Follow this guide to replace the left speaker on a Microsoft Surface Pro 7.
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.
Wear safety glasses to protect your eyes, and be careful not to damage the LCD screen.
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 Surface’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.
Completely power off the Surface before you begin disassembly.
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.
A hair dryer or heat gun may also be used for more heat, but be careful not to overheat the Surface—the screen and internal battery are susceptible to heat damage.
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 do not 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.
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.
Reheat your iOpener and apply it to the bottom 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.
A hair dryer or heat gun may also be used for more heat, but be careful not to overheat the Surface—the screen and internal battery are susceptible to heat damage.
Reheat your iOpener and apply it to the left 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.
A hair dryer or heat gun may also be used for more heat, but be careful not to overheat the Surface—the screen and internal battery are susceptible to heat damage.
Insert a new opening pick into the bottom left corner and slide it around the corner toward the left edge.
Be careful cutting under the lower 2.5 inches (65 mm) of the left edge. Do not insert the opening pick more than 1/8 inch (3 mm) here. The display cables sit near this part of the bezel and are easily damaged. Once past the display cable area, do not insert the pick past the bezel.
Slide the pick along the left edge of the Surface to cut through the screen adhesive.
Leave this pick in the left edge to prevent the adhesive from resealing.
Reheat your iOpener and apply it to the left edge of the Surface's screen for two minutes.
The adhesive is thickest along this edge, and you may need to reheat and reapply the iOpener several times to get the tablet warm enough. Follow the iOpener instructions to avoid overheating.
A hair dryer or heat gun may also be used for more heat, but be careful not to overheat the Surface—the screen and internal battery are susceptible to heat damage.
Round the left corner with the opening pick and slide it along the top edge of the Surface. Stop when the pick is 2.75 inches (70 mm) away from the left edge.
The next 6 inches (15 cm) of the top edge of the case is covered by the left and right antennas, which sit between the case and the screen bezel. Follow the next steps carefully to avoid damaging the antennas.
Fragile antenna cables lie under the top edge of the screen. Carefully follow the procedure to avoid damaging them.
Insert the point of a pick under the display where you just stopped cutting. Do not insert the pick deeper than the edge of the bezel.
Carefully roll the pick to the right, pressing the long edge of the pick into the screen adhesive underneath the bezel, cutting the adhesive as you go. Do not slide the pick along the edge of the Surface.
Repeat this motion of inserting the point of the pick where you just cut, and rolling to the right all along the top edge of the Surface, until the pick is 2.5 inches (64 mm) from the right edge of the Surface.
Once you cut the adhesive over the antennas (8.5 inches, or 22 cm, from the left edge), slide the pick the rest of the way along the top edge of the surface and round the top right corner to slice through any remaining adhesive.
Notice the small arrows surrounding the perimeter of the motherboard EMI shield. These mark the locations of each clip securing the shield to the motherboard.
During reassembly, press down on each of these arrows to make sure the clips are secured.
Be careful not to puncture or deform the battery with your opening tool.
Starting with the clips adjacent to the battery, use an opening tool to carefully pry the motherboard EMI shield straight up from underneath each arrow to disconnect the clips.
Take care to deform the EMI shield as little as possible. It will need to be reused.
Gently slide the flat end of a spudger between the speaker wires and the motherboard until it is resting against the connector.
Carefully pry straight up on the connector to disconnect it from the motherboard.
Be gentle—the speaker wires are delicate.
During reassembly, place the new speaker wire harness on top of the connector on the motherboard and gently press it straight down with your finger to reconnect it.
Once all of the buttons are separated from the speaker, gently slide an opening pick under the rest of the ribbon cables to separate them from the speaker.
The ribbon cables are secured to the speaker with light adhesive.
The ribbon cables are fragile; be careful not to tear them.
Remove the power and volume button cable from the old speaker and transfer it to the new one.
During reassembly, place the holes in the button cables over the pegs on the speaker to ensure proper alignment. Reuse existing adhesive if possible. If new adhesive is necessary, use thin double-sided tape such as Tesa tape.
