Edit Step 1 Display Assembly  ¶ 

  • If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.

  • Lay overlapping strips of clear packing tape over the iPad's display until the whole face is covered.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

  • Do your best to follow the rest of the guide as described. However, once the glass is broken, it will likely continue to crack as you work, and you may need to use a metal prying tool to scoop the glass out.

  • Wear safety glasses to protect your eyes, and be careful not to damage the LCD screen.

Edit Step 2  ¶

Edit Step 2  ¶ 

  • The iPad shown in the photos may look slightly different from your iPad, but the procedure is the same.

  • Insert a metal spudger between the right edge of the display assembly and the rear panel assembly.

  • Rotate the spudger away from you to release the tabs along the top edge of the display.

Edit Step 3  ¶

Edit Step 4  ¶ 

  • Continue prying the display assembly away from the rear panel along the bottom and left edges of the iPad.

Edit Step 5  ¶

  • Lift the display assembly away from the rear panel assembly by its bottom edge.

  • Do not excessively lift the display assembly off the rest of the iPad, as a fragile antenna cable with very little slack still connects the two components.

Ok, a word of caution that can't be overstated. The off screen switch, the lock swith, and the volume switch can all be broken easily. I would stay away from this area completely. The bracket on the off switch is tack welded and can be broken. The volume/lock swith can be malformed to become unusable. So avoid the area and you will be better off.

Most of the spring clips mounted to the digitizer panel (sandwitched between the LCD display mount tabs and digitizer frame) are guaranteed to break. I recommend just purchasing a set (I found on one Amazon for less then $6). With that said, even though I broke most of mine while removing the glass panel/frame assembly, I was able to remount the glass. It seems fairly secure, but I'm going to put the iPad (3G/Wifi) in a case, anyway.

Pas besoin de pistolet a chaleur, il faut juste faire sauter les clips qui maintiennent l'ensemble écran et LCD. Bien commencer par la droite, car se sont juste des picots en plastique a faire sauter par dessus le rebord en alu, puis soulever la partie du bas en cassant les 4 clips ( pas moyen de les garder entier). Ensuite la partie gauche (avec 6 clips) se détachera facilement. La partie haute n'est pas éclipser mais retenus par un cable.

Be very careful as the left side has plastic pins that go into the cover, the right side and bottom have metal clips which break easily.

After unlocking the left side, pull away from the right side, as to save the metal clips.

During reassembly, it can be difficult to get the clips back into the body. I found that I had to put two (sturdy) metal spudgers on either side of the lower-right clip in order to gain enough space to get the clip into the body. Even then it required a fair amount of force (obviously not so much as to damage the display).

There are four black angle metal foil corner pieces that just fall out of the case. They are about 4 mm long and 2mm on each leg. Have no clue what they do or where they go.

That's probably broken Metal Display Clips. Easy to replace, but you'll need to purchase a set of new clips. Luckily, they're not expensive :-)

orb,

The display data cable may be glued into place along the right and top side of the right battery. You should use an iPod opening tool to pry it away from the adhesive. This will allow you to get a wider opening between the display and iPad body in order to access and remove other cables.

Whats this antenna for? What is I accidentally tore it out? what will it affect?

Laith, · Reply

This is the GSM antenna cable connector.

orb,

did u find out what it did as I pulled the whole connector socket off can this be repaired

dods,

The antenna cable is easily broken when separating the screen from body.

The whole antenna can be purchased for about $5 new on eBay.
