A cracked laptop screen looks dramatic, but replacing an LCD panel is one of the more straightforward laptop repairs — usually involving nothing more than a screwdriver, some patience, and a correctly matched replacement panel. This guide covers how to identify the right part, remove the old panel safely, and fit the new one without damaging the delicate cables underneath.

Confirm it's actually the panel

Before ordering a replacement, make sure the crack itself is the fault, not a symptom of something else:

  • Visible spidering cracks, ink-like bleeding, or patches of black/discoloured liquid under the glass confirm physical panel damage.
  • If the display shows corruption or flicker but has no visible crack, read our guide on diagnosing a flickering screen first — you may not need a new panel at all.
  • Shine a torch at an angle across the screen while it's on. If you can faintly see a desktop image despite a "black" screen, the panel may be intact and the backlight or cable is actually at fault.

Step 1: Identify the exact panel model

This is the step most people get wrong, and getting it wrong means returns, delays, or a panel that physically doesn't fit.

  1. Power off the laptop and remove the current panel far enough to read its label (see removal steps below), or check the underside of your laptop and the original order confirmation for the exact model number.
  2. Look for a sticker on the back of the LCD panel itself — not the laptop chassis. It will show a part number, usually starting with letters like LP, N, B, or LTN followed by a series of digits (e.g. LP156WF6-SPB1).
  3. Note the size (measured diagonally, e.g. 15.6"), resolution (Full HD 1920×1080, HD 1366×768, etc.), and connector type (usually 30-pin or 40-pin eDP for modern laptops).
  4. Check whether your laptop uses a touchscreen panel — touch and non-touch panels are not interchangeable, and touch panels often have a digitiser cable in addition to the display cable.
  5. Search the exact part number on a specialist laptop screen retailer rather than a generic marketplace listing, and cross-check compatibility against your laptop's model number.

Pro tip: If two panels share the same resolution and size but have different part-number suffixes, they can still differ in connector pinout or brightness (nits). Always match the full part number where possible, not just the size and resolution.

Step 2: Prepare your workspace and tools

You'll typically need:

  • A small Phillips (PH0/PH00) screwdriver set
  • A plastic pry tool or old bank card
  • Tweezers for handling connectors
  • A magnetic parts tray or small containers for screws
  • An anti-static wrist strap (recommended, not essential)
  • Good lighting and a clear, padded work surface
  1. Shut the laptop down fully (not sleep) and unplug the charger.
  2. Remove the battery if it's user-removable. On laptops with internal batteries, hold the power button for 30 seconds after unplugging to discharge residual power.
  3. Ground yourself by touching an unpainted metal surface, or wear an anti-static strap.

Safety warning: Never work on a laptop's internals while it's connected to mains power, and always let a recently cracked screen fully settle before handling — broken glass and plastic edges can be sharp. Wear gloves when removing a shattered panel.

Step 3: Remove the bezel and old panel

Exact steps vary significantly by brand and model — check your manufacturer's service manual where possible, as screw locations and clip layouts differ. As a general process:

  1. Remove the screen bezel. Most laptops hide bezel screws under small rubber caps or stickers near the hinges — gently pry these up with a spudger to reveal the screws beneath.
  2. Unclip the bezel. Starting at a bottom corner, work a plastic pry tool around the inside edge of the bezel, gently releasing plastic clips as you go. Go slowly near the hinges, where clips are often more fragile.
  3. Unscrew the panel from the lid. With the bezel off, you'll see 2–4 screws (often on brackets at each side) holding the panel to the back cover. Remove these and support the panel with one hand.
  4. Disconnect the display cable. Gently tilt the panel forward, locate the ribbon cable connector (and digitiser cable if touchscreen) on the back, and carefully lift the connector's retaining flap if present before sliding the cable out. Never pull directly on the ribbon — always release any locking tab first.
  5. Remove mounting brackets if your new panel doesn't come with its own — most replacement panels ship without brackets, so you'll transfer the small L-shaped brackets from the old panel to the new one, usually held by two tiny screws per side.

Step 4: Fit the new panel

  1. Attach the mounting brackets to the new panel in the same orientation as the old one.
  2. Connect the display cable first, before securing the panel in place — this is much easier with the panel loose in your hands.
  3. Ensure the connector is fully seated and any locking flap is pressed back down.
  4. Test before closing up. Reconnect the battery (or power) and turn the laptop on with the bezel and screen still loose, to confirm the new panel displays correctly before you commit to reassembly. Check for dead pixels, even backlighting, and no flicker.
  5. Once confirmed working, power off, screw the panel into the lid, reconnect the cable if you disturbed it, and refit the bezel — starting the clips from the same point you started removal.
  6. Replace all bezel screws and rubber caps/stickers.

Common mistakes to avoid

  • Forcing a ribbon cable connector without releasing its locking flap — this tears the delicate copper traces and destroys the cable.
  • Buying a panel by screen size and resolution alone without checking the connector pin count.
  • Over-tightening bezel screws, which can crack the new bezel or the panel itself.
  • Skipping the "test before closing up" step, then having to fully disassemble again to fix a bad connection.
  • Routing the cable through the hinge incorrectly, causing it to be pinched and fail again within weeks.

Warning: If your laptop has a webcam, microphone, or Wi-Fi antenna wires routed along the bezel or lid edge, note their exact path with a photo before removal — misrouted antenna cables cause poor Wi-Fi reception, and a trapped webcam cable can be severed when the bezel is refitted.

Still not fixed?

If the new panel shows the same fault as before (flicker, no image, lines), the problem likely isn't the panel at all — it's the video cable, the graphics chip, or the motherboard's display connector. In that case, revisit our flickering screen and no-display troubleshooting guides before buying a second panel.

When to call a professional

If your laptop's screen is fused to the lid using strong adhesive rather than screws — common on many modern ultrabooks and most MacBooks — panel replacement requires precise heat application and specialist tools to avoid damaging the lid or cracking a second panel during removal. Similarly, if you're not confident handling ribbon cable connectors, or the crack has damaged the surrounding hinge or lid casing, a professional repairer will have the experience and correct parts on hand to do the job safely in one sitting.
