Genuine Dell Precision M4400 CCFL LCD ribbon cable

This is a genuine Dell OEM replacement ribbon cable for the Precision M4400 laptop. It is compatible only with 15.4 inch CCFL backlit LCD screens. The part number D966P matches the JAL21 CCFL cable and DC02C00080L identifiers found on the original component. Verify your part number before ordering as multiple ribbon cables exist for this model.

Single cable for CCFL panel replacement

The cable connects the motherboard to the CCFL inverter and LCD panel in the 15.4 inch display assembly. It handles the video signal and backlight power for CCFL technology only. It will not fit M4400 systems equipped with LED backlit screens. Buyers needing a cable for an LED panel or a different laptop model must source the correct separate part number.

Tested working pull with no extra power draw

This is a working pull that has been tested for continuity and signal integrity. As a passive ribbon cable it adds no power consumption, generates no heat and produces no noise during operation. Installation requires disassembly of the display lid and careful routing through the hinge area to avoid pinching the fragile conductors.

Questions about this item

Will this D966P cable fit the CCFL display on my Precision M4400 without replacing the inverter?

Yes, the D966P ribbon cable is designed for Precision M4400 models with 15.4 inch CCFL backlit screens and connects the panel directly to the motherboard without requiring a new inverter.

How can I confirm the cable is seated correctly after installation?

Power on the M4400; the CCFL backlight should illuminate evenly across the 15.4 inch panel with no flicker, pink tint or dark bands, and the Dell BIOS logo must appear without external monitor assistance.

Does the package include the JAL21 CCFL cable only, or are the display hinges and bezel screws supplied as well?

You receive exactly the D966P ribbon cable shown in the photo — part numbers JAL21 CCFL CABLE and DC02C00080L — hinges, bezel screws, inverter or LCD panel are not included and must be sourced separately.
