No screen backlight, seems an inverter problem

Hi there,

I'm Maria Aurora from Italy, I'm having some trouble with the my Macbook.

I can see the image on the screen only by pointing a flash light to it. The backlight of the LED panel seems gone.

I've heard about an inverter, and I hope I can fix it easily, but I cannot find nothing about in the store for my model. Someone can help me finding it and with a step by step guide to replace it?

Many thanks

This model uses a driver chip Vs an inverter as you are powering LED's Vs CFL's.

To start with I would first check the fuse link as it may have blown.

Here's a link to the full logic board and a magnified image of both the fuse and the driver chip locations.
