My MacBook Pro 2.4 Ghz don't have sound, Airpor, Usb, screen black
My Laptop, do not appear to have any port available on the left side, only the power port work, and my screen goes black but it's work, if you look careful on the screen you can see that it work but of course with no light... all others functions appears to work fine, even the DVI port for additional display works fine...
This issue have relation with the envidia problem? or just be the left i/o board? I live in Venezuela, and I wish to know what I need to put my laptop to work again...
To access the hard drive put it into Target Mode by hooking up to another Mac via a firewire cable and start holding the "T" key down. You hard drive icon will show up on the other macs monitor. If you can see the screen with a flashlight held at an angle the inverter is out.
Here's the inverter: MacBook Pro 15" (Models A1226/A1260) LED Driver Board

Besides replacing the inverter, I would also replace the left I/O board. Here's the part: MacBook Pro 15" (Model A1260) Left I/O Board

Includes MagSafe power, USB, and audio ports — 10 available at 119.95 each.
LED Driver Board controls the LED backlight. — 1 available at 44.95 each.
Shine flashlight into the front of LCD. If an image is being displayed. GPU (Nvidia) is fine cause image is present but backlight is not ON. Check logic board connections.
You also said external display works fine via mini-DVI port. So Logic board and Nvidia is fine.
Reseat and check that the display connections to the logic board are secure. If it is still the same I would suspect display assembly.
If still the same after display then poor or no backlight LED Driver power, faulty logic board.
