Introduction

There is a significant chance that you may break the unreinforced and fragile display panel during this procedure. Be sure to apply adequate heat and be extremely careful while slicing through the adhesive. Wear safety glasses in case the glass shatters.

Applying new thermal paste during reassembly may improve the performance of your Surface. If you wish to do that, make sure you have new thermal paste and either high-concentration isopropyl alcohol or a specialized thermal paste cleaner.

What you need

Step 1

              Tape the screen

If your screen 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 Surface’s screen until the whole face is covered.
This will keep glass shards contained and provide structural integrity when prying and lifting the screen.
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 display.

Step 2

              Heat the right edge of the screen

Heat an iOpener and apply it to the right edge of the Surface’s screen for two minutes.
You may need to reheat and reapply the iOpener several times to get the tablet warm enough. Follow the iOpener instructions to avoid overheating.
You may also use a hair dryer, heat gun, or hot plate to heat the Surface.
Be careful not to overheat the Surface—the screen and internal battery are susceptible to heat damage.
Don’t use a hot plate if the screen has been taped.

Step 3

              Take note of the adhesive layout

Take note of the screen adhesive layout before continuing:
These areas only contain adhesive and are safe to cut.
The display board and flex cables sit here close to the edge. Cut carefully and don’t insert the pick more than 1/8 inch (3 mm).
Fragile antenna cables lie under this part of the screen. Carefully follow the procedure in step 13 to avoid damaging them. The adhesive is also the thickest here.

Step 4

              Insert an opening pick into the speaker opening

Insert an opening pick into the top-right speaker cutout on the screen and slide the pick between the glass and speaker grille.
Don’t insert the opening pick deeper than 0.45 in (12 mm). Inserting the pick too far may damage the LCD.

Step 6

              Cut through the screen adhesive

Slide the pick down the right edge of the Surface to slice through the adhesive under the screen.
Throughout the rest of the procedure, if you encounter significant resistance while sliding the pick, stop and reheat the section you’re working on. Applying too much pressure with the pick can crack the glass.
Leave this opening pick in the right edge to prevent the adhesive from resealing.

Step 15

              Open the Surface

Very slowly lift the screen assembly away from the Surface case. If you encounter any resistance, stop and check that all the adhesive is separated.
Don’t remove the screen yet. It is still connected to the motherboard by two cables.
Use an opening pick to cut through any remaining adhesive.

Step 17

              Tip for removing EMI shields

Use this method to remove any EMI shields necessary during your repair:
Use one tip of a pair of angled tweezers to pry up the EMI shield from the gaps between the “teeth.”
Repeat this procedure at different points around the perimeter of the shield until it is free.
Try not to deform the shields too much—you will need to reinstall them during reassembly.
To reinstall, correct any deformations to the best of your ability, make sure the “teeth” align with the rim on the motherboard, and press down on the entire perimeter of the EMI shield.
Make sure all “teeth” are snug to the metal rim and not bent underneath the EMI shield.
