I had A1226 recently went blank screen with lid led light turned on. I tried blanket method several times but didn't work. So finally, I disassembled logic board and wrapped with foil, exposed GPU and used hair dryer for about 3mins. After natural cooling, the screen showed up and it works nicely. Thanks for sharing this post.
Definitely I visited Apple Store here and the technician told me it would cost several hundreds to replace the logic board and recommended buy new one. But now I am happy with my Macbook Pro back to life : )

Now I am also using smccontrol app to run the fan faster and keep the heatsink cooler.
Another success story here.
