Step-by-Step Repair

  1. Step 1 of 6
    1

    Perform a hard restart

    Turn the device completely off. For electronics, hold the power button for 15-30 seconds. Wait a minute, then turn it back on. This clears many software-related display issues.

  2. Step 2 of 6

    Check all cable connections

    If applicable, check HDMI, display, and power cables. Unplug and firmly replug each one. Try different cables and different ports if available.

  3. Step 3 of 6

    Adjust brightness and display settings

    The screen may be working but with incorrect settings. Try adjusting brightness. If using a remote, try pressing the Input or Source button to cycle through input sources.

  4. Step 4 of 6

    Test with an external display

    If possible, connect to an external monitor or TV. If the external display works fine, the issue is with the device's screen specifically, not the graphics processor.

  5. Step 5 of 6
    5

    Check for physical damage

    Look closely at the screen for cracks, pressure marks, discoloration, or dead spots. Shine a flashlight at the screen — if you can faintly see the image, the backlight may have failed.

  6. Step 6 of 6

    Update software/firmware

    If the device powers on but the display is acting up, check for software updates. Display glitches are sometimes caused by buggy software and fixed with an update.

If That Didn't Work

  • Try a hard reset: unplug the charger, remove the battery if possible, hold the power button for 30 seconds.
  • Boot into Safe Mode to check if the issue is software-related.
  • Check if an external monitor works to rule out screen vs. GPU issues.

When to Call a Professional

If the motherboard or GPU is the issue, repair costs can run $200-$500. At that point, compare with the cost of a refurbished or new laptop. If your laptop is over 4-5 years old, replacement is usually the better investment.
