⚠ Critical Before Ordering:

Non-Touch models only. This panel uses a 30-pin eDP connector and is strictly for non-touch configurations. Touch-enabled models use a 40-pin connector and a different panel — these are not interchangeable. Fitting a non-touch panel to a touch chassis will result in a non-functional display.

Verify your connector pin count before ordering. Check the existing display cable in your laptop or your Dell service tag configuration to confirm non-touch.

OEM panel supplier may vary. Dell sources this panel from multiple manufacturers including Innolux (N156HCA-E5A), BOE (NV156FHM-N4H), and AU Optronics (N156HCA-E5A). The physical dimensions, connector, and performance specifications are identical across all OEM variants.

Installation Notes for Technicians

  • Direct Plug-In Replacement: No adapter, cable modification, or BIOS change required. The eDP cable, mounting rails, and bezel from the original screen are all reused. Transfer the side mounting rails from the old panel if they are not included.
  • Mounting Rail Screws: The display cable bracket is secured with two M2×3 screws. These are small and easily lost during disassembly — use a magnetic parts tray.
  • Cable Seating is Critical: Ensure the 30-pin eDP connector is fully and squarely seated. A partially connected cable on this platform typically produces a completely blank screen (not a partial image), which can be mistaken for a faulty panel.
  • Cross-Generation Fitment: The KFMYW panel fits across the Precision 3540 through 3571 series — the lid dimensions and eDP cable connector are consistent. Verified cross-generation swaps are a common part of workshop stock management.
  • Service Manual: Dell's official Precision 3550 Service Manual documents the LCD assembly removal and installation procedure step by step, including torque specs for the hinge and bezel screws. Available free on Dell's support site.

Frequently Asked Questions

Will this screen fit my Dell Precision 3550?

Yes — provided your Precision 3550 has a non-touch display. The KFMYW is the standard OEM FHD non-touch panel for the Precision 3550. If your original screen is touch-enabled, this panel is not compatible. Check your Dell service tag or the existing display cable pin count (30-pin = non-touch, 40-pin = touch).

Do I need any special tools or cables to install this screen?

No additional cables or adapters are required. The existing 30-pin eDP display cable in your laptop connects directly to this panel. You will need a small Phillips-head screwdriver (PH0 or PH00) and a plastic pry tool to remove the display bezel. Dell's service manual for the Precision 3550 provides full step-by-step guidance.

Is this a genuine Dell OEM part?

Yes. This is sold under the genuine Dell part number KFMYW / 0KFMYW. The underlying panel is manufactured by Innolux (model N156HCA-E5A) — the same OEM supplier Dell uses in original production units. Dell sources this part from multiple OEM panel manufacturers; the displayed specs and physical dimensions are identical across all variants.

What if the screen is blank after installation?

A completely blank screen is most commonly caused by the eDP cable not being fully seated. Power down, carefully reseat the 30-pin connector ensuring it is square and fully clicked in, and retry before assuming the panel is faulty. Also confirm the display cable bracket screws are reinstalled, as a loose bracket can allow the connector to partially disengage.

Can this panel replace screens on other Dell models?

Yes. The KFMYW is a shared platform panel used across Dell Precision 3540–3571 and Latitude 5500–5521 series laptops. It is a versatile part for repair workshops servicing multiple Dell business laptop models. See the compatibility table above for the full confirmed model list.

Is this screen suitable for upgrading from a lower-spec panel?

Yes, provided the machine has a 30-pin eDP cable fitted. Some base-specification Precision 3550 units shipped with a TN panel — replacing with this IPS panel is a direct upgrade for colour accuracy and viewing angles. No driver or BIOS changes are required.

Warranty

This replacement LCD panel is covered by a 3-month warranty from Reboot IT against manufacturing defects and dead-on-arrival faults. The warranty covers panel defects including dead pixels (above manufacturer threshold), backlight failure, and connector faults under normal operating conditions.

Physical damage caused during installation, incorrect fitting to incompatible hardware (e.g. touch chassis), or damage from electrostatic discharge is not covered. We recommend handling the panel by its edges and using an anti-static mat during installation.

All warranty claims are handled directly by Reboot IT's support team. Contact us with your order number and a description of the fault.
