Introduction

Removing the display 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.

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. The hub on the iMac Opening Tool will keep you from pushing the wheel in too far.

Would a heat gun make this step easier? Or damage the iMac?

A heat gun wouldn’t help you here as you still need to cut though the adhesive. You also risk damaging the display with the excessive heat.

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.

I found the 'pizza cutter' surprisingly smooth at cutting through four-year-old adhesive.

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.

Deck the Halls
With tools and Fix Kits
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.

I actually DESTROYED my display (black vertical strips) by pushing the card in a bit TOO DEEP. So it is REALLY important to insert the card only a bit (1-2mm) more than the cutter wheel, in particular at the top side, where many flat cables connect the panel with the PCB. These can be damaged very easily!

Same thing with me…. Pushed cards to far…. new panel needed…€600…..

i think ifixit needs to place a bigger caveat, as I have missed it the first time

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".

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.

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").

Mark all cable connectors with a spot of white correction fluid before removal. This will remove the risk, when reinserting them later, of getting them the wrong way round. Yes - I know they will only plug in one way round, but it does make life easier if you are not in perfect lighting!

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.

I replaced HDD to SSD and assembled parts again. When I boot up the iMac, I found black lines on display (looks partly not broken).

I searched Internet, and some says graphic card problem, but I didn't touch anything but cable to lift up.

Could the damaged display data cable cause this situation? I hope I could fix this by just replacing the cables..

Sorry, Black lines is a damaged display assembly ;-{ In the process of removing it you either pushed the tool into deep or you torqued the glass severing the tiny wire traces.

Same trouble here, is it cable trouble or connector trouble?

I think whenever words like "...is a delicate connection that can be broken. Be sure to pull the [cable in a certain direction] ANYTIME.... It is worth either a closeup or 2, maybe one with annotations or insertion directions and maybe a motion direction arrow with the something like and 'X' char or a circle division slash over the wrong one.

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.

Thank you Stef, that's what i will do next time, i cracked the lower part of the screen went opening very slowly, that's probably why those "tabs are for !!

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).

Would have been helpful to box the same red area when using the plastic card to separate the glue. Since the red blocked picture is inverted, if someone doesn't pay close attention it may not be obvious that the area of concern is at the right top of the graphic pictures in which the plastic card use is being demonstrated..

you don't need to cut the bottom part as the bottom tape is stuck on each side and you can easily pull it out

Thomas Webb - Reply

What is the twisted wire taped to the back of the display that can bee seen in the upper right of the first two pictures? I have an 27” iMac without a screen an my replacement does not have this wire. I think it is a temperature sensor but do not know where it connects to.

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.

I'd like to note, that it is in no way necessary to save the wedge for when the screen is removed. In fact, the wedge is used when removing the LCD, because the rear housing may tilt when removing it, and the wedge counters this.

So, for your own sake, DO NOT lay down the iMac, but in stead, leave it standing upright, with the wedge in place, when removing the display, and let it stay there until you're done with servicing your iMac.

Also, from step 18 through 22, the iMac needs to be standing upright, NOT lying down, as you can easily damage the glass when lifting it like that.

Since there is not antenna wire to cut around the frame, I used a razor blade and and stopped at the camera and it worked like a charm. Where the guide used the card on the bottom edge for the final cut, I used a razor blade also and it only took one cut verses going back and forth with a card.

When I used a tool, the adhesive kept sticking together again as the guide mentions. The razor cut the adhesive down the center itself, so it was one easy pass and on sticky adhesive.

If you take a small chip out of the glass on the edge or crack, just get cell phone protector and cut it to size. You can also go to home depot and they have a glass specific crazy glue that you can first put in the crack or chip (do not put on the casing part. I cleaned with crazy glue first). Use a razor to get the glue into the crack, let dry and then clean off and put on the screen protector. I used rubbing alcohol first to clean the glass and chip area.

Not a perfect solution, but better than $700+ for a display.

When you cutting the edge you can also put some books under the display part to keep it level and easy to go around as you cut. If you cut the bottom all the way with the razor, you will have a clean cut and you can pull it towards you while the unit is as described in the guide steps 18-22. I do not like the idea of standing up the unit as there is more pressure on the bottom edge of the glass from the displaly

I have now ordered my second LCD screen from vendors on Amazon and both of these have arrived with the wrong connectors. My iMac is a (late 2013) model A1419 and even though the LCD replacements I ordered earlier claim they were for an A1419, the internal plug-ins are different sizes than my iMac requires. My iMac requires a 6 wire connection on the right hand side flat cable connector, NOT the 12 wire connector that came on the LCD replacement screen and the cable connector in the middle of my iMac screen is about 1/4" shorter than the connector on LCD replacement screen I just received. Can this be so hard??? Can anyone tell me how to make sure I order a replacement LCD screen with the right connectors for my iMac (late 2013) model with the right internal cable connections? Thank you, Dave J.

Hi everyone

I have a tip for everyone who removed the screen on your iMac. If you don't need to replace the screen, I try to avoid removing the lower section of the sticker/glue on the screen. If you are just replacing hard drive or anything minor. Why? Factory glue is better and it is still perfectly line up. When trying to place the screen, there is always a risk of sticking offset by few mm and those dam stickers won't let you move or redo it.

Also i like to keep sticker/glue free on the side and top part of the screen. I just have the lower section and use few inches or black electrical on top corners to hold the screen in place. Why? For future repair or cleaning. If I want to change or upgrade hard drive. I just remove the tape and have access into the iMac without the hassle of cutting the glue again. If you just have the stickers/glue on the bottom, you can just move the screen like engine hood of your car - up and down. Of course just be careful if need to move the iMac around.

Dave - my advice on ordering parts, remove the old screen first, check the part number and contact your supplier. Don't order by the iMac model number. The screen will have a sticker and you will know for sure which part to order. Also I always remove the screen first before I order. In case you screw up, you need to order other parts, or worst. Machine is dead, no point to order a $400-600 screen.
