If you can share any of the following from the actual datasheet, I’ll rewrite the post with precise specs:
Replacing a COF IC is not a DIY task for general consumers. It requires:
One open-circuit or broken track on the output side of the COF.
Unfortunately, manufacturers restrict full datasheets to qualified LCD panel makers. Your best sources: nt61219h-c6021a cof datasheet
While full internal schematics are often proprietary to manufacturers like Novatek, the following logistical and technical details are standard for this part: Application : LCD/LED TV panel repair and manufacturing. Package Type : COF/TAB (flexible film). Typical Pinout Signals
: 180°C to 210°C at 2.5 to 3.5 MPa of pressure for 12 to 18 seconds.
It converts digital image data from the television's timing controller (T-Con) into analog voltage levels. If you can share any of the following
Analog power supply driving the output operational amplifiers.
Apply localized heat (around 200°C) to soften the original ACF glue.
Thoroughly clean the ITO (Indium Tin Oxide) tracks on the glass edge. Remove all old adhesive residue using an ACF cleaning solution. The tracks must be mirror-clean. Your best sources: While full internal schematics are
The NT61219H-C6021A is available for purchase from specialized LCD component suppliers, primarily based in China, such as:
The Chip-on-Film technology integrates a highly dense silicon display driver integrated circuit (IC) directly onto a flexible printed circuit (FPC) substrate. This thin, flexible tape allows high-density output channels to connect the rigid glass panel (TFT matrix) to the display control circuitry (T-CON board). Key Structural Features: Novatek Microelectronics
In the repair industry, the NT61219H-C6021A is frequently sought after to fix specific screen defects. When this chip fails—often due to "gate/source COF burnout" or physical damage—the TV may exhibit: Vertical lines or bars on the screen. Half-screen blackouts or "frozen" images. Thermal failure (the chip becomes excessively hot). Sourcing and Replacement
