Step 34
Disconnect the modem from the logic board by lifting the bottom edge of the modem. Don't remove the modem entirely just yet as it is still connected to the RJ-11 board.
Step 35
Turn the modem over and disconnect the RJ-11 cable.
Step 36
The connectors at the ends of the cables are often attached very firmly to the sockets on the logic board. Pulling directly on the cable will either separate the cable from its connector or the socket from the logic board.
Carefully disconnect six indicated connectors from the logic board. To disconnect the four white connectors, use your fingernails or a dental pick to carefully pry the connectors from their sockets. Make sure you're pulling only on the connector and not on the socket.
