Introduction

A touchscreen that is broken or damaged can prevent access to applications on a device, which can make the device useless. This guide highlights how to remove the back cover and front cover of the tablet in order to get to the touchscreen as a means to replace it.

Parts

No parts required.

Make sure the device is turned off before attempting to disassemble it.
  • Make sure the device is turned off before attempting to disassemble it.

  • At the top portion of the memory card slot, use the small metal spudger to create separation between the back cover and the rest of the device.

  • The small metal spudger is only used to create separation between the back cover and the rest of the device, not to remove the back cover.

Why can I use instead of the spudger

Use the intermediate metal spudger in place of the small metal spudger to remove the back cover. This is done by sliding the intermediate metal spudger around the perimeter of the device, beginning at the top portion of the memory card slot. The second picture shows the internal portion of the device once the back cover is removed.

Use the spudger to disconnect the touchscreen from the motherboard. The two are connected at the top half of the motherboard where the yellow rubber portion of the touchscreen is located. The first and second pictures illustrate the touchscreen when it connected and disconnected, respectively.

Use the spudger to separate the touch screen from the front cover of the device. The touch screen is glued onto the front cover, so this step in the process requires patience and a fair amount of strength.

  • The touch screen is glued onto the front cover, so this step in the process requires patience and a fair amount of strength.

  • The top and bottom portions of the touch screen are more reinforced with glue than the other sections, so extra force will be required.

  • It is recommended to push inwards from the sides using the spudger to separate the top and bottom section from the front cover.

Don't let either of these happen to you:

I was not careful enough at this step. At the top left of the screen, near the digitizer's flex cable, I allowed my spudger to go between the glass and the digitizer film, rather than between the film and the LCD. This left a mark quite as bad as if I had broken the glass. To avoid it in future, I will use heat to loosen the adhesive and then keep the spudger near the very outer edge of the screen in this area, to avoid the flex cable's attachment point.

At the bottom right corner, I was simply too vigorous, and broke the glass. The adhesive is very strong. In future I will always loosen it with heat (a hot air gun or an iOpener heating pad) before removal. In fact, I plan to reapply heat to each area I'm working on as I go--just enough so that the glass is quite hot to the touch.

(I have pictures, but don't see how to attach them…moderator?)

I also don’t see how the screen can come apart from the frame and the lcd as easily as is shown in the photos. My lcd came up with my screen and in the end I had to disconnect the lcd and take both the screen and the lcd out together. Now I have to order a replacement lcd to put with the digitiser screen that I purchased and install them together.

Once the touchscreen is loose enough, slowly pull it off the front cover to fully remove it from the rest of the device. Avoid pulling the touchscreen off too quickly as this could result in damaging or even breaking the touchscreen. This could result in damaging the touchscreen connector in the back of the device.

These steps worked well but you must use a metal spudger to get this started. I didn't have one and it was a nightmare. I finished the project but it was very difficult to start. I would also use a heat gun to loosen the glue for the bottom and top. Just my opinion from my experience.

See comments on the last step re: avoiding the area of the flex connector, and using heat, as the previous commenter suggested, throughout the removal process to loosen the adhesive and avoid breaking the glass.

Also, the “metal" frame around the digitizer is very susceptible to being dented. Be very careful of it.

Finally, a piece of advice from other iFixit commenters about cleaning the LCD before adding new glass: careful circular motions with a very clean, dry microfiber cloth are sufficient in most cases. If not, a small amount of water can be added to the cloth. Avoid adding alcohol or water directly to the LCD, as it is easily smudged.

Oops--one final suggestion, also from other iFixit commenters (I can't find the original, or I’d reference it. It's in the Q&A section, answering a question about jumpy digitizer responses after screen replacement.)

The first time I did this, all seemed well until I tried to use the digitizer, when its response to touch was suddenly very jumpy and erratic in all areas of the screen. The next time I followed Ifixit advice and covered all metallic-looking areas of the back of the new screen with thin Kapton tape, and had no problems. I essentially made a thin frame of Kapton all the way around the non-transparent areas of the screen.

There have been various suggestions about why this might work, most speculating on small electrical shorts occurring between these metallic areas and the metal parts of the frame surrounding the LCD. I just know that it's quick and easy and seems to work.
