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.
Some suggestions?

p.s. My macbook is a 2.4GHz intel core 2 duo mid 2008, just MacBook aluminium (A1278), not the Pro version
Thank's
The last four digits of my serial number are 5W7A
THANK YOU !
Esta é uma boa pergunta?
Does this http://www.everymac.com/systems/apple/ma... look like your model? Your serial number does not give me a match.Why did you change the LCD and what is the model number on your LCD? Any number will help to properly identify your hardware

Well yes & no ;-} The need for a bootable disk (one with the correct OS for you system) allows us to see if there is a desktop image (even with no backlight) without the disk you should only see a smaller blinking question mark on the screen (smack in the middle). Try shining a flashlight from the lids Apple logo inwards (a poor mans backlight as we call it) to see if you see the question mark on the screen. What gets me here is you do see the phasing of the liquid crystals (screen gets darker) so we know the display is working to a point.
