This teardown is not a repair guide. To repair your Sony SRS-X3, use our service manual.

There are 6 screws under the rubber feet on the bottom. Removing them allows the bottom plate to be removed, and then from there, the front panel, front cover, and battery compartment.

Hie my speaker doesn't recharge anymore the port were you connect to charge seems to have broken. I was wondering if youll be kind enough to tell me the name of that particular part and how to swap it. Thank you

  • More images of the main board assembly.

  • The pinouts of the main flex are actually stated on the board which is a huge plus.

  • A CSR Bluetooth SoC and MXIC flash are provided.

  • The battery pack is on a connector and can be removed before all of this is taken out.

  • Battery is a 2 cell 18650 pack with protection built in; 7.4V

  • Two 7W speakers with strong magnets are included in this speaker; it is marketed with a 20W power output. Excursion is about 7-10mm at its peak.

  • Two passive radiators are present inside the device. They're fairly heavy but rubberized, and they resonate and are tuned for low frequency reproduction. These move a LOT when it's playing. 7-10mm per side.

This is great, thank you Larry. I'd wondered about the possibility of upgrading the battery to one that lasts longer between charges but I had no idea how to open the case. It didn't occur to me that the screws would be under the rubber feet!

Dear Larry, can you give me capture specific card power close to battery. Because i got resistor blown in that card, and i don't know specific value of this resistor. Many Thanks in advance

One speaker started to give a lot of distortion making it unusable. Repositioned speaker in the heavy (magnet) housing and it's all good again.

Thank you for the opening tips and pics!

Larry,

My mini connector for dc into the board has broken. Replace connector or the whole Board? Where can I get a Power Board?

Where could I find the replacement speaker? My right speaker is buzzing a little on certain songs. Thanks!

I’m not sure if theyd be the same diameter but in general I would suggest searching ebay for “15W full range” and looking to find one with the same measurements that you might be able to fit in there. Might want to change em as a set.

Main thing to watch out for is that you seal the speakers up against the case well. Perhaps some glue of some sorts may be of help.

someone above noticed that there was some buzzing caused by a mispositioned magnet. May be worth checking out.

This may be what you’re looking for but do confirm the size.

Hi, I hope you’re still monitoring this page? I’m trying to locate a replacement power circuit board that has the USB charging port on it. It’s very flimsy and the port has disintegrated on my unit. I have tried replacing just the port but my soldering skills at this tiny level are not good enough, so I want to replace the whole board with a new one. This is the number on it:

SONY 40BKB537U-CNF2G

Does anyone know where I can get one of these? I’m in the UK, but happy to get sent in from anywhere overseas.

Thanks,

Clive

Hi Larry,

Seconding what Clive said, I need to replace the power circuit board with the USB charging port. Do you have where I can find that part? SONY 40BKB537U-CNF2G .

Thanks!
