Why isn't my backlight on?
MacBook Pro 15 22 Unibody 2.53 GHz Mid 2009
I have a mid 2009 15" Macbook Pro 2.4 Ghz Intel Core 2 Duo. the computer boots up. There is a chime and the screen boots up. But no backlight. So the only way I can see my screen is by holding a flashlight to it. I know the computer works. I plugged it up to an external display and it worked fine. I know it's not software because I booted from an external HDD which I know works.
I read on another forum that these models use LEDs and don't have an inverter.
So my question is: What makes the backlight work? What do I have to replace to make this screen visible?
Any general info about the screens or inverters or whatever is helpful. Thanks
Is this a good question?
