    • Tilt the top edge of the board away from the rear case and lift the logic board assembly out of the rear case, minding any cables that may get caught.

    • When reinstalling the logic board, it is helpful to use tape to temporarily tuck the cables out of the way until the board is properly seated in the rear case.

    • During reassembly of the logic board, pay attention to the position of the I/O connectors. When the board is back in the case, insert a USB or Thunderbolt cable into one of the connectors to align it perfectly.

HI hello, I´m having some problems with this iMac; can someone help me, please. I change the hard drive for a SSD, The problem is there isn´t a startup sound and also no video signal shows, when I turn on, everything is perfect, the 3 fans start running, but thats all.

I´m trying to find the possible damage part with no success.

Could be the motherboard?

Where I can buy it?

Thank you very much and excellents manuals, I always look here.
