Welcome to the Apple Support Communities
From what you say, the display or the graphic card is damaged. It looks like it could be the graphic card, because the display usually shows geometric patterns when the graphic card is damaged. The only thing you can do is to take the MacBook Pro to an Apple Store or reseller. The logic board has to be replaced, so it will be expensive
I just went in yesterday to genius bar because my 2008 17" Macbook Pro would turn on but have a black screen. No video and they tried resetting it hooking up external monitor and nothing. They said it was the logic board. They quoted me $600 in store or $310 sending it out. I went with the cheaper option and just left my laptop with them yesterday. Hope this helps:)
Thanks for your quick response.
I suspect you may be right about the video card.
Does anyone have any idea of the approximate cost (USD) of replacing the video card / logic board?
In the MacBook, everything is soldered into the logic board except the hard drive and the memory. A logic board replacement may cost half of the price of the computer
Thanks again!
You are welcome
