Backlight always ON after changing the inverter even if the mac is off


Backlight on the screen was not working, so I change the inverter from a A1226.

Now, if I just put the battery, my screen is lightning even if the computer is off, and when I put it on, it works fine except the luminosity levels on the keyboard.

My screen is a glossy one and I took the inverter from a matte screen. I also change the cable.

Any solutions ?

fab.breek this is usually caused by an inverter issue. You said that you "so I change the inverter from a A1226." but did not tell us what exact model your computer is. In your case it is entirely possible that you have a wrong/different internal wiring inverter. Replace it with a proper model inverter and let us know what happened.

My computer is a A1226, is it possible to rewire the inverter ?


Most likely not and you definitely would not want to go down a Rabbit hole. I'd opt for just getting a proper one.


ok, i'm gonna try to find an other one, thanks ! i'll keep you informed
