The T-Con board serves as the intermediary translator between your television's main logic board and the actual LCD glass panel. It dictates exactly when pixels fire. T-Con boards built on this substrate are prominently integrated into brands like . 2. LED Backlight Driver Strips
: Supports various resolutions and panel types, such as the InnoLux V320BJ8-Q01 panel.

PART NUMBER: 3KFDK1S51. BOARD NUMBERS: E88441, MV-0S 94V-0. MODEL NUMBERS: LC-75N8000U. TYPE: T-Con, LED, 75" Cmo Innolux Mv-0s94v-0 E88441 T-con Board For Hisense
| | Likely Cause | Recommended Solution | | :--- | :--- | :--- | | No image, but backlight and sound are present | Primary suspect: DC-DC converter failure . Voltages VGL (-5V to -10V) and VGH (+20V to +30V) are reading zero. This points to a failed IN635 controller IC on the T-Con board. | 1. Check and measure VGL and VGH. 2. If zero, inspect the DC-DC converter section. 3. Direct replacement of the IN635 chip or the entire T-Con board is the most reliable fix . | | Backlight present, but no image | Corrupt firmware in the EEPROM (e.g., GD25Q64 ). A corrupted or blank EEPROM can leave the panel uninitialized. | Reflash or replace the EEPROM chip . Firmware for this board is available from remont-aud.net. | | Inductor failure | One user reported that a faulty inductor on the E88441 board caused a no-picture issue. | Inspect and test all inductors for continuity and correct inductance . | tpts mv-0s 94v-0 e88441 pdf
The acronym typically stands for the manufacturer. In the electronics supply chain, this often refers to Top Tech System or a similar PCB fabrication house. This part of the label identifies who fabricated the bare board, which is essential for quality control and sourcing replacements.
If you are looking for the structural properties (layer thickness, chemical tolerances, and temperature limits) of the board material itself, you can consult the official Techvest ISO Material PDF via TPT-PCB . This lists the performance characteristics under registration file E88441 . The Functional T-Con/Display Manual
According to repair forums, these are the most frequent problems and their solutions for this board:
This is a technical blueprint. If you are an engineer or a repair technician, this PDF is vital. It typically contains: The T-Con board serves as the intermediary translator
: Operates strictly between 60MHz and 110MHz to ensure synchronized pixel timing.
(Gate Low) : Negative bias voltage (-5V to -15V) required to tightly close the TFT transistors, eliminating pixel bleeding. Common Failure Modes & Diagnostic Checkpoints
: Responsible for mapping data and power from the mainboard to the display, including RGB data, clock signals, and control lines.
The marking represents a high-quality, UL-recognized printed circuit board (PCB) predominantly found in consumer electronics, particularly within T-Con (Timing Controller) boards for LCD and LED televisions. This identifier combines several manufacturing, safety, and certification standards. PART NUMBER: 3KFDK1S51
: This is a UL 94 Flammability Standard rating. V-0 signifies that the PCB material self-extinguishes within 10 seconds of a flame being applied, and does not produce burning drips. This is the highest standard for safety in consumer electronics.
As this is a UL-certified component, the primary "datasheet" is the UL Certification Document.
The 94V-0 designation is a UL safety standard indicating the board material is highly flame-retardant and will self-extinguish within 10 seconds during a vertical burn test.
: Images appear washed out, looking like a photographic negative. Colors may bleed into each other, or fast-moving items leave severe trails. This signals a breakdown in the gamma reference voltage IC on the board.
