Some months ago I bought a Sony Ericsson MW600 bluetooth receiver to use when working out. Unfortunately after a month it started malfunctioning. One day during a workout while playing music it made a beeping sound every few seconds. I turned it off and tried to turn it back on but it refused to do so. I left it to rest a few hours and tried again, this time it worked. However, from that moment on I couldn’t get the MW600 to turn on reliably anymore. This weekend I figured I should try and peek inside, see what’s wrong. There’s a video on YouTube showing how to open it up but it’s not entirely clear at some point so I made a picture guide how to open it up properly. If you have a white version as is shown in the video I think the packaging is a little different so you might have to figure out a thing or two on your own. If you have the black version, this guide should be sufficient to completely disassemble it.

So, how do you start?

Make sure you have small cross and flathead screwdriver and a small box to put in the tiny parts of the MW600 so you don’t lose them.

I will try to give a little explanation next to each picture (click to enlarge) so you can comfortably take the device apart.

 Let’s get started! DISCLAIMER: I’m not responsible in any way if you break or damage your MW600 in the disassembly process!

.

First of all you need to remove the little plastic cover below the microUSB port.

It covers up the first screw that holds together the port cover and the main body.

Remove the screw.

.

.

Remove the plastic pushbutton to reveal the actual pushbutton.

Take care when handling the parts. I managed to break off the little pushbutton to power on/off the MW600 and it’s really easy to lose it!

It’s very fragile so make sure you handle it with care.

Next is removing the clip. Slide your fingernail between the two parts highlighted in the image on the left. While you gently add space between them, use your other hand to push the clip upwards until it jumps free.

This will reveal the second and last screw you need to remove.

.

You can remove the other plastic part from the main body. Once that’s out of the way, we’re almost done removing parts to remove the PCB from its plastic cover.

.

.

Next up, on the side of the device, there are Previous Start/Pause and Next buttons. In fact, that’s just one strip of plastic. Use a fingernail to remove this strip. Under it there’s a small metal thingy, make sure to remove it as well.

.

.

Lastly, there’s a plastic part that surrounds the gap, again, use your fingernail to remove it from the main body.

.

.

.

.

Continuing, now you’re free to remove the plastic hull, make sure to remove the call button in the process as it isn’t attached to anything else and will fall off.

.

.

.

It gets a little trickier, try not to break the cover for the screen. You can detach it from the main body at the highlighted area. If there’s some glue holding bits and pieces together, don’t worry, you can pull it off without breaking stuff!

.

.

Once that’s done, you can turn over the device and remove the battery. It most likely will be “stuck”, just use a little force (or use a screwdriver) to remove it.

.

.

.

.

To remove the PCB from its cradle, you’ll have to detach a few things. First of all the 2 flaps on the left. Next are the “sides” where the touch-sensitive volume slider is. Lastly the other side where the prev/play/next buttons were. Both sides have a bit of PCB connected with ribbon cable so you can easily bend them without worrying you’ll break the entire PCB.

.

.

.

After some messing around to remove the PCB (do take care as even if it can bend a little, the 3,5mm jack is lodged pretty hard into the plastic, make sure it’s loose before trying to “pull” on the PCB!

As you can see in the last image, do not use the MW600 for working out if you sweat! I used it for running and as you can see my sweat completely ruined parts of the contacts.

Whatever reason you had to take apart the MW600, I hope you found this guide useful, if you have any questions don’t hesitate to leave a comment and I’ll get back to you as soon as possible.
