Introdução

Guia tipo pré-requisito exclusivo para desconectar os cabos da tela de um iMac 21,5" com tela Retina 4K do final de 2015.

Ferramentas

Tweezers

Passo 1

Erga a tela o suficiente para facilitar o acesso ao conector, mas não tanto que os cabos fiquem estendidos e as suas conexões sejam danificadas (umas 8").
Segure a tela com uma mão enquanto usa a outra mão para desconectar o cabo de alimentação da tela.

It was difficult to remove this connection. I ended up having to gently pull-up vertically a little on the wire side to unsnap it about 1mm and then horizontally wiggle it out.

I had a difficult time removing this connection. I had to lift the wire-side about 1mm before it unsnapped and then carefully wiggle it out horizontally.

Can this cable be replaced? I am worried mine is damaged. I have no display after the screen fell and stressed the display flex cables following an SSD upgrade.

This step should be done with extreme caution and care, as this step 19 is not described in great detail (sorry, author).

The first (most outward) cable will slide out by gently pulling it by its tabs. The second (inner) cable is more tricky, as the locking lever must be moved backward first, before gently pulling backward on the cable connector. The angled tweezers are useful here, to help lift that locking lever, because fingers are too big for this.

be VERY careful and SLOW...take your time. These displays crack VERY easily when removing and they'll spider web on you. I've done probably 20 or so of these and cracked 3 being super careful.....ugh.

I found the best way to unplug this display power cable was to use my right hand, and the fingernails of my index finger and thumb to grab the ends of the tabs on either side of the connector, squeeze, and pull the connector out gently.

Phil McInnis -

i think the cable nearest the case edge is held in by friction and can be gently pulled, maybe with fingernails or a spudger. The next cable is held by a wire lever clip as described above it unlocks so the cable can be removed. These cables are also fiddly to re-insert, I didn't get one of them home and had no display after power-up, so at the end, don't re-seal the screen until tested.

I suspect I broken either the video or the power connector when I opened it the iMac. What can be done / price to have the logic board fixed? Also where?

Passo 2

Ainda apoiando a tela com uma mão, vire para cima o suporte metálico com trava do cabo de dados da tela.
Cuidadosamente, puxe o cabo de dados da tela de seu soquete na placa lógica.
Certifique-se de puxar em linha reta o conector do cabo de dados da tela para fora do soquete, mantendo-o paralelo à placa-mãe, para evitar causar danos a ele.

Cannot seem to find a replacement cable for this, as I suspect mine is damaged. Can’t even find a part number. Anyone know what it might be?

That's the part I ordered for mine and it seems to work ok. I did make a point of contacting the seller and advising them of my requirement and they ensured I got the right part and it matches the description of the link. Bear in mind I bear no responsibility if yours does not work since I am just sharing what I did and what I ordered. Thanks.

Jim Stanford -

I also need that cable.

It's a little difficult to tell... but looking at the connection to the logic board on the video data cable, are the pins faced up or down?

On the display, same question since it appears you have to "twist" the cable during the reconnection step.

For this particular cable, take a good look before pulling on anything. Plug is locked on its socket with a bracket. You can lift this bracket by holding the small, flat black plastic handle that is attached to it. If you're struggling to grab it, use the end of the pizza roller handle to lift it, or the tweezers. Cable then comes off by pulling parallel to the main board.

How can I tell if either of this cable is bad? My iMac display won't turn on after reconnecting it. I'm using an external display and everything is working except for the iMac display. If I go to settings - display the built-in display is recognize. But again nothing shows up in the screen - not even the apple logo when turning it on.
