Screen Backlight Not Working!
My MacBook Aluminium Mid 2008 is not working.
I've already change the LVDS cable and the display screen.
The common things to do like press the cmd, option and P and R keys when booting don't work.
I don't know what to do, I've seen a lot of people having the same problem but all of them have MacBooks where you can change the inverter board, I think that in my case this is not possible.
I do not have the HDD installed (crashed), the Desktop is not visible even with a flashlight, the start up sound "tadaaa" is sounding normaly after I press the power button and that is it...
The LCD screen is changing (more darker) and nothing else, the cpu fan is operating.
p.s. My macbook is a 2.4GHz intel core 2 duo mid 2008, just MacBook aluminium (A1278), not the Pro version
The last four digits of my serial number are 5W7A
THANK YOU !
