backlight not working after liquid spill
I have a macbook that works fine after a liquid spill except the backlight does not turn on anymore. There was some residue on the logic board so I presume something related to the power circuitry has short circuited or a fuse has been blown. I checked the screen cable and it is fine.
So my questions:
1) How likely is it that replacing the logic board would solve the problem? Could the backlight itself be broken and how to test this?
2) Does anyone know which part of the logic board is responsible for the backlight power? In that way I could check the components to see if they are broken or not and possibly replace them.
I did not find the fried component. The laptop is sold by now, for a very low price :-(
I was able to find a drawing of a previous generation macbook that allowed one to search for the component's location. I guess it is only a matter of time before such a drawing also comes available for this generation....
Es esta una buena pregunta?
