  • Diese Schraube lässt sich nicht komplett vom Blech entfernen.

  • Entferne das Schutzblech vom iMac.

isn't it actually pc2-5300s ?

grze - Antwort

  • Die Glasscheibe ist auf der Frontblende mit insgesamt 14 Magneten befestigt.

  • Setze zwei Saugheber auf gegenüberliegende Ecken der Glasscheibe.

  • Zum Anbringen der von uns verkauften Saugheber positioniere zunächst den beweglichen Teil des Griffs parallel zur Glasfläche. Drücke den Griff dann leicht gegen das Glas und hebe den beweglichen Teil des Saughebers, bis er parallel zu dem anderen Griffteil ist.

  • Wenn die Saugheber nicht haften, reinige sowohl die Glasscheibe als auch die Heber mit einer milden Seifenlauge.

At this stage and later handling the LCD I found thin cotton gloves helped to reduce smudges

john31 - Antwort

My GPS unit's car mount suction cup worked nicely here - couldn't find any at the store and didn't want to wait for mail order!

Two cups would make it easier but one is fine if you place it in the center and are careful to pull the panel straight out.

Mathew Hendry - Antwort

Why use suction cups when some finger nails will do the job nicely, though a plastic spudger might work too. Start at a top corner. Prize the glass away from the case and leave finger nails in. Move the other hand along the top edge and then with finger spread peel the screen cover away. Be careful not to twist plastic I suppose, but I've had no difficulties.

damianwise - Antwort

3M Command Strip hooks in opposite corners is another fabulous option when suction cups are not available!

Adam McCombs - Antwort

Tape works fine, here. Search for a YouTube video for a simple look-see.

Richard - Antwort

I didn't have any suction cups, but my pencil sharpener (the kind that suctions to the table) worked great. I put it on the middle and lifted straight up.

Lisa Mac - Antwort

For a quick 'n' dirty alternative "tool" for this step, take a look at IKEA's Stugvik suction hooks: they provide an excellent adjustable grip. Just used it to take apart an EMC2133. Cheers!

hadderakk - Antwort

Suction cups usually available at Home Depot or Lowes, in the flooring section. (They're used to handle large ceramic & stone floor tiles.)

Griff in Fairbanks - Antwort

  • Ziehe die Glasscheibe gerade nach oben vom iMac ab.

  • Die Glasscheibe verfügt auf ihrem Umfang über mehrere Positionierstifte. Um ein Abbrechen der Stifte zu vermeiden achte bei der Demontage darauf, die Glasscheibe wirklich senkrecht nach oben zu ziehen.

  • Reinige beim Wiedereinbau das LCD und die Innenseite der Glasscheibe sehr sorgfältig, da sonst ggf. Staub und Fingerabdrücke verbleiben, die störend sichtbar werden, wenn das LCD eingeschaltet wird. Es empfiehlt sich, die Glasscheibe beim Ausbau mit der Innenseite auf einer frischen Aluminiumfolie zu platzieren, um Verschmutzungen zu vermeiden.

In order to avoid unnecessary smudges and what not I covered the LCD itself with some plastic wrap while doing the hard drive upgrade. When I reinstalled it all I needed to do was blow off a few dust particles.

robgendreau - Antwort

While you are at it, it is worth cleaning out dust within the case to help with cooling - particularly around the fans and vents.

For the screen I used a lens cleaner from my camera bag. These have very fine fibers and won't leave detritus.

Mathew Hendry - Antwort

Note that the front glass panel is quite light. When reassembling I found it impossible to get the LCD free of dust with the computer lying on its back. I had success with standing the computer up, tilting the LCD down as far as it goes, holding the glass panel upright in front of the computer (about 1 foot away), lightly spraying both the LCD and the back side of the glass panel with compressed air, and then attaching the glass panel (with the computer upright). It took me 5 tries before it was completely clean of dust once the front glass was on.

axel - Antwort

Although I do not advise it, you can substitute the suction cups with two strips of duct tape along the sides of the glass, with the tape attached to it's self in the middle of the strip

Mike Hostetler - Antwort

  • Entferne die folgenden 12 Schrauben, welche die Frontblende am dahinter liegenden Gehäuse befestigen:

    • Acht 13 mm T8 Torx.

    • Vier 25 mm T8 Torx.

On the 24" EMC2134 there are 3 screw sizes: 6x13, 4x20 & 2x30mm, particular note should be made of their location.

john31 - Antwort

Note for the less experienced.. the case is plastic and the metal coarse thread screws will easily cut a new thread in the hole if you don't line up the screw in the original thread. Do this a few times and the hole will be stripped and the screw no longer tightens.

TIP:- place the screw in the hole and rotate BACKWARDS/counter clockwise (for RH threads) until you hear/feel it click/drop into the original thread then tighten the screw down. rotate it a couple times to get the feel of things. If there is any significant resistance you probably don't have the original thread.

This trick also works on the fine metal thread screws and can help avoid cross threading them.

HIH

Richdave - Antwort

On the 24 inch iMac Model A1225 EMC #2134, the two T8 Torx screws in the middle are the longer of the four total bottom 25 mm screws. Just a note for reassembly.

bhoffs - Antwort

This step is not really explained here with pictures. But you can check this same step in another guide to help you : iMac Intel 20" EMC 2266 Front Bezel Replacement

thibault - Antwort

I'll echo Thibault's comment. This guide does not actually tell you when and/or how to remove the bezel! Click on the other guide he linked to see the photo and instructions.

steven - Antwort

Make sure you're ram slot at the bottom is open to remove front frame bezel

edgain99 - Antwort

I think you're missing this step: With the iMac lying on its back screen facing up, grasp the aluminum sides of the bezel and carefully pull it straight up. Then disconnect the microphone cable. Took me a while to figure it out.

Richard Cacciato - Antwort

I found it helpful to use a few lids from spaghetti sauce jars to hold the different screws. I used a sharpie to mark the inside of the lid w/ location taken from or the step number from directions. Then I placed a small magnet under the lid to hold the screws inside the lid in case I accidentally jostle something on the table. Worked great! You can also use a magnetic knife bar to line up the lids in sequential for the project.

tom - Antwort

I cut a hardwood block and drew the outline of the the iMac shape with the base as key. I then drew another two lines at 1/2” and 1” all around from the outline. This done I drilled holes for each screw (12 Outer securing the front bezel to the rear case , and 8 Inner screws securing the display panel to the rear case ). That way I don’t lose any or get them mixed up.

jmadams - Antwort

  • Löse den Stecker des Mikrofonkabels. Entferne dabei das Band wenn nötig.

  • Damit die Frontblende richtig sitzt sollten Mikrofonkabel und Stecker im Freiraum neben der Kamera platziert werden.

I avoided this step by just flipping the housing over and having it lay flat on the table. The tape on mine was on really tight, and I risking ripping the wires out of the connector if I messed with it (I didn't have some really small scissors which might have helped removing it). I would suggest either securing the body of the iMac and the housing to the table you're working on, or somehow securing the housing to the body, so that it doesn't move around accidentally, since it's only hanging on by a very thin wire at that point.

robgendreau - Antwort

^^^ This! This tutorial should be amended for this step. Much, much easier and less damage-prone.

(There really oughta be a step addressing the removal of the bezel as well.)

cklarson -

Make sure you do not pull this apart by the wires. Have a firm grasp on the plastic parts. Do not force back together. It only goes back together one way. Also, it is crucial when placing the aluminum bezel back in place that this wire is out of the way. It often gets in the way and is easily damaged.

Kyle Freeman - Antwort

CAUTION - To disconnect the cable, you'll need to support the bezel while you carefully extract slack microphone cable which is tightly tucked within the iMac. (I didn't have this guide's 'notes on' and missed robgendreau's warning - then inadvertently shifted the bezel and busted my microphone cable in this step.)

dagnew - Antwort

Don't forget to pull the microphone cord out before you put the panel back on. Otherwise you will have to go back and remove screws to find that microphone cord

Melvin Hines - Antwort

As robgendreau says, avoid this whole step by opening the bezel and laying it upside down above the iMac, still connected by the mic cord, just carefully. Then replace the battery, suck/blow out your dust, and carefully rotate the front bezel back over the iMac from where you removed it. No cord manipulation or damage at all!

recmsoj - Antwort

  • Ziehen Sie den Stecker des LCD-Temperatursensors gerade nach oben aus dem Sockel auf der Hauptplatine.

  • Ziehe dabei falls erforderlich das Kabel des Sensors hinter der Hauptplatine hervor.

  • Überprüfe beim Ausbau des LCD die Kabelführung des Sensors. Achte darauf, dass das Kabel beim Wiedereinbau des Bildschirms nicht eine der Schrauben für die Frontblende blockiert.

This was the most confusing step, because the video shows MJ just tilting the monitor open, and I had a ribbon cable hooked up to it. Finally figured out that the ribbon cable was connected to the LCD temp sensor cable, and it was neatly tucked under the adjacent fan. Had to pull it pretty hard to get it out from under the fan, and then could tilt the LCD. Instructions are not completely clear about this, only that you may have to reroute the cable around the motherboard.

d3nn151950 - Antwort

I agree, there is no sign of how to remove the bezel (it took me several minutes to understand it was even the bezel that came off here) in these steps (in all the guides for this model, in fact). On step 4 says remove the LCD screws, and suddenly step 6 shows innards and fans etc - !! - What about showing the bezel being removed here - super confusing and not up to usual ifixit high standards.

hutchwilco - Antwort

If you rush through the reassembly, it's very easy to miss reconnecting the LCD Temp Display cable. I just did it and one of the fans came on full-speed and stayed there through a new macOS install. Did a Google search and found mention of this symptom. At first I was thinking I switched one or more of the inverter cables but this guide shows that this is not a problem. Once I reviewed this step, the problem was obvious as was the solution. Thanks again, iFixit, for saving my nappy behind.

barryjaylevine - Antwort

  • Entferne die zwei 5,3 mm Torx T6 Schrauben, welche das Bildschirmkabel an der Hauptplatine befestigen.

My Torx 6 driver purchased from ifixit didn't fit the screws well and potentially would strip them. Had to purchase a better driver to fit better in order to loosen these screws.

kakisback - Antwort

reinstalling these screws requires extra care to be sure you don't drop it and loose it under any of the other components.

kakisback - Antwort

Make sure not to drop the screws.

ulan - Antwort

Removing these screws was the most difficult part of the whole job. They were tight and felt as if the heads were about to chew up. I had to press really hard and jerk the screwdriver counter clockwise to loosen them. Despite others' warnings, I managed to drop a screw when reinserting.

kevinp - Antwort

The only tool I needed to buy was the T6 Star Bit - the first auto store I went to had it. These screws are tiny so you have to be careful not to drop them!

James Miles - Antwort

When reinstalling these tiny screws, consider placing the iMac upright. That way when you (inevitably) drop these tiny screws, you don't lose them in the guts of the computer where they are likely to fall into a fan.

stown1211 - Antwort

Yes, this step is very difficult. I finally used a magnet to magnetize the torx driver, and that helped immensely...however, that was AFTER I lost the right one inside the computer. You really only need one screw to reattach the monitor connector, however.

d3nn151950 - Antwort

Argh! I dropped my right screw into the bowels of the iMac. I can't find it anywhere and am loath to leave it rattling around as well as to tear down the machine any further.

steven macfarlane - Antwort

Well, I followed the instructions for right-speaker removal and optical drive fan removal and still couldn't find the right screw. I couldn't hear it rattle either so figured it was wedged somewhere. Using an inspection mirror and flashlight, I finally found it. It had fallen down and wedged between the PCB and the plastic housing (below the ports). I was able to slide it toward the right until it came to the void left by the right speaker where it fell out into my hand.

steven macfarlane -

It's true, these were super tight. I only had a T5 which worked on the first screw, but the second wouldn't budge. Ended up filing the tip off the T5 bit - presto! - instant T6.

marcintosh - Antwort

I Think the real screw size is 3.5 mm T6 Torx, not 5.3 mm

raul - Antwort

Dropped those little bastards like 2-3 times into the deeps of my iMac. The right one is really tricky. If you drop it: better get yourself very thin tweezers and gently shake your mac. :(

Popelnase - Antwort

Note that just below where you are working is the PRAM battery. If you have never replaced this, now is a good time so you won't have to open the machine up again in the near future. The battery is a CR2032.

mattgauntt - Antwort

Taking all the warnings into account about losing these tiny screws, during removal and replacement I held onto the screws tightly with a very fine needle nose tweezer. Fortunately I managed not to lose them either out or in. I highly recommend using a small gripper during this step.

recmsoj - Antwort

This step together with step 8 can be avoided. Leave this cable alone. You will have plenty of space to lift the LCD and rest it against a wall or any other object. Again...

1) don't waste your time if you know what you are doing

2) don't complicate things and remove unecessary cables.

Scorps - Antwort

This is true. There's plenty of space to work without taking the whole LCD out, either by resting it on your head, having someone hold it, or propping it on something. This makes steps 7, 8, and 10 unnecessary.

hillman -

While you have the case open this would be a good time to replace the PRAM battery and carefully clean the fan and interior of the case with Q-tips / compressed air.

John Fisk - Antwort

These screws are Torx 7 - at least that was what

I used on them and got a prefect tight fit ... .

I was able to disconnect the two connectors to the front easily. With those off, I just rotated the LCD out of the way to expose the hard drive. Again, make sure it's stabilized if you do this so that when you yank on something else you don't send it flying.

robgendreau - Antwort

I did a HD replacement on my 24 inch iMac. It's basically the same, but it does not have disconnectable invertercables. Instead, there's just one cable that's can't be disconnected. It sits too tight to rotate the display to the degree that you can lean it against something, so the only way to get the job done was to call in an extra set of hands to hold the display while I took out the hard drive.

Marijn - Antwort

On the 2134 model, I found that the LCD must be lifted from the RIGHT (not the left as per the 2133 guide) - the connector wires are covered in nylon housing and it's way easier just having someone hold the LCD vertical whilst you replace the HDD, unless you have small fingers and feel like disconnecting completely ...

simon - Antwort

During reassembly, make sure that the data and temperature cables will reach their sockets before inserting the eight screws.

kevinp - Antwort

  • Entferne bei angehobenem Bildschirm die vier Stromkabel.

  • Lege beim Zusammenbau die vier Stromkabelanschlüsse in Hohlräume zwischen den Komponenten an der Rückseite, so dass der Bildschirm bündig aufliegt.

  • Beim Zusammenbau ist die Reihenfolge der Stromkabel innerhalb eines Anschlusses austauschbar.

  • Sollte beim Austausch der Festplatte eine weitere Person helfen, so ist es (nach Lösung des Temperatursensors und des Bildschirmkabels im vorherigen Schritt) möglich, den Austausch bei angehobenem Display vorzunehmen.

Make sure to not squeeze the inverter-cables between the superdrive and the display when putting the display back on !

epzzky - Antwort

This was the only step different for my 2134 - it is just one cable that connects to the monitor - disconnect the monitor end rather than the motherboard side.

Jim Laredo - Antwort

There is no need to discnnect the inverter cables if display is positioned against a wall or something of the sort. Make sure it doesn't tumble over !!!

info5825 - Antwort

For 24" iMacs, a single power cable is attached on the left side of the screen. To remove the cable, lift the screen from the right side and rotate it to the left. Remove the black plastic protector on the back of the screen and disconnect the cable.

Matt Stichnoth - Antwort

Make sure you squeeze the two ends of the inverter cable together firmly - if not you will get yellow areas on your screen. One of my cables had not quite been clicked together, and I had to unscrew everything all over again.

Philip - Antwort

So does it matter which ones are connected to which?

That is, at each end there are two connectors (one pink/black the other light blue/dark blue on the "male" side). The "female side appear identical. Does it matter if the pink/black "male" one is connected to the wrong "female" one?

Mark Gibson - Antwort

Mark, did you ever get an answer about the connectors?

Mike -

Agreed this is an unspecified issue and i'm surprised it's not covered? Did everyone else just guess?

kainatticus -

Managed to avoid this step just lifting the lcd panel and holding it with my... head ;)

Antonio Bernardini - Antwort

I'm trying to find some information on replacing the power supply temperature sensor cable. Mine broke during removal of a bad power supply.

Mike Overholt - Antwort

found out that taking the 2 inverter cables (top right corner underneath LCD) and mixing them will not work. I got beeping sound. So...you really need to mark the 2 white sockets with P (pink) and B (for light blue-gray color). Then everything will come out smoothly. Again... inserting the 2 inverter cable sets into the right socket DOES MATTER.

Scorps - Antwort

Re: Scorps comment above - I got the “beeping” too. Does anyone know how to resolve it, i.e. identify which goes with which? Other than trying every combination?

mchlgrblsk - Antwort

My screen is just Grey? anyone else have this happen?
