Introduction

Use the guide to learn how to replace the motherboard for the Bowers and Wilkins T7 Bluetooth Speaker.

As with all electronic devices, make sure your device is powered off before you begin.
Gently lift up the access panel; it should easily "pop" open.

My model does not have screws in the front as indicates here. Not sure what to do now

FYI: I bought the Ifixit toolkit and sadly the screw driver isn’t long enough to remove the 4 middle screws.

What sizes are the screws exactly? I took mine apart and someone threw out the screws so now I need replacements.

Be gentle, the rubber seal is fragile and easy to tear, resulting in cosmetic damage to your device.
Using the ifixit Opening Tool, carefully pry off the rubber seal around the sides.
The seal is held by adhesive, if this is proving difficult you can use a heat gun to help the process.

The cover is the most difficult part to remove. As you work, pry continuously, moving the tool around the device, working it a little further as you go.
Using the ifixit Opening Tool, pry open at the seam found under the rubber seal.
As the cover starts to come off, you can lift up using your hand.

I tried this with the ifixit tool, but I could not remove the cover

I used a sharp knife. Note carefully where the seam is in the above diagram: on the back about 7 mm from the edge.

Gently squeeze the internal locking mechanism inside the red and white terminals with either your fingers or a pair of precision tweezers.
While squeezing the internal locking mechanism, pull back the terminal.
Repeat this process for the second speaker.

Ensure you position your fingers, or a screwdriver tool with the 0.8 tip, in a position on the outside of the black tab.
It is advisable to use a nylon spudger to accomplish this task, because using a metal screwdriver like the one used in the image, can be unnecessarily dangerous around delicate connectors and the motherboard in general.
When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage.
Slide the black tab out so the cable is able to be removed.
At this point, the cable is removed.
These ports are difficult, as you need to simultaneously push the black tab while pulling the cable.

Use the 0.8 and 1.0 screwdriver tips to press on the pins to release this cable.
The cable should slide out when the releases are pressed.
This cable can be difficult, as you need to simultaneously push the pins as you pull out the cable.
