How to replace I pad 2 broken screen

Apple charges anywhere from $199 to $599 (plus tax) to fix a broken iPad screen, depending on the model. You can try from the amazon or ebay to get a replacement for less and get it done from your local repair guy for less.

Just look for genuine items as the local ones come with no warranty and color accuracy isn't there to match with apple's color gamut.

Is the screen broken or is it just the digitiser? There are many excellent videos available which take you through the process of replacing all parts of your iPad.

However, it is not something that can be fixed easily and you need to exercise great patience in dismantling your broken iPad and replacing the damaged parts.

Make sure you have plenty of space in which to work and place all the parts of the iPad around your working area so they are easy to reach.

Good Luck.
