If your Dell Chromebook 13 3380's display is cracked, shows lines, or stays dark even after replacing the display cable, the display panel itself may need replacement. Physical damage, pressure, or long-term wear can all lead to display failure. Before starting, power off and unplug your Chromebook, and disconnect the battery to prevent electrical damage. Take care not to scratch or bend the new screen during installation. If your troubleshooting ruled out cable or motherboard issues, follow this guide to safely replace the display and bring your Chromebook’s visuals back to life.
