No backlight after LCD replacement
Hi all, after a lot of work I replaced the LCD of my Macbook Pro 13 but when powering it back on there is no backlight on the LCD. I can just about see the display so I know the LCD is ok.
I have checked the small connector is securely connected to the LCD board and the LCD cable is securely fastened at both ends.
What could I have missed? Is the backlight separate from the LCD?
Thanks

A bit more reading and it looks like it could be a backlight fuse issue. Does anyone know where it is on this model and how to test it? It could be the backlight itself but I don't want to remove the LCD unless I am sure because there is a high chance it may break in the process and it wasn't cheap!

It ended up being an incompatible part number. My original display was LSN133DL01 and the replacement was LSN133DL02. When trying another known good LSN133DL02 the backlight still didn't illuminate but when replacing the entire top assembly (containing a LSN133DL01 panel) it worked. I know the LED backlight was working as when I used the original LSN133DL01 board on the original top assembly the backlight illuminated. Very weird but finally resolved.
