    I have a mid 2008 macbook pro with a 8600m gt video card. It always had problems with occasional scrambled video, but always went away after a restart. Lately it was happening more frequently until it finally died. Now there is no display or external video. It won't boot. When I press the power button the indicator light turns on and the fans start but the display is off and the hard drive doesn't boot. I did some research online and found out that Apple is offering free repairs for this problem I took it to the Apple store and they tried plugging a firewire device into it. They said they couldn't connect to the laptop so they can't get a code and fix it for free. They said the logic board needed replacement. They said most likely the video card is defective but they can't do the recall without the code. I called the Apple 800 number and asked if there was a specialist shop that could do a more thorough diagnostic on my laptop so I could qualify for the repair. They sent me to a specialist shop who was unable to get the code.

    My question is, could my laptop have these symptoms with a failed video card (no boot, no display) or is the motherboard itself dead? My Dell desktop had similar symptoms when I first got it, but Dell sent me a new video card which fixed the problem. Is it worth pursuing the recall repair or is something else wrong? Apple said they can repair the logic board for $330. The specialist shop said they were wrong and will change their price midway through the repair and it would probably cost $1000+ to repair.

    A friend of mine told me about a oven trick that could work. He put a damaged Nvidia video card in the oven for a few minutes and it fixed it. I read a couple of success stories of this method on a macbook pro. It seems like it wouldn't be a bad idea if a new logic board will cost $1,000 plus.

    I gather you don't have Apple Care? The GPU is soldered onto the logic board (= motherboard), so either way, Apple has to replace the logic board anyway. But if the defect is not the GPU and you don't have Apple Care, you're out of luck.
