I too damaged my display because of this absolute nonsense (The German version, which I used, still had this INCORRECT portion in it). I can't believe how long it took iFixit to update this, even though people have been reporting this for years on end. Sadly iFixit still haven't updated a variety of other things that are still at the very least high risk instructions. I just messaged them the other day, but they don't seem to care about or understand the remaining issues that this guide has. At least they updated one of the most severe things, but they just plainly told me 'I'm wrong' about the rest. I liked iFixit it so far, and I've worked on a variety of (difficult) repairs - but this experience was a very huge let down.

I too thought it was the isopropanol that ruined the screen (even though I made sure it wouldn't go into the screen), but that stuff evaporates pretty quickly anyway. Your screen was most likely damaged just by opening the device with those picks (just like in my case) - a variety of people have reported the same thing. Turns out the instructions are just doing a really bad job at indicating how easy it is to damage the screen, and underestimate the force as well as time and heat required for the whole procedure. The German instructions are even worse. Even though the instructions give a warning, at one point they inexplicably also suggest it's "ok" to shove those picks into the display as far as the display bezel goes. If that's not going to ruin people screens, I don't know what is. And I personally think those "picks" are horrible choice for this repair. I never used them in any of my other repairs, but stupidly decided to work with them this time. This is by far one of the most difficult repairs.

What is iFixit thinking here, labelling this with "medium difficulty"? It's absolutely out of step and others mentioned it already: It is extremely easy to damage the screen of the iPad during this procedure, and the instructions are doing a horrible job indicating how truly difficult the procedure is. I repaired iPhones and Macbooks with the help of iFixit before, and have never damaged anything. But now, thanks to this poor guide, I too, just like others, have damaged the screen of the iPad I worked on. Absolutely disappointing to say the very least. I usually always stray away from using those pointy opening picks. I was stupid enough to use them this time, thanks to this guide, and what did it get me...? To make this even more infuriating, is the fact that new LCD screens come WITHOUT the home button, which you have to swap out from the old device with magnetic sensor flex cable, which requires micro soldering. People complained about this years ago. This's just bad, no no, I'm mailing support about this.
