Compatible Dell Inspiron 14 7420 2-in-1

This replacement hinge assembly is built for the Dell Inspiron 14 7420 2-in-1 laptop. It integrates the FHD LCD touch panel with the hinge mechanism in one unit. The part matches Dell part numbers 28P7C and HWY0J. Professional installation is required because the assembly contains fragile glass components.

Verify exact back-label model numbers

The supplier stresses that many internal screen models look alike but differ in pin count, resolution or connector layout. Buyers must compare the numbers on the original screen’s rear label with the listing before ordering. If the details do not match, the screen will not display. Do not unseal the package if you suspect a mismatch.

No separate thermal or power specification

The hinge assembly draws power through the laptop’s internal display cable and adds no independent heat source. Normal operating temperatures and acoustics are governed by the host system’s cooling design. Disconnect the battery and AC adapter before fitting the part to avoid electrical damage.

Questions about this item

What does the 14-inch FHD touch screen deliver once installed in a Dell Inspiron 7420 2-in-1?

It restores the original 14-inch full-HD touch display with the correct hinge assembly so the 2-in-1 convertible function works exactly as designed.

Which connector standard does the assembly use and what does it limit?

The assembly uses the Dell-specific 28-pin eDP connector for the Inspiron 7420, limiting compatibility to panels that match that pin-out and signalling.

What physical mounting points does the hinge assembly require on the chassis?

It mounts to the existing hinge brackets and screw posts on the Inspiron 7420 lid and base, aligning with the factory hinge centres and display-cable routing clips.
