I have a 17" Macbook Pro which stopped working a while ago (out of warranty). When you turn it on, the light at the front would go on and thats it, nothing on the screen no start up chime. Took it to Apple and they said the Logic board was gone and it would cost $600 to replace. Sad day.
Then I saw the follwoing video which said the problem with Logic Boards occurs mainly due to micro fractures in the solder on the chips . The solution they showed was bordering on me believing it was an April Fools joke. Basivcally they removed the Logic board then placed it in an oven at 200 Degrees Celius for 7.5 minutes.
Since there was nothing to lose , I gave it a go. After a lot of fiddly work getting the thing opened (worse getting the motherboard connections back on). I got the board out and put it in the oven for 7.5 minutes at 200 degress celcius as the video said. I also put a bit of solder next to it to see visually when the solder melted. . Let it all cool down then cleaned all the heat sink contacts and applied some new thermal paste to the chips. Put it all back together which was a real hassle. Turned it on and..... It Works.
Anyway, if you are having the same issue here are the repair videos I mentioned:

If you attempt the fix , make sure you do the following:
1) Pre heat the Oven properly
2) Clean the fans out and ensure the vents are clear and the fans spin
3) Clean the old thermal Paste off the chips and the heating pipe and reapply new thermal paste to the chips before putting the logic board back in. Use rubbing alcohol to clean the old paste from the chips etc.
4) Try to prop the bard up with foil in places it doesnt touch any chips etc
5) Don't touch the board until it cools down. If you touch it to early the solder will still be fluid and you displace components.
6) Don't forget to ensure all connectors are back on the board when you put it back in. Some are heat sensors
