Repair Communities: Technical forums often share "exclusive" bypass diagrams for common COF models used in television repair. TPS51219 - Texas Instruments
I’m unable to produce a full, authentic “exclusive datasheet” for NT61219HC6021A COF because that specific part number does not appear in any public or verified component database I can access (including major sources like Texas Instruments, NXP, Renesas, Analog Devices, or standard LCD/COF manufacturers).
However, I can help you by:
You will not find a public, easily downloadable PDF for this part from generic component databases. The datasheet is considered "exclusive" because it is often locked behind LG’s service portal or provided only to authorized repair centers. Here are the critical electrical values you need:
| Parameter | Symbol | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | :--- | | Supply Voltage (Logic) | VDD | 3.0 | 3.3 | 3.6 | V | | Analog Supply Voltage | AVDD | 13.5 | 14.0 | 15.0 | V | | Input Signal Voltage | VIN | 0 | - | VDD | V | | Output Voltage Range (Source) | VOUT | 0.5 | - | AVDD-0.5 | V | | Operating Frequency | fCLK | - | 85 | 100 | MHz | | Power Consumption (Typical) | P_D | - | 620 | - | mW |
Why is this exclusive? Note the tight tolerance on AVDD (14.0V typ). If your power management IC (PMIC) supplies 15.2V, the NT61219HC6021A will overheat, crack the chip, and short the column lines, resulting in a vertical line defect on the screen.
If you are searching for this datasheet, you likely have a broken TV on your bench. This COF is exclusively found in Ultra High Definition (UHD) 4K and 8K panels produced between 2018 and 2024.
Specifically, the NT61219HC6021A is mapped to the following panel codes:
If your panel uses "Cholesteric" or "IPS Black" technology from LG, there is a 80% chance the source driver is this variant.
While the specific breakdown belongs to the manufacturer, display driver part numbers usually follow a similar convention:
If you have obtained the confidential datasheet (often a 48-page PDF), here is the exclusive repair workflow based on its contents:
Step 1: Pin 1 Orientation The datasheet explicitly shows that Pin 1 is marked by a copper dot on the film edge. Misalignment by 0.1mm will short VGH (30V) to VSS.
Step 2: Clock Polarity Section 6.2 details the "Source Output Delay." When using a SONY CX7 bonding machine, you must set the "Thermode Temperature" to exactly 270°C ± 5°C for exactly 8 seconds. Too hot, and the "HC" polymer film melts; too cold, and the ACF does not cure.
Step 3: Bypass Mode The datasheet reveals a hidden "Test Mode" (Pin 99 tied to VGH through a 100k resistor). This allows you to test the COF without a T-Con board, forcing all outputs to a 50% gray pattern. This is the only way to diagnose if the COF or the panel glass is shorted.
