Because the substrate handles heat dissolution exceptionally well, it is widely utilized for long, narrow LED edge-lit or direct-lit backlight arrays. It supplies stable voltages to the string of diodes illuminating the screen.
The TPTS MV-0S 94V-0 E88441 PCB is commonly found in T-Con (Timing Controller) boards, which bridge the television's mainboard and the LCD panel.
Always ensure the Chimei Innolux panel number (e.g., V390HJ4) matches your original board, not just the TPTS PCB identifier, to ensure compatibility. Conclusion
. These boards are critical components used in various LED and LCD TV models from brands like Samsung, Sharp, and TCL to manage the data signal sent to the display panel. UL Product iQ Component Breakdown TPTS (or TPT) : The manufacturer, Taiwan Printed Circuit Board Techvest Co. Ltd. : The specific board model or layout designation.
: This is the official Underwriters Laboratories (UL) file number issued to Taiwan Printed Circuit Board Techvest Co Ltd. It acts as a traceability code certifying that the factory produces materials matching strict electrical safety and chemical resistance parameters. Where This Board Layering Is Used tpts mv-0s 94v-0 e88441 pdf
The identification code is commonly found printed on printed circuit boards (PCBs), particularly those used as T-CON (Timing Controller) boards in LCD and LED televisions. This code represents a specific manufacturing standard and identification, often linked to Taiwan Printed Circuit Board Techvest Co., Ltd., under the UL recognition number E88441 .
(though this may also be a mainboard issue).

: E88441 , which certifies the board meets specific safety and manufacturing standards for "Wiring, Printed - Component". Always ensure the Chimei Innolux panel number (e
The search term strongly correlates with firmware binaries and EEPROM dumps, primarily for T-Con boards. Repair forums and specialist sites host these files as critical tools for troubleshooting. For example, an EEPROM dump file from a working T-Con board is used to re-flash a corrupted chip on a non-working board.
: Refers to the specific substrate layer configuration and narrow trace architecture pattern. The "MV" family defines double-sided or multilayer metal-base printed wiring configurations.
: Often, when people search for these board numbers, they are troubleshooting a "no power" issue. Check for bulging capacitors or charred traces near the TPTS marking.
Sites like One River HK may have associated datasheets for the TPTS MV-0S94V-0 series 1.2.2. Summary Table Description Manufacturer Taiwan Printed Circuit Board Techvest Co., Ltd.
