    Hello All,

    I have been having a very troubling problem that began about 1 week ago. My MacBook Pro (2.2 GHz Core 2 Duo, bought July 2007) has been experiencing issues where the power button is pushed and it appears to turn on, but the screen remains black (not even the backlight comes on). However, I suspected the actual operating system was running nominally, as I could get iTunes to play music just fine (using key commands). After this problem arose, I brought to an Apple Store where they quickly turned me away due to the physical state of my laptop (there are many dents and scratches). The genius who helped immediately told me the problem was from physical abuse to the computer, but didn't offer any insight as to what was actually wrong with it. That night, I called Apple Care and spoke with a representative. The woman said it may be a software issue and had me run some diagnostic tests using the keyboard, but to no avail. The next day, I brought the computer to an Apple Authorized Retailer, where they disassembled it. After, they told me they suspected that the LCD was cracked internally. After hearing the repair price, I was prompted to buy a new iMac, which I am using now. When I connected the two computers with Firewire to transfer data and booted my laptop in target mode, low and behold the screen worked and the Firewire symbol appeared. Upon restarting the computer, the screen once again failed to work. I have made many attempts at restarting it after this, but still no luck.

    Does anyone have any idea what could be wrong?


    (PS: Thanks for reading all that, if you did.)

    Did you already tried to connect a screen to your MBP? if the screen works you screen is broken if not then it's your GPU!!!

    Recently I had the same problem. When pressed the power button I could hear the boot sound and later the typical skype login sound. The only problem I had was I couldn't see anything. Screen completely black, nothing.

    I also went to an AASP and there they told me the GPU had failed and the whole logicboard had to be replaced and worst of all it would cost me about $1100.00 since I don't have any warranty or Applecare. Their advice was to get it fixed or to buy a new mac. They also recommended to call Apple because i bought the mac online at Apple. So I called and they told me the same.

    Because I couldn't accept to throw my MBP at the garbage just like that I did some research. and I found this:

    On this forum there are some more threads about this matter, and as you can see you are not alone...

    After reading all this I went back to the AASP and confronted them with all this. My MBP showed the same "symptoms" and further it fits the description. I also explained them I wouldn't accept a no as an answer. I had to wait for what Apple would say and it might take a while.
    But after one week I was called with some good news. The logic board was replaced under warranty! You understand I was relieved and very happy with the result...

    So there might be hope for you... Goodluck!!!

    Thanks for the help, those links were really helpful!

    I have plugged it in to an external monitor, and nothing happened. I think I'd have to go into system preferences on the computer and set it to mirror its screen onto the external one. But I can't do that, unless there is some key command for changing that setting. Do you know of one? I couldn't find anything online.

    If that doesn't work, this faulty Nvidia graphics issue may be the culprit. Funny how I haven't even heard about that until now.
