Hello all, I have a A1260 2.6, that will not boot, (1) No startup sound (2) Solid power light (not flashing) (3) fans spins Tried PRAM and SMC/PMU reset didn't work. Bought a used MB and replaced it same issue as above, seller took the board back but did state it worked when he took it out of another pro. Then I bought another mb bottom case (used but working per the seller) same model a1260 (but 2.5) this is complete bottom case minus the HD, memory and CD drive. Same issues as above no change, tried all the fixes as well. This leaves me to believe it's not the logic board. I disconnected HD, topcase (shorted on using pins to start), CD drive, display, same issue as above. I tried the memory one stick at a time in different slots. When there is no memory I get the error beep. Question can the power charger be bad, even though I get a green light? Also I have a battery that is good, it wont start with that either. It looks to be taking a charge with the power adapter... Can a bad display prevent it from booting? Can both memory sticks be bad, what are the odds of that? HD, memory, CD etc all worked up to one day...then it was just off. Why on earth wont this boot up, is this another bad logic board? I feel that everything has been swapped at one point or another. Thoughts? thanks for reading.
