What to Do When the LCD Won’t Display

Although the LCD on your laptop can fail, it’s unusual for this to happen. Modern laptop displays are surprisingly durable, unless you manage to drop your laptop to the floor with its lid open, or if you back up your car and pass over the computer you left in the driveway.

Keep in mind that in most situations, the average user should not attempt to manually repair an LCD. The parts are tiny and delicate and the working space inside a laptop would give an ant a cramp.

If your LCD suddenly stops working, take these steps:

  1. Reboot the laptop.

    See if this was a momentary failure.

    If you see the ordinary startup text on the screen (the name of your computer maker and some details about the model), go to the next step.

  2. Try to get to the BIOS setup screen.

    The text should tell you how. On many laptops you press one of the F keys or the Escape key during the bootup.

  3. Check the LCD settings.

  4. Reset the BIOS to its default configuration.

    Find the option that instructs the system to do that and hope the problem is fixed. Electrical surges, certain software conflicts, and some viruses can cause unwanted changes to the BIOS screen.

  5. Go to the step that suits your circumstances:

    • Step 6 if your laptop restarts and the screen works properly

    • Step 7 if all you see is a black hole, a bright line, or distorted bands of color or gray

  6. Run a full antivirus scan.

  7. Consider sending the laptop to the repair shop.
