Power failure to logic board
Hi, i recently bought a second hand MacBook Pro a1260 and i used it for only a few hours before it started failing to boot. Black screen fans and disk spinning but nothing else. I took out the logic board and the CPUs were not clean or pasted properly so i cleaned them up and put new thermal paste on and i got several more hours of boot time. Today it died again and I have isolated the problem to a bad connection on the ic chip to the right of the memory (f2116bg20v h8s) it looks like this processor has a weak connection if i lift the rhs of the chip the system boots fine. Is there anyway i can fix this or does this mean a new logic board? Last digits of serial number are z3ja

Thanks guys for your help. I will look into getting it repaired one way or another.. Just for reference dan :) "he" is a "she" :)
OT would a hot air gun help reflow the chip or does it need to be completely reballed?

S3r3n31, thank you for accepting my answer. You could try a reflow with a hot air gun. Really, nothing to lose at this point. Just make sure that you shield all the other nearby components from the heat. There are a couple of good youtube videos, something like this, that may help you. Just remember the objective is to soften the solder, not to liquify it:-) Best of luck to you.
