iMac Intel 21.5" EMC 2544 Display Replacement

Giriş

Removing the display on the Late 2012 iMac requires cutting adhesive with a specialized iMac opening tool. After you've completed your repair, you'll need to follow our Adhesive Strip Guide to scrape off the old adhesive and replace it with new double-stick adhesive strips.

    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed as shown, but are faster and easier with an iMac service wedge.

    • If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.

    • Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

    • 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.

    • 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 enclosure.

    • 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. Otherwise, you risk severing antenna cables and causing serious damage.

    • Be gentle! The glass may crack if pried too much. Use a hairdryer to heat the edges and loosen the tape if the room temperatures are low.

    • 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.

    • While the opening tool cut most of the adhesive, 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, wedge a plastic card between the display and frame.

    • Be careful not to insert the plastic card more than 3/8", or you may damage internal components.

    • Gently twist the plastic card sideways to create a gap 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".

    • Gently twist the card upward, slightly increasing the space between the display and frame.

    • As with the other side, twist slowly to allow the adhesive time to separate, and be careful not to over-stress the display glass.

    • With both plastic cards inserted as shown near the corners, gently twist the cards sideways 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 remaining adhesive.

    • Begin to lift the top of the display up from the frame.

    • Only lift the display a few inches—the display data and power cables are still connected to the logic board.

    • While holding the display up with one hand, use the other hand to unplug the display power cable. Make sure that you pull the cable out from the plastic tab, and not by pulling on the color wires.

    • Lift the display up enough to have easy access to the connector, but not so much that you stretch the cables and stress their connections (about 8").

    • Use the tip of a spudger to flip up the metal retaining bracket on the display data cable.

    • Carefully pull the display data cable from its socket on the logic board.

    • Be sure to pull the display data cable connector straight out of its socket.

    • 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.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).

    • Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.

    • Repeat this step with the other adhesive strip and remove it.

    • If either adhesive strip breaks before it's removed, use a plastic card to slice through the remaining adhesive.

    • 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.

    • Be very careful handling the display—it's big, heavy, and made of glass.

    • During reassembly, head over to our display adhesive guide to install the new adhesive.

It was really easy but the display did not power on for me. Any suggestions?

Edward Bennett - Yanıt

I got to the point where I fit in the display back on before I pulled the covers off of the adhesive strips. I turned the computer on and the display worked perfectly. Everything worked! The camera was aligned and everything! It must’ve been beginners luck.

I turn the computer off, unplugged the display, pulled the covers off the adhesive strips, plugged the display back in and sealed the display down. When I turn the computer on again I had a blank screen. It wasn’t just blank, it never came back on. The iMac did, but the display didn’t. I tried the old display. Same thing. After some research I found that I had burned up a device on my logic board.

So, I am left with only my iPhone and don’t know how to upload a picture in comments or I would show you exactly which one it is.
