Genuine Dell OEM Replacement Cable

This genuine Dell OEM LCD ribbon cable carries the part number TPN7R and is built for the Latitude 7420 2-in-1 with a 14 inch touchscreen. It matches the factory specification for the optional 6 mm infrared camera module. You receive exactly the component shown in the product imagery.

Replaces a Damaged Factory Ribbon

The cable replaces the original display flex when the hinge assembly frays, the panel flickers or the IR camera stops responding. Swapping the ribbon restores the video path and camera function without replacing the entire lid assembly. The repair is worthwhile when the laptop chassis remains sound and only the cable has failed.

Verify Model and Camera Option First

Confirm the service tag reads Latitude 7420 2-in-1 and that the system shipped with the 6 mm infrared camera configuration. The connector layout differs on non‑IR and non‑touch variants, so an incorrect cable will not seat properly. Check the existing part label against TPN7R or the alternate codes GDB43_EDP_CBL_6mm_RGBIR_FHD and DC02C00RB00 before ordering.
