I have Lenovo T460s with Intel i7 6600u and wQHD LCD 2560x1440. There is some short on mainboard and LCD will not turn on. External HDMI monitor works. I tried repair service and they did not fix it.
After 2years I found this repair video, so I disassembled my notebook and checked all fuses on mainboard with probe and microscope.
I found broken fuse F3 near 60pin flex cable on mainboard. I disassembled old Acer notebook, where I found this small 1x0.5mm fuse and resolder it to my Lenovo T460s notebook.
It has been surgical work! I lost 2 times this tinny little Fuse. But finally I got it!
HOW TO TEST?
I have another Lenovo, but is T470s next generation with USB-C. I hoped, that LCD could be swapped between those two notebooks (but it has only full HD resolution 1980x1020). So I disconnected 60pin LCD Flex cable from T470s and connected it to repaired T460s and powered it on.
And voila! It works!@@@@
