iMac Intel 21,5" EMC 2308 Bluetooth Karte austauschen

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.

Nails worked for me too

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 use Garmin GPS suction cup. Work very well

I’ve just successfully installed a 1TB SSD in place of my optical drive thanks to the information here- thank you to everyone who has contributed!

3 comments- the procedure described here seems to vary between HD replacement and dual HD/optical drive replacement. This can be confusing at times.

Expect there to be minor differences between the layout described and what you find when you open up your iMac. There are also, surprisingly, differences between the HD enclosure description, and the article provided by ifixit.

I was able to replace the DVD/HD enclosure single-handedly without fully removing the LCD, or deconnecting any of the cables (steps 5-11). It’s a bit cramped, and fiddly, but I was not happy removing any of the cables despite watching videos, etc., since they all seemed to involve applying more force than I was comfortable with. A more detailed description of how to release them might have helped, but even here, there may be minor variations even within the 2389 model.

Good luck!

I did it several times with one suction cup at the end of a kitchen brush. Once with the blade of a swiss army knive, also ok. And i’m pretty sure it works with fingernails too

Fingernails are all you need to free the glass from its magnetic hold. If you don’t have them, slip something thin and plastic, like a spudger, at a top corner.

Check for chips in the glass BEFORE you do this step. If there is a chip when you pull up with the suction cups you will wind up with a jagged mess. If you do have a chip I would advise covering the screen near the chip with clear tape of some kind before lifting out. Mine shattered right at the chip and the resulting glass dust cloud got all over. My solution was buying a new glass screen.

A short piece of small gauge vinyl tubing that fits tightly over the head of the T-10 driver leaving an 8th of an inch or so in which to insert the screw to engage the head will hold the screw long enough to keep it away from the magnet and get it going in the hole.

I use non magnetic SS curved tip tweezers together with a magnetized #10 torx bit both to remove and reinstall the screws. You can magnetize and demagnetize the bit using the strong magnets on the LCD frame. Don't worry too much during removal, you can recover the screw. But loath the moment you drop the last screw during reassembly. For that reason, reinstall the screws near the magnets and hardest to get to first.

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

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.

Any ideas where to replace this cable?

I followed Suzanne’s comment and also did not disconnect this cable (vertical sync ribbon cable) to avoid damage. I pivoted the screen about 110 degrees after the other cables where detached. On a flat surface, this is easily done and the cable is not tight. Image of my angle if I can drop a link. and cable in this position not in tension.

Where can I buy the replacement for this vertical sync replacement cable?

I feel pretty silly. I spent wayyyy too long trying to get these cables disconnected. Happy I found this guide; hopefully, I won't struggle with such simple things since you provide pretty good details! Thanks.

Pas beaucoup de place pour déconnecter ce cable ! En essayant d'ouvrir trop l'écran pour passer mes "grosses mains" j'ai cossé le connecteur : je suis dans le caca :-( (et pourtant j'en fait des démontages !) Alors ATTENTION !!!
