I bought a used iMac with Win XP, via Boot Camp; I wanted a dual-boot system, for weaning an office worker off Win toward Mac...
I bought the part, I took the MBP apart, I changed the inverter, I re-assembled, I powered-up, and it worked! There are several tiny connectors to undo and redo, and many tiny screws to keep track of. It took about two hours on a rainy day, when I couldn't work outside anyway. My second iFixit project, and success both times! Thanks.
