I recently purchased a non-working SoundTouch portable. The seller thought it was just the battery, but that does not seem to be the case.
I have tried hard resets but am not having any luck.
Bose Support has stated they can fix it for me for $99 if I send it to them. I’d like to see if there are things I can do before sending.
Hey Joseph,
Seems that I have a very similar problem as yours.
Unit does not show any signs of life.
I replaced 2 caps on power pcb that were slightly expanded. Still no life.
When I measure volts on batery terminals on a speaker side, I get 18V. However when the battery is connected, the most I get is 8V.
11V battery can’t get charged with 8V. And batt is dead completely. Nothing on any terminal.
Have you figured it out if unit can be operated on AC power without a battery?
Thx

I have a similar problem. New battery - 20 V on the power supply - factory reset and updates done - battery won't charge. I need some advice on whether this is a hardware or software issue?
Same seem to have happened to my unit after I was forced to upgrade to the latest firmware.

If the battery is not charging (and app. stops working because empty battery) then a condensor of 10uf/35V is defective (to high ESR). Naer the coil.

Dear Edzard,
can you please describe a bit more detailed what capacitor you mean?
I do not understand "Near the coil", what coil you mean.
Yes - a pictures would be very helpful.
It happens to me that the system turns on but is disconnected from the battery and the speakers do not sound. Is it the battery that is defective or the motherboard?

Is the Soundtouch playing music and it doesn't sound or is there no music?
If the sound is poor, it may be that the speakers aren't properly seated in the enclosure. The back of the speakers must be airtight.

I’m looking for a way to eliminate the battery, as I can do without the portability.
When I take out the battery, the unit will still not boot.
Does anyone have a schematic of the unit, so I can bypass the battery and just use it on the dongle AC power?

I ended up sending it to Bose to have them fix it.
I did check continuity and some other things, it seems that my issue was a blown board.

@Joseph, did you ever find a way to use the speaker? It is really annoying to me that it won't work without a battery, I have replaced mine twice even though I never needed portability. I really don't want to buy another battery.
