Introducción

La eliminación de la pantalla en el iMac de finales de 2012 requiere cortar el adhesivo con una herramienta de apertura iMac especializada. Una vez que haya completado su reparación, deberá seguir nuestra [guía | 15624 | Guía de cinta adhesiva] para raspar el adhesivo viejo y reemplazarlo con nuevas tiras adhesivas de doble adhesivo.

Partes

No se requieren partes.

  1. Comenzando a la izquierda de la pantalla, cerca del botón de encendido, inserte la herramienta de apertura iMac en el espacio entre el panel de vidrio y la carcasa trasera.
    • Comenzando a la izquierda de la pantalla, cerca del botón de encendido, inserte la herramienta de apertura iMac en el espacio entre el panel de vidrio y la carcasa trasera.

    • El centro de la herramienta de apertura iMac evitará que empuje demasiado la rueda. Si utiliza una herramienta diferente, inserte no más de 3/8 pulg. En la pantalla. Se corre el riesgo de cortar los cables de la antena y causar daños graves.

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

    Clark Green - Contestar

    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.

    Dan -

    Removing the original adhesive is easier than removing newly applied adhesive (e.g., if you have to reopen iMac).  If you should happen to need to reopen the iMac, please use extreme caution and highly consider my suggestions below.

    When using the pizza cutter tool, do the first few steps in reverse starting with step 8.  Starting on the left side is better since this is where the adhesive is narrowest.  The right side has two antennas and the top right has one, see the pictures for step 18-21, they are the brass colored metal rectangles near the edges.  The adhesive on these pieces are wider and therefore have more holding power.  The thickness of the pizza cutter tool is enough to crack the glass.

    Walter Hayden - Contestar

    Continuing from my previous comment.  To remove the adhesive on the right side you’ll need to create a very slight gap to give the pizza cutter some more room.  Do this by cutting the adhesive on the left side up and around to the camera.  Before attempting to cut the right side. Carefully slide the plastic cards (I purchased two sets) to ensure the adhesive on the left top and side is completely free.  Now slowly move towards the right side.  After every inch or two of removing new adhesive, slide the card over to create this slight gap.  Be careful to not move the card too close to where the adhesive has not been cut.  You want to create a very slight gap without creating too much pressure.  Use extra caution with approaching the areas where the antenna are since the adhesive is stronger here and will need some additional cutting.  Follow this approach all the way around the right side.  Be careful to not create too much pressure at any one time.  Good Luck!.

    I would highly, highly, highly recommend AGAINST doing this at home. I followed these instructions to a T, and still somehow managed to have the screen not be able to turn on after the hard drive replacement. Then, once you’ve opened your Mac yourself, Apple will refuse to fix anything on the computer, and even other third party, Apple-authorized repair facility will refuse to repair it for you, and you will have to locate a non-authorized Apple repair facility. There, I am having to pay ~$600 to fix things that got screwed up, even though I followed the instructions here to a T, step by step, and did everything slowly and methodically.

    Beware, if you’ve never done this before, that be locked out of ever being able to use an Apple repair facility, or Apple-authorized repair facility, if you mess things up here now.

    Luke Gibson - Contestar

    I performed this on a Late 2015 iMac and there weren’t any significant differences to these steps, but I did find the repair to be nerve-wracking. My model cost nearly $3,000 and about 10 steps into this guide (which I did fully read ahead of time) I was thinking, “what have I got myself into?” But I didn’t rush and happily I’m typing this on my repaired iMac! I found a video from OWC that was more useful than the photos in this guide for certain steps: https://vimeo.com/139364064

  2. Use la herramienta como un cortador de pizza: gírelo a lo largo del espacio y cortará el adhesivo de espuma a través del centro.
    • Use la herramienta como un cortador de pizza: gírelo a lo largo del espacio y cortará el adhesivo de espuma a través del centro.

    • Asegúrese de empujar siempre con la manija detrás de la rueda de corte. Si tira, la rueda podría salirse del mango.

    • Ejecute la herramienta hacia arriba a lo largo del lado izquierdo de la pantalla.

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

    Gerry - Contestar

    • Continúe girando la herramienta hacia arriba en la esquina superior izquierda.

    Agregar Comentario

    • Corte el adhesivo a lo largo de la esquina superior izquierda de la pantalla.

    The pizza cutter will sink in all the way to the tool handle when the adhesive is full cut, but don’t feel you have to do this in one motion. Some parts cut easier and some require a lot (like 20x) of gentle back and forth.

    Anthony Zimmerman - Contestar

    • Continúa por la parte superior de la pantalla.

    • Es posible que desee ejecutar la herramienta hacia adelante y hacia atrás a través de lo que ya ha cortado un par de veces, para asegurarse de obtener la mayor cantidad de adhesivo separado como sea posible.

    Agregar Comentario

    • Empuje la herramienta alrededor de la esquina superior derecha de la pantalla.

    Agregar Comentario

    • Mueva la herramienta hacia abajo a lo largo del lado derecho de la pantalla.

    Agregar Comentario

    • Finalice empujando la herramienta de apertura hacia la parte inferior del lado derecho de la pantalla.

    • En este punto, querrá volver a ejecutar la herramienta en toda la pantalla para asegurarse de cortar la mayor cantidad de adhesivo posible.

    • Si bien la herramienta de apertura hizo la mayor parte del trabajo, la pantalla aún se adherirá ligeramente a la carcasa. Se necesitará una tarjeta de plástico para liberar el último adhesivo.

    • Coloque el iMac boca arriba en una mesa.

    • Comenzando desde la esquina superior derecha del iMac, inserte una tarjeta de plástico entre la pantalla y el marco.

      • Tenga cuidado de no insertarlo más de 3/8 ", o puede dañar los componentes internos.

    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!

    Peter Fischer - Contestar

    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

    Edgar Broekema - Contestar

    i successfully upgraded two imacs. one opened with ifixit pizza knife and another with a regular paper knife. however, when i had to open the first one once again i broke its screen glass. it seems ifixit adhesive strips are too strong. next time i’ll try to use heater to weaken glue tension.

    Eugene Kharkov - Contestar

    • Gire suavemente la tarjeta de plástico para abrir el espacio entre la pantalla y el marco.

    • Muévase despacio y tenga cuidado de no estresar demasiado el cristal de la pantalla; solo necesita hacer un espacio de aproximadamente 1/4 ".

    My children tend to collect cards like this from hotels, Disneyland, old IDs, iTunes cards, gift cards etc. They came in handy for this step. After wedging in the first card into the left corner, I wedged the left corner, then added cards along the bottom edge. Finally I continued to push in additional cards to existing cards and found that this created a smooth even pressure along the display top. At 2-3 card-thickness the last of the adhesive let go, gentle as a baby.

    Anthony Zimmerman - Contestar

    • Asegúrese de detener el corte antes de la cámara iSight en este paso, o puede dañarlo.

    • Deslice la tarjeta hacia el centro de la pantalla para cortar el adhesivo restante.

    was denn jetzt? Vor der Kamera aufhören, oder in Richtung Bildschirmmitte schieben, um DEN REST zu entfernen? Wenn ich vor der Kamera aufhöre, kann ich nicht alles an Kleber entfernen.

    Julia S. - Contestar

    • Vuelva a colocar la tarjeta en la esquina y déjela allí para evitar que se reubique el adhesivo.

    Agregar Comentario

    • inserte una segunda tarjeta en el espacio entre la pantalla y el marco en la esquina superior izquierda.

    Agregar Comentario

    • Gire suavemente la tarjeta, aumentando ligeramente el espacio entre la pantalla y el marco.

    • Al igual que con el otro lado, muévase lentamente para permitir que se rompa el adhesivo, y tenga cuidado de no sobre tensar el cristal de la pantalla.

    Agregar Comentario

    • Deslice la tarjeta de plástico hacia el centro, deteniéndose de nuevo justo antes de la cámara iSight.

    Agregar Comentario

    • Inserta la tarjeta nuevamente en la esquina superior izquierda.

    Agregar Comentario

    • Solo levante la pantalla unas pulgadas; todavía está conectada al iMac mediante cables de datos y alimentación.

    • Con las tarjetas insertadas como se muestra cerca de las esquinas, gire suavemente las tarjetas para aumentar el espacio entre la pantalla y la carcasa.

    • Si hay secciones que parecen pegarse y no se separan, deje de girar y use una de las tarjetas para cortar el adhesivo en el área problemática.

    • Comience a levantar la parte superior de la pantalla desde el marco.

    I would recommend using suction cups at this stage to lift the display.

    Marco De Palma - Contestar

    • Mientras sostiene la pantalla con una mano, use la otra para desconectar el cable de alimentación de la pantalla.

      • Levante la pantalla lo suficiente para tener un acceso fácil a las conexiones, pero no tanto que estire los cables y acentúe sus conexiones (aproximadamente 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!

    Alastair Lack - Contestar

    At this step, if you mess up anything with these 2 cables, especially when plugging them back in, even if you think you’re following the instructions here to a T, then you’re screwed.

    I would highly, highly, highly recommend AGAINST doing this at home. I followed these instructions to a T, and still somehow managed to have the screen not be able to turn on after the hard drive replacement.

    The display cable, the wider one, has a lock on it , usually a plastic tape lift tab to release it, once thats flipped it should come out fairly easily, if your experiencing resistance and the cable isn’t coming out then check for this lock/latch, the power cable just pulls out, just don’t rush it everything should go fine, fairly easy to do with the end result a working iMac

    Ed tabickman - Contestar

    • Levante el soporte de retención de metal en el cable de datos de la pantalla.

    • Desconecte el cable de datos de la pantalla.

      • Esta es una conexión delicada que se puede romper fácilmente. Asegúrese de sacar el conector del cable de datos de la pantalla directamente de su zócalo, hacia la parte superior del 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..

    chansung park - Contestar

    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.

    Dan -

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

    redfoxydarrest - Contestar

    Sorry damaged display

    Dan -

    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.

    john - Contestar

    I agree! +1

    Jim Reitz -

    [|There are 2 cables to disconnect on my Mac (?). Also, I don’t see a metal retaining bracket. I can take a picture, but cannot attach. I got the glass loose with no problem, but am worried about damaging the cables]

    Can anybody upload an image of how the display can get damaged from removing it? I find it hard to believe (though I’m reading the horror stories here) that a whole display can get damaged. Especially when many of us were following to a T and being VERY CAREFUL.

    Thanks.

    Bryan - Contestar

    • Levante la pantalla hasta una posición casi vertical.

    • En este punto, todavía hay una tira de adhesivo en la parte inferior de la pantalla, que mantendrá la pantalla en el marco como una bisagra. Puede aflojar este adhesivo al subir y bajar la pantalla varias veces.

    • Retire la mayor cantidad de adhesivo posible agarrándolo por los bordes exteriores, y luego tirando o rodando hacia el centro.

    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 !!

    dforgues - Contestar

    Thanks Stef, this has saved me! Simple yet very effective.

    David Zemsky - Contestar

    Yep, I cracked the lower corner of the display as well. I failed to work the adhesive enough to loosen it sufficiently. Be careful, I just had to buy my customer another screen!

    Peter Haigh - Contestar

    There seems to be missing a step or two. As I was removing the old display, there are two wires that need to get transferred to the new replacement display. There is not note about these two wires located at the top of the display. The 1.128-inch ribbon cable and then this other 4-inch long, two-wire cable that goes to a very small circuit board that is 1/4 by 3/8 of an inch and seems to be adhered to the panel.I have not been able to get this cable off the old display. There is a port for it on the replacement display.

    Note: When ordering this screen, and plastic cards as noted tools, ifixit.com did not list the pizza cutter or the new replacement adhesive strips. So now I’m not sure how to get the new one on and secure.

    Todd Derek - Contestar

    The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

    Andrew Stephens - Contestar

    • Si es necesario, se puede usar una tarjeta de plástico para cortar las secciones restantes de la tira adhesiva inferior.

    • Tenga mucho cuidado de no tocar los cables del condensador ni las juntas de soldadura expuestas en la parte posterior de la fuente de alimentación (enmarcadas en rojo).

    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..

    Wizbang FL - Contestar

    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 - Contestar

    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.

    Eric - Contestar

    [|I opened up my iMac and there’s no HDD or SSD in that spot. its just empty.]

    John Warmann - Contestar

    Please update the picture to include the RED BOXED IN AREA that you refer to on all three pictures in this step. I have had a few zaps from these supplies and it is not pleasant.

    Charlie Nancarrow - Contestar

    • Tenga mucho cuidado al manipular la pantalla: es grande, pesada y está hecha de vidrio.

    • Levanta la pantalla del marco y retírala del iMac.

    • Puede ser necesario levantar lentamente de un lado, para pelar contra el adhesivo restante.

    Agregar Comentario

    • Con la bisagra libre para moverse, el iMac estará desequilibrado y difícil de trabajar. Las reparaciones se pueden completar con el iMac, pero son más rápidas y fáciles con una cuña de servicio iMac.

…thanks, but i have a crack on the screen as i was lifting it up. after reconnecting, there where lines on the display. what should i do.?

zeerowbadman - Contestar

Something you may want to include for anyone replacing their damaged screen with a new one:

The replacement screens from LG more often DO NOT come with the thermal sensor attached, which means if you replace the screen without transferring the thermal sensor from the old LCD module, the computer will go absolutely insane, rendering it unusable.

This means re-opening the iMac and destroying the brand new adhesive strips. Because I had no idea this sensor existed, much panic ensued before I was forced to rip everything apart again and ultimately securing it closed with packing tape while I waited for the new adhesive strips to arrive in the mail....Not to mention the computer belongs to a client who lives 3 hours outside of the city.

placebomessiah - Contestar

Sorry, could you help me? What thermal sensor?! Could you explain?

cristiano -

See the thin twisted black wire on the back of the display in this photo? The one that ends in a small piece of black tape:

https://d3nevzfk7ii3be.cloudfront.net/ig...

that piece of tape covers the tiny thermal sensor at the end of that wire. It is not included as part of the new display, and must be transferred from the old display or your computer will turn into a nightmare.

placebomessiah - Contestar

But this is for model emc2546 too? And how you can transfer thermal sensor? Thank You!!!!

cristiano -

Where can I order the screen? There's a local shop nearby that offer to do the repairs for 550€ (!) and they claim it's because it's not just the glass but also the LCD that needs to be replaced. Is this true?

Robin Groenevelt - Contestar

I got mine from a distributer in china

it's actually an LG screen. it's tricky to do business with them, because their english is very limited, but with patience, everything works out

placebomessiah - Contestar

Hey placebomessiah, could you let me know where you bought it. I am in the same position and need the front display cause I cracked it while trying to open it to replace my hard drive .

Riki -

can you tell me where you bought it or how it is called?

Marc Klingelfuss -

Based on the pictures for the Late 2012 27" and Late 2014" 27" Retina screen replacements, the screens and connectors look identical. Has anyone tried to install a 5K Retina Display on a Late 2012 or Late 2013 27" iMac?

spencer - Contestar

Seems like no one has tried it before but I am very curious to know as well. Since my Applecare has lapsed, I am considering getting my Late 2012 27" imac's screen to 5K Retina display too.

potzkie15 -

not possible. apple parts are proprietary. Just like you cant put a iPhone 6s screen on an iPhone 6, you can’t put a 5k screen on a 2012 non 5k model.

Hunter Berry -

Hi there, do you know where I can buy the Retina display 5K at reasonable price? The Apple asked me 900 euro to repair it!!

Dee - Contestar

Hi, where can I buy the display?

yoisel1979 - Contestar

be very careful when you cut the tape. I really advise you to buy the pizza cutter-style tool. With the plastic card I broke my screen :(

alex - Contestar

Looks like I accidentally went too far in and have damaged the LCD, put it all back together and have lines.

** wish I had that mini pizza cutter **

Otherwise advice perfect!

Jon Regler - Contestar

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 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 my LCD replacement screen and the connector in the middle of the screen is about 1/4" shorter than the connector on the LCD replacement screen. 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. Thank you, Dave J.

Dave Jensen - Contestar

I'm looking to add an SSD in my 27" iMac (Late 2012), but I have a problem. I bought this very cheaply secondhand as it has a small chip and crack in the glass on the top left corner. It doesn't affect the display whatsoever, so has never bothered me. However, I'm really worried what might happen if I have to remove it to put in the SSD. I can't work out from the pictures the depth of the glass that is attached to the screen. Am I going to cause terrible damage by going ahead with this? Here's a picture of the crack.

Unfortunately, I had to reopen my iMac because of my stupid perfectionism! I had clued it not perfectly. So I had to cut the new tapes, what was more difficult than the original ones. After I had replaced the tapes I assembled everything back together and there it was, a very thin yellow line. I could have cried!

Now I’m wondering if there is a solution to repair it instead of replacing it.

Appreciate every hint. Thank you!

Marc Klingelfuss - Contestar

Because the new tapes were much stronger than the original ones, I broke the opening tool. I continued with the cards and probably broke the screen because of that.

So don’t use the cards to open your screen!
