Introduzione

Rimozione della mascherina anteriore per accedere ai componenti interni dell'iMac.

    • Poggiare l'iMac sul lato anteriore su un tavolo, con il bordo inferiore rivolto verso l'utente.

    • Allentare la vite con testa a croce al centro dello sportello di accesso.

    • La vite resta all'interno dello sportello di accesso.

    • Rimuovere lo sportello di accesso dall'iMac.

    The grid won't fall off by itself. You'll have to help it. Use the smallest screwdriver you have; the Torx 6 worked fine for me. It should enter in one of the many holes composing the grid. Use it as a lever to ploy the grid a little bit. You may catch it with your fingers and that's it.

    Be carefull not to damage the hole by a too strong leverage.

    much more safer to use duct tape, instead of torx 6. (glue it along the length of the grid and pull). it will loose instantly and smooth;)

    Anyone know a guide to replace the plastic piece this screw connects to? I accidentally forgot this step - went to remove the front bezel and bent the plastic piece the access door connects to.

    • Il pannello di vetro è fissato nella mascherina anteriore con quattordici magneti posizionati lungo il perimetro.

    • Far aderire due ventose agli angoli opposti del pannello di vetro.

    • Per far aderire le nostre ventose, per prima cosa posizionarle con la maniglia semovente parallela alla superficie del pannello di vetro. Tenendo delicatamente la ventosa contro il vetro, sollevare la maniglia semovente finché non è parallela all'altra maniglia.

    • Se la ventosa non aderisce, provare a ripulire il pannello di vetro e la ventosa con un solvente delicato.

    A good alternative to the two heavy duty suction cups is a regular household plunger.

    Also, 2" wide packing tape. Maybe a 6 or 8" piece, folded in the middle to give you say, a 1-2" "handle". Make a pair of these. They look like a capital T but with a short vertical part (the handle), and a wide top I the sticky wings). Get the good 3M tape, it's strong, and it peels off clean without leaving any glue from the screen.

    Barry Coyle -

    for me one household plunger did the trick!

    • Estrai delicatamente il pannello di vetro dall'iMac.

    • Il pannello di vetro presenta diversi piedini di posizionamento lungo il perimetro. Per evitare di staccare i piedini dal pannello di vetro, fare attenzione a rimuoverlo solo tirando verso l'alto.

    • Pulire con attenzione la parte interna del pannello di vetro e l'LCD, poiché la polvere e le impronte digitali saranno sgradevolmente visibili durante l'accensione del display.

    • Quando sostituisci il vetro, assicurati che non ci sia nulla tra il vetro stesso e il suo supporto. Eventuali cavi volanti potrebbero danneggiarsi o rompere il pannello.

    Another approach that worked for us was to get 4 small plastic wedges (the kind used in iphone screen replacements). Working one corner at a time you can use a cheap suction cup to pry just that corner up enough to slide the wedge in. Then proceed to the next then next, etc. Once all 4 have the wedges under them the glass should be away from the body all the way around, then just carefully lift it the rest of the way up.

    • Rimuovere le 12 viti seguenti, che fissano la mascherina anteriore al case posteriore:

    • Otto viti Torx T8 da 13 mm.

    • Quattro viti Torx T8 da 25 mm.

    • Nell'iMac Intel modello A1225 da 24", le due viti nella parte inferiore centrale sono lunghe (26 mm), le quattro ai lati (due a sinistra, due a destra) sono medie (18 mm) e le restanti 6 (quattro nella parte superiore e due negli angoli inferiori) sono corte (14 mm).

    I would strongly suggest taping the screws down on a piece of paper towel or cloth in the same order you take them out, as there are different lengths in no particular order and they don't all fit into just any hole. Unless you keep track of which hole each screw belongs, there is no other way of knowing. I stress taping because I didn't tape mine down and after bumping the table I was working on they scattered, leaving me to guess.

    Even better, use an ice cube tray to keep the screws from each step together.

    maccentric -

    how about using the magnets near the screws to keep their positions?

    Andy -

    I use an 18 count egg carton (or two) and label each egg slot with a Sharpie. Works great.

    As a rule with iFixit repairs, for years I've been printing the guides, applying scotch magic tape near each picture (which allows me to reutilise the paper prints in the future), neatly putting the appropriate screw next to their picture and taping them down with scotch magic tape.

    Even if I have to wait for spare parts, this allows me to neatly file the guide + screws in a copy safe and a binder (or in a cardboard filing box together with the rest of the parts) for later reassembly. Hardly any mistake possible...

    I think the caption on the picture is wrong here for 24" iMacs - it says: "On the 24" iMac Intel Model A1225, the bottom center two screws are long (26mm), four on sides (two left, two right) are medium (18mm), and the remaining 6 (four top, two bottom corners) are short (14mm)." I think actually bottom centre two are long, then all the rest are medium apart from the two either side of the CD/DVD drive

    HBloomfield -

    I print out the steps. Get a roll of scotch tape ready. Every screw, or set of screws I remove, I lay on some tape, and then tape them to the number on the directions. Then you have each screw labeled, with direction, and in order, or reassembly. Just working backwards in the directions.

    Barry Coyle -

    I agree with @HBloomfield’s comment overall, but to add to that comment, mine was a little different.

    (2) Long: bottom center

    (4) Medium: bottom left and right; on either side of the CD/DVD drive

    (6) Short: everything else

    Jake Thornberry -

    Yes Jake I found the same with my iMac Model A1225.

    Andy -

    Be careful with the thermal sensor wire so that it won't get under the second bottom screw from the left.

    • La mascherina anteriore è ancora collegata all'iMac mediante il cavo del microfono.

    • Sollevare delicatamente la mascherina dal bordo superiore, lontano dal case posteriore.

    • Dopo aver rimosso il bordo superiore della mascherina anteriore dal case posteriore, ruotare la mascherina verso la staffa ed estrarla dal case posteriore.

    • Ruotare la mascherina anteriore lontano dal resto del dispositivo e adagiarla sul bordo superiore dell'iMac.

    • Per la reinstallazione della mascherina anteriore, iniziare dal bordo inferiore e verificare che sia allineata con il case posteriore prima di poggiare il bordo superiore sull'iMac.

    Contrary to the pictures, to lift the front bezel off, start at top of the computer screen lifting up while apply a little bit of pressure to the foam in the upper corners of the screen. This will give you the leverage needed to get the bezel to lift up. Be careful to not pull to fast, as the camera cable is still attached.

    you'll need to add this step in all the other tutorials about iMac 20" EMC 2210, where it is missing ; they all jump from step 5 to step 6, which is a little annoying...

    Easy way to remove bezel, insert the longest screws a quarter turn into the two top most edge screw slots. Use the screws as anchors to press against as you pull the bezel toward you. Then a simple twist to remove the screws, and the rest of the bezel comes off easy.

    • Scollegare il connettore del cavo del microfono, rimuovendo il nastro secondo necessità.

    • Affinché la mascherina anteriore sia posizionata correttamente, verificare di aver inserito il connettore nello spazio vuoto accanto alla scheda della fotocamera.

    During reinstallation of the LCD panel, be sure that the iSight microphone cable does not become trapped behind the panel.

    I actually didn't have to remove the cable. With the iMac laying on its back, just rotate the front bezel (bottom edge rotating around top edge) so that it's laying upside down, above the iMac. When reassembling, just rotate back into place.

Conclusione

Per riassemblare il dispositivo, seguire queste istruzioni in ordine inverso.
