Screen replacement -- can I do this myself?

When opening the screen, you need to be careful of a few things to avoid cutting cables. Such as the power button and volume button cables. These are located at the top right and usually the cable is sometimes touching the glass or even sticking to the adhesive. When prying the top right of the iPad make sure you don't use your prying too much in or you'll risk cutting the cable.

There is also a wifi antenna that has adhesive on top of it. You need to make sure you don't cut the antenna and when lifting up that area, the wifi-antenna will be stuck on to the glass at times and you will need to separate it with a prying tool.

When unplugging the iPad digitizer ribbon cable, make sure you don't use a metal prying tool and use a plastic one instead to lift up the clips that hold it in place. As doing this can short the logic board. You can lift up the clips with your hand but be gentle with them.

Is the housing of the iPad dented in any way especially at the corner bezels of the iPad? If it is dented too badly it will be hard to put the new digitizer on as dents may cause it not to sit properly causing the glass to push up. You will need to straighten these dents to get the digitizer to sit flush with the iPad.

It will be easier to open if you heat up the glass. Depending on how much cracked the glass is, the less it is cracked the easier it will be to lift up and separate the glass as there's less glass fragments to take off.
