I have an Early-2008 Apple MacBook Pro pre-Unibody that boots to a blackscreen (no video signal). My troubleshooting and research has revealed that these laptops have a history of a defective nVidia GeForce 8600M GT video chipset (G84-602-A2) and that a revised version was released in 2010 ($30 part).
Anyone at DMS interested/able to perform this type of repair involving replacing a GPU on a logic board? Or know someone who who might be? Happy to pay someone! I would rather find someone local to repair this rather then send it across the country.
I found this video below demonstrating the repair https://youtu.be/jSYriWF_2Qs
