Logic board replacement - From 2.5 to 2.4

I just had my Logic board die (ie. display) Turns out Apple has extended a "Quality" program for this model (the 2.4GHz board/A1226). Check with apple first...''

logic board seems dead i.e. steady mag safe light on disk spinning , black (dead ) screen ,pram won't reset , power management wont reset either . Vidia chip has a bad connection ! it needs heating up to reflow the pins connecting it to the logic board . check posts on this subject . It is a bit of a long shot but IT CAN BE FIXED (i have managed to do it ). i also let it heat up and soak tested it for 24 hrs after the baking trick ,blow torch (small iroda 50-70 watt Maplins )+clamping it down when as hot as possible. the only question is reliability !!It has lasted 3 months so far, and that is being thrashed non stop until red hot over and over again . It is still a bit of a guessing game (not like the old days of soldering a cct board with a dry joint ) with no cct or wiring diagrams . i would like to know the details of the electrical connections as in many cases of a 'dry joint' if you are not a 100% sure of which pin/connector that has caused the problem , one cannot be sure its fixed as it might be a case of just touching the right point and not soldered properly then breaks down when you are doing a presentation or working in a tight spot under pressure. i suggest you do all the styles available on ifixit (top site). cover in a quilt and flip over with the supply connected until red hot ! then leave it to cool down , reset power management (hold down power button with batt removed for 10sec +)and reset pram (hold down power button with batt fully charged until mag safe light flashes) you will hear a tone . the screen will light up .then the usual disk utility repair (permissions etc ) and its up to time to see if it lasts . If not repeat the procedure and it will finally hold out (mine has for 3months so far ).good luck it will work !
