Analog supply powering the source driver ICs and the Gamma circuit.
While a full internal circuit schematic is typically proprietary, the physical diagram of the board includes several critical sections: LVDS Input Connector:
: Optimized for Panda 43" UHD/FHD panels (e.g., CC430LV1D01). Version Variants : Often listed as compatible with CCPD-TC425-002 and STCON425G models.
Sources: Repair threads from DIY-LaptopRepair, KenotronTV, Yoreparo, and technical data from electronics supply databases.
The diagram maps out a highly popular Timing Controller (T-Con) logic board manufactured by Panda . It functions as the primary visual orchestrator for 43-inch LED televisions across brands like TCL, Philips, Hitachi, Westinghouse, Onn, and Haier . Responsible for translating low-voltage differential signaling (LVDS) data from the main motherboard into precise column and row commands for the liquid crystal display (LCD) panel, this board is a frequent target for DIY display repairs. Ccpd-tc425-001 Diagram
A small, 8-pin memory chip that stores the specific display panel's timing configuration, resolution parameters, and vendor initialization profile data.
Widely found in TV models like the TCL 43S5295/78G , 40S6500FS , 49S6500 , and 43S6300 .
The CCPD-TC425-001 T-Con hardware is versatile, acting as the logic backbone for budget and mid-tier televisions globally. It is widely deployed across a massive variety of brands utilizing Panda open-cell panel glass: Go to product viewer dialog for this item. CCPD-TC425-001 Logic Board T-CON Board For PANDA 43" TV
A schematic or functional diagram of the CCPD-TC425-001 typically highlights several key voltage test points and signal paths essential for display stability: Analog supply powering the source driver ICs and
Standard in various 43" Panda TV models (e.g., JVC, Xiaomi, Philips, Semp). Key Components: Typically integrated with a 10-bit Triple Channel ADC/PLL , LVDS transmitters, and a programmable timing controller. Operating Resilience: Often rated for high temperatures (up to 105℃). Connectivity:
Frequently linked to internal shorting in the panel glass rather than the T-CON board itself. Distorted Images: Can be caused by faulty LVDS or FFC cable connections. Technician Fixes: Gate Signal Blocking:

When diagnosing a faulty CCPD-TC425-001 board, standard diagnostic methodology requires measuring stable voltages at designated test points. Disruptions or short circuits at these locations will halt image generation completely. Test Point Label Description Expected Normal Voltage Range Role in Panel Operation Main Input Power +12.0 V Primary power feed from the TV motherboard. VDD / Vlogic Logic Core Voltage +3.3 V or +1.2 V Powers the central T-Con processor and digital logic gates. AVDD Analog Source Voltage +15.0 V to +17.0 V Supplies the Gamma reference array and source driver ICs. VGH / VON Gate Drive High Voltage +25.0 V to +32.0 V Turns on the thin-film transistors (TFTs) to refresh a row. VGL / VOFF Gate Drive Low Voltage -5.0 V to -7.0 V Holds the TFT pixel gates closed during the holding period. VCOM Common Reference Voltage +6.0 V to +7.5 V
Gate voltages responsible for switching pixels on/off.
