: Likely a manufacturer or series identifier frequently appearing on LED backlight bars and display-related circuitry. Common Applications
: Certifies that the PCB material meets the UL 94 V-0 standard, meaning the plastic will self-extinguish within 10 seconds of being ignited.
: You can verify the safety registration and technical limits (like operating temperature and solder limits) via the UL Product iQ database.
This board is frequently associated with Chimei Innolux panels. Common Applications & Device Compatibility
: The UL File Number. This number is assigned to the manufacturer of the raw PCB material or the assembly plant (often identified as Primary Usage & Applications E88441 94V-0 tpts mv0s 94v0 e88441 pdf verified
Probe the pad. If it reads 0V or fluctuates wildly, the power management IC is either dead or protecting itself from a shorted ceramic capacitor. Step 3: Isolation Test for Panel Shorts
: This is a UL (Underwriters Laboratories) flammability rating , indicating that the plastic or PCB material is self-extinguishing within 10 seconds and does not have flaming drips. It is a standard safety certification found on almost all modern circuit boards.
When you download the PDF from a manufacturer (like TPV, Innolux, or LG), use a hash calculator to verify it against the checksum provided on the official support page. If even a single character differs, the file has been tampered with. This process is akin to checking a digital fingerprint.
: This is likely the specific model or family identifier for the T-CON board. : Likely a manufacturer or series identifier frequently
This is the standard UL 94 flammability rating . It verifies that the plastic and fiberglass substrate will self-extinguish within 10 seconds during a vertical burn test, ensuring fire safety inside high-voltage consumer electronics.
Decoding the Marking Codes: What is TPTS MV-0S 94V-0 E88441?
State whether the markings are consistent and authentic.
: This is a UL File Number assigned to Taiwan Printed Circuit Board Techvest Co Ltd (TPT) . It verifies that the PCB material meets specific safety and manufacturing standards under the ZPMV2 category . This board is frequently associated with Chimei Innolux
Disclaimer: This article is for educational and repair‑related purposes. Always follow safety procedures when working with electronic devices, and ensure any replacement component is correctly matched to your specific TV model.
: Disconnect one of the two flat cables running from the T-Con board directly to the LCD panel glass, then turn on the display. If one half of the screen displays a perfect image while the other side is disconnected, the T-Con board is likely fine, and the issue lies in a short circuit inside that specific side of the LCD panel itself. Precautions for Purchasing Replacements
: Directs a ladder of voltages ensuring uniform grayscale and color accuracy across the display. Common Failure Symptoms & Diagnostic Benchmarks
or "verified" manual for these parts, they are rarely released as standalone documents for consumer use. Instead, technicians typically use: Service Manuals : Search by the specific TV or laptop model number (e.g., Samsung LE40B551) rather than the PCB code. Parts Databases : Specialized retailers like
A UL flammability rating , indicating the board is made of flame-retardant materials that self-extinguish within 10 seconds and do not drip flaming particles.
If you have already ruled out the main board and the LCD panel (by performing a panel self‑test, for example), the T‑Con board is the next logical suspect. Because T‑Con boards are modular, they are often replaced rather than repaired at component level.
