iMac Intel 21.5" EMC 2308 Display Replacement

Remove the LCD to access most of your iMac's internals.

Edit Step 1 Glass Panel  ¶

Edit Step 1 Glass Panel  ¶ 

  • Before beginning, unplug your iMac and lay it on a soft surface as shown.

  • Stick a suction cup near each of the two top corners of the glass panel.

  • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

  • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

Edit Step 2  ¶

Edit Step 2  ¶ 

  • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

  • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

  • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

Edit Step 3 Display  ¶

  • The last two pictures are detail shots of each side of the display.

Edit Step 4  ¶

Edit Step 4  ¶ 

  • Slightly lift the top edge of the display out of the outer case.

  • Do not lift it too much. There are several cables attaching the display to the logic board.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • Pull the vertical sync ribbon cable out of its socket on the LED driver board near the top left corner of your iMac.

  • The vertical sync ribbon cable has a ZIF style end, but the socket has no lock or retaining flap. Simply pull the cable away from its socket toward the optical drive side of the iMac to disconnect it from the LED driver board.

Edit Step 6  ¶

Edit Step 6  ¶ 

  • Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.

  • Disconnect the LED backlight power cable by depressing the locking mechanism while pulling the connector away from its socket (toward the bottom edge of the iMac).

Edit Step 7  ¶

Edit Step 7  ¶ 

  • Squeeze the two display data cable connector arms together to unlock it from its socket on the logic board.

  • Pull the display data cable connector away from its socket on the logic board.

Edit Step 8  ¶

Edit Step 8  ¶ 

  • Disconnect the LCD thermal sensor cable connector from its socket on the logic board.

  • If your fan is spinning full speed after completion, check this connection or the hard drive's thermal sensor cable.

Edit Step 9  ¶

Edit Step 9  ¶ 

  • Carefully pull the display toward the top edge of your iMac and lift it out of the outer case, minding any cables that may get caught.

To reassemble your device, follow these instructions in reverse order.

Im sorry to say, If it sparked when you touched it your motherboard s now fried. You need a new one.

Robert Wacker,

Very easy to lift the glass out. Don't jerk too hard.

Success replacing the stock ST31000528AS with a STBD3000100 (Dead 1TB to new 3TB, both Seagate). First try. Using another Mac and a quality Firewire 800 cable, I formatted it using Target Disk mode, 2 partitions (defaults, except I made the first one bigger than the second). To the second, smaller one, I copied a bootable Install OS X Mavericks partition. Tried to boot. It booted, and I installed; nary a glitch. (Running the Installer over Firewire would have been faster, but I didn't want to reboot this machine.)

See part 2 below...

(Part 2:)

I SKIPPED steps 6, 7 AND 8! Instead, after doing Step 5, I noticed I then had enough room and cable length to access the screws in Step 11 if I lifted the LCD up an inch or so, rotated it about 20-30 degrees clockwise and moved it a couple inches toward the base, and put it down. After removing them (Step 11), I propped up the LCD (with a spare spudger) and had enough room to do Steps 12, 13, and 14 without much difficulty. Felt safer/less work and risk than not skipping steps 6-8. No risk of the damage Ersan and Michael caused performing Step 7!

Matthew Elvey,

I just edited that step to add a note about the shortcut.

Matthew Elvey,

What the ???

Geoff Wacker has REJECTED my edit: https://www.ifixit.com/Guide/history/ste...

I wonder why. What's the deal, Geoff? I mean I'd understand if I suggested folks didn't need the suction cups, as that could cut into iFixit's income stream, but what's wrong with suggesting that a few steps aren't needed? It worked for me; the EMC 2389 I fixed is humming along with a new 3TB HD I installed while skipping those steps.

Matthew Elvey,

I did not have to remove a single cable! After undoing the torx screws from the sides, I was able to rotate the LCD out of the way enough to reach all the screws holding in the ODD bracket. One of them was a bit challenging to get to, but I never felt that I was risking the cables by leaving them connected. Also, it wasn't totally clear, but you have to actually remove the ODD itself from the ODD bracket - 4 torx screws. The SDD mounts into the hard drive enclosure, then the enclosure is screwed into the bracket. Those holes (enclosure <-> Bracket) did not line up correctly for me, and I had to go with only three of them connected in the end. Seems to work fine.

Another comment on DATA & LCD Temp. Sensor cables: I had to remove the vertical sync, and the backlight cable, however, if you have an assistant or/can carefully rotate the screen clockwise/and then have it held up about 5" to 6" at a slight angle, you do not need to remove LCD data cable or LCD thermal cable, however - IMPORTANT: you must have a second pair of hands/or way to securely prop up the LCD. Also, don't rotate too much, since then you will pull out LCD data cable, and it renders the whole exercise moot, or can damage the cable or connector.

You don't need suction cups. The screen, held by magnets, can simply be pried off using a very thin blade such as a screw driver and fingers.

in Step 7, my connector (new 21.5 iMac - Dec 2010) was not attached that way and just came of easily.

Aperte as duas exibição do conector do cabo de dados braços juntos para desbloqueá-lo de seu soquete na placa lógica.
