or you could send me the logic board, and i could run it on the IR reflow station and see where that goes. thats how i fixed my imac g5 17". Only thing though is your in Australia so shipping could be a problem.

grab some chipquik SMD291 flux, go around the IC. before preheating.

Really all you need is a pancake griddle setup to about 400deg.

Let it preheat. Then you reflow it with a heatgun. use a cheap thermocouple meter and slowly heat the chip up to 212deg C. then let it all cool down. that should take care of it. Make sure you clamp the board though so it cannot warp during reflow. itll strengthen itself out that way during preheating. Because if it warps during reflow, itll cause bridges around the edge of the IC
