Fuse map of W540 needed

[Jackbee]

I experienced that same backlight fuse issue that I got with many other people swapping out LCD panels while the battery was still inserted. In addition, the broken screen that was supposed to be swapped out also stopped working, so I attempted to test my T540p panel. Of course, it worked but the the backlight did not, as I expected. I could still see a picture with a flashlight.

But what was even dastardlier was that after 5 hours of leaving the W540 on, in the stupid hopes that the fuse would somehow come back to life, not only was it still burnt out, but the panel also stopped showing a picture! This time, a flashlight showed nothing. Was another fuse blown? I'm not sure myself, and that's why I've come here for consultation from anyone who can read schematics.

The W540 still works in particular with an external monitor, and swapping the panel back into the T540p resulted in a working, backlit picture. So no, the issue is not that the T540p panel itself stopped working, and it's not that the W540 stopped working, either.
