Introduction: Don't Toss the Whole PC — Just Swap the Panel

A cracked or black-screen Dell OptiPlex 7450 AIO or Inspiron 24 (5000 Series) doesn't mean the computer is dead. In over 90% of cases, the motherboard, CPU, RAM, and storage are perfectly fine — only the LCD panel is damaged.Both models share the same 23.8-inch FHD IPS display manufactured by LG Display: theLM238WF1-SLE1. This means one replacement panel fits both machines, making sourcing simple and cost-effective. A newLM238WF1-SLE1 paneltypically costs $80–$130, compared to $600+ for a brand-new AIO system.

Tools & Parts Checklist

Step-by-Step Disassembly & Replacement

Step 1 – Power Off & Remove the Stand

Unplug the AC adapter and all USB/peripheral cables. Lay the AIO face-down on a thick towel. Remove the two screws securing the stand bracket, then slide the stand off.

Step 2 – Remove the Rear Cover

Locate and remove all Phillips screws along the bottom edge and sides (typically 6–8 screws). Insert a plastic pry tool into the seam between the back cover and the front bezel. Work around the perimeter gently until all snap clips release. Set the rear cover aside.

Step 3 – Disconnect the Display Cables

You'll now see the mainboard and the back of the LCD panel.

• eDP (video) cable:Locate the 30-pin connector on the lower-left of the panel PCB. Peel back the adhesive tape, lift the locking flap, and slide the ribbon cable out.

• Backlight power cable:A smaller 2-pin or 4-pin connector near the top edge. Disconnect it.

• Touch cable (if applicable):On touch-enabled Inspiron 24 models, disconnect the USB touch ribbon as well.

⚠️Take a photo before disconnecting anything.This saves time during reassembly.

Step 4 – Remove the Broken LCD Panel

Unscrew the 4 bracket screws (two top, two bottom) holding the panel to the internal metal chassis. Tilt the panel forward slightly and lift it out. Place it face-down on a soft surface.

Step 5 – Install the New LM238WF1-SLE1

Unbox your replacementLM238WF1-SLE1panel. Handle it by the edges only — fingerprints on the polarizer layer are permanent.

• Align the new panel into the chassis brackets.

• Secure with the 4 screws (do NOT over-tighten).

• Reconnect the 30-pin eDP ribbon cable until the locking flap clicks shut.

• Reconnect the backlight power connector.

• Reconnect the touch cable if applicable.

Step 6 – Test Before Full Reassembly

Before snapping the rear cover back on, plug in the AC adapter and power on the system. Verify:

• ✅ Display lights up with no dead pixels

• ✅ Brightness adjusts normally

• ✅ Touch input registers (if applicable)

• ✅ No flickering or color banding

If everything checks out, power down, reconnect all internal cables, snap the rear cover back, reinstall screws, and reattach the stand.

Step 7 – Final Calibration

Boot into Windows →Settings → Display → Advanced Display Settingsand confirm resolution is 1920×1080 at 60Hz. Run Windows Update to ensure the Intel/AMD graphics driver is current.

Why Choose the LM238WF1-SLE1 Over Generic Panels?

Not every 23.8" panel is the same. TheLM238WF1-SLE1is the exact OEM part Dell specifies for the OptiPlex 7450 AIO and Inspiron 24 5000 Series. Using a mismatched panel can result in:

• Incorrect eDP pinout → no display

• Wrong backlight voltage → blown LEDs

• Mismatched bezel mounting holes → panel won't seat properly

Always confirm the part number printed on the back of the panel readsLM238WF1-SLE1(LG Display, Rev. 01 or later). You can verify availability and pricing on theLM238WF1-SLE1 product page.
