简介

移除LCD,来让您接触到设备内部元件。

  • 在开始之前,将您的iMac如图所示放倒在柔软的表面上。

  • 在玻璃面板顶部的两个角上放置吸盘。

  • 要使用我们的吸盘时,首先将吸盘的活动手柄扳动到与玻璃面板平行位置。 在吸盘轻轻地吸在玻璃面板上时,扳动活动手柄使其与另外一个手柄平行。

  • 如果您的吸盘无法吸住,尝试使用温和溶剂清洁玻璃面板和吸盘。

Change "Before beginning, unplug your iMac and lay it on a soft surface as shown." to "Lay your iMac on a soft surface as shown"

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.

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.

MaximBorzov - 回复

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.

Deepsurvival - 回复

That's a bad idea. using a metal tool to pry off glass is likely to end with an expensive broken front glass.

Suction cups are common. Find a couple and do it the safe way. I use some cheap ones that came with iPhone repair kit.

Hello, I just need to replace a slightly cracked screen on my iMac. Where is it best to place the suction cups? Thanks in advance

michelemiller0 - 回复

No need for suction cups, I just stuck my nails (short like guys usually have) between the top part of the screen and body, and it came off easily. I've never done it before, so it seems to be very easy.

Just completed the replacement of the optical drive with an SSD using an OWC Data Doubler kit. Attempted to remove the optical drive without disconnecting any cables but found it a bit fiddly to orient the screen for good access. I bit the bullet and disconnected them and found the process less daunting than I imagined. Reconnecting them was similarly straightforward if you're careful.

Tip: you can skip the step for removing the optical drive thermal sensor connector from the motherboard. Still need to remove the sensor from the optical drive but you can leave that hanging and reattach it to the SSD later.

I have an odd question -- I want to remove the polarizer from the LCD. With some monitors this is trivial, others not so much. My question is whether it is bonded to the Liquid crystal, or whether it's loose, or cutting it with a razor blade would remove it. Obviously I'd like to know before I go to the trouble of dismantling the thing... Thanks. Paul

On reassembly, it is REALLY HARD to align those screws, because of the field of the strong magnets that hold the glass cover on. I'm sure there's a trick to it, but I'd love to know what it is for future reference.

Peter Shenkin - 回复

I used needlenose pliers and the T10 to align the screw into the hole. Otherwise the screw keeps jumping to the magnet. And patience with this NON-CAPTIVE screw design (c’mon Apple, even **I** came up with that, and I’m an idiot!)

The vertical sync cable was snug initially and now is loose. I checked and the cable is intact. Has anyone had experience with making it fit better?

Rajan - 回复

Scotch tape on the upper side and sliding this in helped to secure the cable.

Rajan - 回复

Reassembly of this part was the closest I came to disaster on this project. I tried inserting the connector a few times without success, and when I looked it it the leads, which are fragile, were all mangled. I smoothed them out by hand as best I could and and reinserted, very carefully this time. The trick is that the tip of the connector should be pointed somewhat upwards when reconnecting.

I was pretty sure that when I was done, I would reboot but have no display; but fortunately, everything worked.

Peter Shenkin - 回复

Hi, I still have a question. What is the "Job" of the vertical sync ribbon cable. Thanks

Lutz Blum - 回复

So let’s say someone wanted to suck some of the dust off the back of the display before reassembly. Let’s just say that. Someone would likely suck this forsaken cable up into the vacuum tube then, wouldn’t they? They might. And if it were to oscillate in a rushing torrent of air, it might get munged? It might.

Here’s how you overcome such a disaster:

1) cut the end fresh, as close to the end as you can while cutting off any frayed end.

2) abrade the end gently, repeatedly, along the connector wire axis. I used emory paper. Your goal is to expose the copper conductors in the last 1/4” of the fragile evil wire.

3) Tape a small stiff cardstock to the back of the end of the connector. This is essential to press the connector wires into the connector.

4) Gently insert, taking special caution to not peel the copper off of the connector.

5) Tape that connector down deftly, without letting it move a millimeter and securing it for all time.

I just leave it connected. After disconnecting the other cables, there is enough slack to lay the display on its backside if you’re working on a flat surface.

Duane Johnson - 回复

I have replaced the hdd in this model about 8-10 times - I have never had to disconnect any cables other than the sata and temp sensor cables on the hdd. I just prop the lcd up with an egg carton (or something about 3 inches high that is soft and light) and access the hdd that way. The only thing I ever have trouble with are is putting the LCD screws back in around the magnets - but I have pretty much perfected that with a sissor/ tweezer tool.

good morning everyone. I have a problem with my iMac. unfortunately the screen starts to look with horizontal stripes. after verifying that it is not by the graphics card, I bought a led a different model and some connectors are different. He led riding my iMac is lm215wf3 (sl) (a1) and I bought by mistake lm215wf3 (sd) (a1). several problems. the temperature sensor input is different, and led backlightsync also is different.
