Use this guide to replace the LCD cable in your Lenovo ThinkPad T480s laptop.
Some signs your LCD cable may be faulty include a blank, black, or flickering screen, no backlight, or horizontal or vertical lines. These symptoms may also indicate that the LCD panel is faulty, rather than the cable itself.
Before attempting a display panel replacement, you may be able to resolve the issue using Lenovo’s troubleshooting guide.
Make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
