Mac Hosehead Posted November 30, 2015 Share Posted November 30, 2015 This vintage MBP was notorious for the nVidia chip failing. Here is a site where some people have got it working using various methods. Of course, YMMV. https://www.ifixit.com/Answers/View/9045/MBP+A1226+Logic+Board+last+resort+fix+for+nVidia+video+chip -MH Link to comment https://www.insanelymac.com/forum/topic/309644-mbp-15-2008-powers-on-but-no-display-or-input/#findComment-2193011 Share on other sites More sharing options...

Mac Hosehead Posted November 30, 2015 Share Posted November 30, 2015 Unfortunately, it is a chip and not a card. Someone from that link does actually change the chip but it looks like he had professional equipment. Apple was replacing motherboards under warranty for a while. I did see this happen to one of these and I can't remember if the keyboard worked but I don't think it booted. -MH Link to comment https://www.insanelymac.com/forum/topic/309644-mbp-15-2008-powers-on-but-no-display-or-input/#findComment-2193062 Share on other sites More sharing options...
