how to repair lcd and glass cracks on the iMac 27 A1419
If you're using an iMac 27 inch and the fans are noisy, or if your iMac gets hot, you might need to replace it with a fan replacement.
When replacing the fan of a thin iMac, it is necessary to remove the LCD, but unlike the previous iMac, it has become difficult to disassemble.
You can check how to change the fan by the following decomposition method, but if you are not confident in the disassembly, it is recommended that you consult a repair shop.
Please note that if you break the liquid crystal in the middle of disassembly by any chance, the expense of tens of thousands of yen will be added.

The flat iMac LCD is not threaded, but is attached to the main unit with very powerful double-sided tape.
How to peel off is to tear off the liquid crystal by inserting the tool into the gap between the liquid crystal and the main body as shown in the image, but this work is required even in the case of fan exchange, iMac 27 I feel that the decomposition of a1419 has become a higher hurdle than the previous model.
I think that there is something that can be substituted in addition to the tool of the image, but the tool of the image is very easy to use because it is a roller type.
I think that it is per playing cards as a substitute, but it is not possible to insert it into the gap if it is not a fairly thin thing.

Double-sided tape is attached to one lap of the liquid crystal, but the place where the tool is inserted is all right and left.
The lower side peels off without permission by the weight when opening the liquid crystal later.

On top, you can float the liquid crystal a little as in the image when tearing the left and right double-sided tape, but please be careful because I think that there is a cable on the back of the liquid crystal when you look inside.

There are two cables on the back of the LCD, but first it is removed from the cable on the right side that you looked into.
It is how to remove the cable, but it has become possible to remove it easily if it pulls it upward as it is.

This is the golden connector on the left side, but don't pull it out as it is.
There is a hook of "co-shaped", so let's pull out the cable itself after raising the hook with the nail.
Now that you can remove all the cable connections, let's remove the liquid crystal while slowly pulling it back to the front as it is.

Only the liquid crystal was able to be removed.
There is a considerable weight because the glass and the liquid crystal panel are integrated and there is 27 inches.
Please keep the liquid crystal in order not to use it for the time being.

I think that it is possible to check a large fan in the middle when the liquid crystal is removed, but let's remove the connector of the arrow part first.
The connector can be easily removed if it is lifted upward.

The fan is secured to the main body, but remove all three red-circled screws.

The iMac27 A1419 fan could be removed.
The fan is not a part that breaks down very much, but it may break down if dust is clogged.
In the case of A1419, cleaning is also difficult because no screws are used for the exterior, but it is recommended that you check it if you think that it will have heat or the fan will not rotate.
