Ada sekitar 54 Langkah Cara Mengganti Kabel SATA Pada iMac Intel 27″ Retina 5k Display.
Yuk kita cermati setiap langkah-langkahnya :
Step 1 — Display
Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear case.
The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8″ into the display. You risk severing antenna cables and causing serious damage.
Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.
Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle.
Run the tool up along the left side of the display.
Continue wheeling the tool up around the top left corner.
Cut the adhesive along the top left of the display.
Continue along the top of the display.
You may want to run the tool back and forth through what you’ve already cut a few times, to ensure you get as much of the adhesive separated as possible.
Push the tool around the top right corner of the display.
Wheel the tool down along the right side of the display.
Finish pushing the opening tool to the bottom of the right side of the display.
At this point, you’ll want to run the tool back around the entire display, to ensure you cut as much adhesive as possible.
While the opening tool did the lion’s share of the work, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive.
Set the iMac face-up on a table.
Starting from the top right corner of the iMac, insert a plastic card between the display and frame.
Be careful not to insert it more than 3/8″, or you may damage internal components.
Gently twist the plastic card to open the space between the display and frame.
Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4″.
Be sure to stop cutting before the iSight camera in this step, or you may damage it.
Slide the card toward the center of the display, to cut any remaining adhesive.
Put the card into the corner again and let it stay there to keep the adhesive from resettling.
Insert a second card into the gap between the display and frame in the top left corner.
Gently twist the card, slightly increasing the space between the display and frame.
As with the other side, move slowly to allow the adhesive to break, and be careful not to over-stress the display glass.
Slide the plastic card toward the center, again stopping just before the iSight camera.
Insert the card back into the top left corner.
Only lift the display a few inches—it is still attached to the iMac by data and power cables.
With the cards inserted as shown near the corners, gently twist the cards to increase the gap between display and case.
If there are any sections that seem to stick and won’t separate, stop twisting and use one of the cards to cut the adhesive in the problem area.
Begin to lift the top of the display up from the frame.
While holding the display up with one hand, use the other to unplug the display power cable.
Lift the display up enough to have easy access to the connections, but not so much that you stretch the cables and stress their connections (about 8″).
Flip up the metal retaining bracket on the display data cable.
Disconnect the display data cable.
This is a delicate connection that can easily be broken. Be sure to pull the display data cable connector straight out of its socket, toward the top of the iMac.
Lift the display up to a near-vertical position.
At this point there is still a strip of adhesive along the bottom of the display, that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.
If necessary, a plastic card can be used to cut any remaining sections of the bottom adhesive strip.
Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).
Be very careful handling the display—it’s big, heavy, and made of glass.
Lift the display up from the frame and remove it from the iMac.
It may be necessary to slowly lift from one side, to peel against the remaining adhesive.
With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed with the iMac laying down, but are faster and easier with an iMac service wedge.
Step 24 — Left Speaker
Remove two 10.0 mm T10 screws.
Unplug the left speaker cable from its socket on the logic board. Be sure to pull straight up out of the socket.
De-route the cable from the gap between the hard drive and logic board.
If the gap between the hard drive and logic board is too narrow for the speaker cable, disconnect it and leave the cable in place.
Be careful not to touch any solder joints on the back of the power supply. Capacitors may be charged enough to give you a dangerous shock.
Use a spudger to disconnect the power button connector from its socket on the logic board.
Lift the left speaker straight up, until the power button cable is exposed (about 0.5″).
Gently de-route the power button cable from its groove in the left speaker.
Lift the left speaker straight up and remove it from the iMac.
If the gap between the hard drive and logic board was too narrow to free the speaker cable earlier, gently pull it free as you remove the speaker.
Push from the connector end as you pull from the speaker end to thread the cable under the hard drive’s right bracket.
Step 30 — Hard Drive
Pull straight up on the SATA data/power cable to disconnect it from the drive.
Remove two 7.3 mm T10 screws securing the left hard drive bracket to the rear case.
Grab the hard drive and left hard drive bracket together.
Tilt the left side up away from the rear case, and slide the assembly to the left.
Remove the hard drive and left hard drive bracket from the iMac.
Remove the left hard drive bracket.
Step 34 — Power Supply
When working on the power supply, be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.
Disconnect the power supply control cable from the power supply.
Remove the following four screws securing the power supply to the rear case:
Two 23.7 mm T10 screws.
Two 7.3 mm T10 screws.
Do not attempt to remove the power supply from the case; it is still attached to the logic board by two cables.
Move the power supply board towards the left edge of the case and up to free it from the notch in the logic board.
Pull the DC power cable straight out of its socket on the back of the logic board.
Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.
Flip the top of the power supply towards you, like opening a mailbox, to reveal the AC inlet cable connector.
Disconnect the AC inlet cable connector.
Step 39 — Right Speaker
Remove two 10.0 mm T10 screws.
Gently rock the right speaker slightly to the right, to allow access to its cable’s connection on the logic board.
Use a spudger to loosen the right speaker cable’s connector from its socket on the logic board.
Pull the connector to the right to remove it from its socket.
Lift the speaker straight up and remove it from the iMac.
Step 43 — Fan
Use the tip of a spudger to disconnect the fan cable’s connector from its socket on the logic board.
Peel the black tape connecting the fan to the exhaust duct back slightly.
Leave the tape in place on the exhaust duct, you only need to expose the joint to free the fan.
Remove three 12.4 mm T10 screws securing the fan to the rear case.
Remove the fan from the iMac.
Step 47 — Logic Board Assembly
Use the flat end of a spudger to disconnect each of the four antenna connectors from the AirPort/Bluetooth card.
Note the original positions for each connector when reconnecting the cables. From left to right on the card, the antennas are connected in the following order:
This is a delicate connection that can be easily broken.
Flip up the metal retaining bracket on the iSight camera cable.
Pull the camera cable connector straight out of its socket, toward the top of the iMac.
Use the flat end of a spudger to disconnect the headphone jack cable connector from its socket on the logic board.
Gently push the cable out of the way.
Remove the following screws from the front of the logic board:
Two 23.7 mm T10 screws.
Four 7.4 mm T10 screws.
One 20.8 mm T25 spacer screw.
One captive T10 screw.
This screw is beneath a hole in the logic board. You’ll need a fixed screwdriver or the 60 mm extension from an iFixit driver kit to reach it.
The hard drive SATA cable can’t be removed just yet, but will get in the way of removing the logic board.
Pull the cable and connector through the right hard drive bracket. Move the cable to the right side of the iMac, out of the way of the exhaust port.
Remove two 5.7 mm T10 screws from the top of the heat sink exhaust duct.
Tilt the logic board slightly forward.
Lift the logic board straight up and out of the iMac. Be careful not to snag on any of the screw posts attached to the inside of the rear case.
Step 54 — SATA Cable
Pull up on the SATA power cable connector to disconnect it.
Unplug the SATA data cable connector by lifting it up.
Remove the SATA cable from the logic board assembly to get it out of the way and prevent it from being damaged.
