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  ¶

Edit Step 10 Optical Drive  ¶ 

  • From here, the repair will be easier if you flip the computer around so the base is facing you.

  • Remove the following four screws:

    • One 9.3 mm T10 Torx screw with a large head

    • Three 9.3 mm T10 Torx screws with a normal sized head

Edit Step 11  ¶

Edit Step 12  ¶ 

  • Lift the inner edge of the optical drive and maneuver its connector past the GPU frame attached to the logic board.

  • Carefully pull the optical drive off its mounting pins on the right side of the outer case to gain clearance for disconnecting the optical drive cable.

  • Allow the optical drive to hang down as you de-route the optical drive thermal sensor connector from behind the GPU heat sink.

Edit Step 13  ¶

Edit Step 13  ¶ 

  • Disconnect the optical drive cable by pulling its connector away from the optical drive.

  • Remove the optical drive from the iMac.

Edit Step 14 Optical Drive  ¶

Edit Step 14 Optical Drive  ¶ 

  • It is not necessary to peel all of the EMI tape off the optical drive bracket. Only peel up the portion highlighted in red that is attached to the body of the optical drive.

  • Peel back the portion of aluminum tape highlighted in red, leaving the rest attached to the black plastic optical drive bracket.

Edit Step 15  ¶

Edit Step 16  ¶ 

  • If necessary, use the tip of a spudger to press each of the optical drive bracket tabs out of their slots on the bottom of the optical drive.

  • Rotate the optical drive bracket slightly away from the optical drive.

  • Pull the optical drive bracket away from the open end of the optical drive, minding any tabs that may get caught.

Edit Step 17  ¶

Edit Step 17  ¶ 

  • Use the tip of a spudger to peel back the piece of foam tape covering the optical drive thermal sensor.

  • Use the flat end of a spudger to carefully pry the thermal sensor up off the adhesive securing it to the optical drive.

  • If you have a disk or anything else stuck inside your optical drive, we have a guide to fix it.

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.

The metal near the screws is VERY magnetic. Honestly, the hardest and by far most frustrating step was trying to put these screws back in.

seancourtney, · Reply

I ran into the same problem - easily the most frustrating part of this process. To help deal with it, I took a drinking straw, cut it to be about 2 inches long, and used it as a chute to guide the screw to the hole. Dropping the screw down the straw, it'd still stick to the side due to the magnets, but using my screwdriver, it was easy to push the screw down to where it needed to go, and the straw kept the screw from being pulled out of place by the magnets.

josh,

You can use one hand to hold the edge up while reaching with the other hand to disconnect cables. You may want to have a prop handy (like a small book) or an extra person to hold the edge up while you disconnect cables.

I am having a difficult time reattaching the LCD cable. A better description or any tips would be useful here.

When putting the display down on the table, be careful not to kink the flat ribbon cable.

The replacement hard drive I used doesn't even appear to spin up and the Time Capsule restore process doesn't show it as available. It just stays at Searching for disks and never finds it.

I had to use Disk Utility to partition the drive and then it showed fine. Rookie mistake.

JRBv3,

In my case the red screw was on the lower left side near the power-data cable!

Can you (re)use this exact thermal sensor on the optical drive and attach it to a new SSD?
