Introduction
This guide shows you how to replace the all-in-one Display and MagSafe cable of your Apple Thunderbolt Display.
What you need
-
-
Lay down the display with screen side up.
-
Place the two suction cups on both sides of the top of the screen and make sure to lock them in place.
-
The glass screen is connected to the rest of the display by small magnets. Lift slowly and the screen will come right off.
-
-
-
-
You should now see the EMI filter right in the middle of the device (although held in by a few other components).
-
Follow the wires coming out of the bottom of the Power adapter off to the left.
-
Take the tweezers and remove the piece of tape holding the wires to the casing.
-
There is only one connector that needs to be taken out (even though there are two right next to each other!).
-
Grab the connector from the bottom and pull it carefully from its corresponding socket.
-
-
-
The EMI filter is connected by three screws. Use the T10 screwdriver to remove them.
-
The screw that holds in both the filter and a wire that is connected to it is a different size and should be kept identifiable from the other two screws.
-
The green and yellow wire that was held in by the different screw is tucked behind another component. To get it out, squeeze it behind the black wire and the filter will be able to be removed from the casing.
-
-
-
Remove the two T10 screws from the metal plate holding the cable in place.
-
Remove the metal plate.
-
To reassemble your device, follow these instructions in reverse order.

Unbelievable amount of very detailed and careful work to replace a Thunderbolt cable which is attached on the inside to a standard Thunderbolt socket! Why not just have the socket on the back of the unit?????
You can actually use the socket on the back of the unit as an input if your octopus cable is dying, as long as you are connecting directly to a Thunderbolt 1 or 2 Mac. If you are using the Thunderbolt-3-to-Thunderbolt-2 adapter, you have to use the built-in cable.

In reply to Tim - This is not true - I am running a 2018 Mac Mini using the Thunderbolt 3 to Thunderbolt 2 adaptor and a standard Thunderbolt 2 cable connected to the external thunderbolt connector on the Thunderbolt Display - It works fine.
Me as well. Was dreading the repair until I plugged a spare Thunderbolt 2 cable from a Thunderbolt 3 (to 2) adapter to the back of the display. Thanks!
