 3.3V, 5V, or 12V to avoid permanently destroying the T-CON board of your LCD panel.
– Vendors on AliExpress/eBay selling the TP.V56.PB801 board sometimes provide a schematic or pinout upon request.
He could fix it. But without the official schematic—the one that matched his exact board revision—he couldn’t be sure he wasn’t missing another trap.
The is a highly integrated combination board (power supply + main board) commonly found in modern LED LCD TVs, particularly in budget to mid-range brands such as TCL, Hisense, RCA, and Philips. Unlike older TV designs that separate the power supply and signal processing, the TP.V56.PB801 integrates both onto a single PCB.
