Display removal after new screen just fitted. Any tips? Tape sticky!

It can be scary! As you don’t want to damage your display.

I’m surprised you are encountering an issue here as the cut tapes should split as the foam core is designed so it can break apart.

What I’ve also faced is people using Tesa tape which doesn’t have a foam core and is a bear to get the display off when its used. I charge an additional $80 if I encounter that as it takes me a good 45 mins to an hour extra to get the display off. First follow this guide to the letter and using the tools listed! iMac Intel 27" Retina 5K Display Display Replacement

• Don’t forget to get the iMac Intel 27" (2012-2019) Adhesive Strips you may want to get two sets just in case! Before you start.

OK, so how do I do it when the wrong adhesive is used? Or, in your case over sticky.

Lets look at a similar technique Using feathers and wedges While you may laugh how a stone cutter splits a stone into clean slabs. The basic idea is sound here as well! Instead of feathers and wedges we will need to use a ton of picks and cards.

We need to go slow and it’s not going deep its creating and maintaining a gap thats the key! I use about eight cards and sixteen picks to do the job

I use Blue masking tape to hold the edges as I go around. Remember once you have a gap you want to enlarge it ,you don’t want a wide gap as the stress can damage the display! Its the linear gap we need to create. Once the top is loose, slowly tilt the display forward to release the bottom edge.

Make sure you’ve cleaned off the old adhesive and tape so the surfaces are clean. Don’t lift the black tape! I use Goof Off and reagent grade 90% isopropyl alcohol as I don’t want any junk left which interferes with the tapes adhesion.

I use a heat gun to warm the case and the glass (not hot, warm!) and I use a rubber J roller to help press the glass down around the edge as Apple recommends.
