Lenovo DOES NOT sell backlights. There is no FRU for a backlight, nor there ever was one.
These were not meant to be user replaceable.

Get the right parts... there are two and usually run for less than $25 on eBay. But be certain you get new ones, and not used ones. They are $75 or so from the set at Lenovo. The trick is the cosmetics... making it look good... And to have a workbench for the removal process where you wont be disturbed if you have to quit and startup again the next day. Take off the keyboard, and remove the cable from the base to the screen assembly. There are 18 to 24 screws to remove of various small sizes. Most are covered with rubberized screw covers that make them nearly impossible to find and remove unless you are patient. There are different sizes so map them as you go... just draw a simple location map. Use some soft of tweezers and a sharp tool to remove the screw covers without damaging them. Some compound found in hardware stores called De-Solve-It along with some denatured alcohol will be useful... if no De-Solve-It is available where you are, use a similar oil based compound to remove the sticky rubber cement. Once you get all the screws out, the screen easily comes apart. You unplug the bad inverter and bad backlight, and plug in new ones. Next is the simple job of reassembly. Once done with all the screws, test a couple of hours to make sure it works, and looks great. Once comfortable that you have success, begin the slow job of replacing the screw covers with a razor blade or other sharp tool... using your favorite rubber cement. My first one on a Thinkpad took two hours. Now I can do them in a half hour to 45 minutes... and they get prettier each time. You can also buy screw covers on eBay, but a prefer making my own out of very thin sheets of rubberized material. You will need to experiment. You will find you need to experiment with the screw cover material until you get it right, so don't plan on doing the first job quickly. You are guaranteed to make a few mistakes. You can also use a tube of rubberized cement material but it doesn't look as good when i do it. Once you get good, you can get rich doing them. RayBay - - - - - Life is tough.
