A while back, user "raybay" posted some guidance on replacing the backlight and/or inverter on an ibm thinkpad r51 notebook. Here is a quote: Inverter. That is a very high price for an inverter for an R51, but the R51 is a very rare computer... so you may have to pay it. you need a very good quality #1 hard steel philips screw driver, great care in removing and replacing the screw covers, and the time it takes to remove and replace 18 screws. But the inverter just plugs in. Mark all your screws as you remove them as they are not all the same length or diameter. But the most important function is removing the screw hole covers so you can use them again. You will benefit from a very, very thin flat blade screw driver or other tool to lift the screw covers out and off. You will need a nice adhesive that remains soft when you replace them. It is very rare for an inverter to go out in that model. What I'm wondering is, this sounds like instructions for replacing just the inverter, but what if my problem is with my backlight as well (or instead)? Apparently they can also be replaced, but I've read suggestions that this may involve soldering. If you are lurking, raybay, do you know specifically what is required to replace the backlight on this model?
