LCD was damaged on iPad 3. I was getting a greyed out screen, the digitizer still worked as I could tell the screen was responding.
The repair went great! It took me an hour and I followed the step by step guide here on iFixit. The iOpener worked without a hitch, it is a must have if you are going to attempt this repair.
The best advice I can give is to take your time and reheat the iOpener as needed. You might get frustrated trying to find the adhesive exploit but it is there. Use the plastic tools provided don't be tempted to use anything metal! The picks work like a charm and the right size for this type of repair. Work around slowly and you will get the correct results.
