Use this guide to replace the LCD cable in your Lenovo ThinkPad T460 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.

Thanks so much for this, Kristen. I managed to fix my T460 by replacing the LCD cable using this guide.
The symptoms were quite odd: the slightest movement of the laptop hinge (even a touch, sometimes) would cause the screen to go blank and the laptop to go into hibernation. I could get it back out again using the normal method (pressing the power button), but it was happening all the time. I guessed that it was the wiring of the LCD cable causing this, so I replaced it with a branded Lenovo replacement and now it works fine.
