After not using the Boston Horison solo for a few weeks with it unplugged I plugged it back in. It started a quick scan for dab stations. After scanning aprox 6 stations it has frozen on station 12D 229.072. The only way I can get out of this state is by unplugging it and plugging back in. It then does the same again and freezes on station 12d 229.072. I have left it switched off again for 48 hrs and tried again with same result. Do you have a solution for this ?

FM radio settings

displayed during the autotune.
When the autotune has finished, your Elan E3 will tune to the last station that you were listening to. If the
last station you were listening to is no longer available, your Elan E3 will tune into the first station in the
alphabetical list.
Manual tuning

1. Press the Menu button.
2. Turn and press the Select dial to choose ‘Manual tune’.

I don't know if you will see this or not, your post was 2 years ago. I have the same problem. My volume is stuck at 24. I have tried soft-reset........among other things. One thread says to turn volume down to 00 then press for 10 seconds. I have no control over the volume, so, yeah, thanks for that fix. I found that I could get the volume down by unplugging it,plugging it back in and sometimes the volume would pop up and I could turn it down one notch. I did it till I got to 00.............thought AHA! My problem is solved! No such luck. When I press the volume at 00 and try to hold it for 10 seconds, after 3-5 seconds it just pops back to the station frequency. I also thought that if I could get into the guts and spray the volume control with tuner-cleaner, it might help. No go.......after taking off the cover, I found a bunch of REALLY delicate looking electrical tapes and wires..........I was scared I would destroy something in an attempt to reach the volume control. I hate to trash this radio, the sound is awesome...............great design on the speaker, NASTY design on the controls. I'd be VERY interested to know if anyone, anywhere, has found a fix for this. I think maybe my next step will be hitting it with a hammer.

I have had this happen several times now. Unplug the Bose power plug for a few minutes, then plug the power back in and turn the Bose back on. It has reset the Bose unit everytime and the audio is back.

To perform a "soft reset"(all settings are erased)
Unplug radio
Hold alarm 1 button and plug in radio
Keep holding alarm 1 button until 3 numbers appear.
Release alarm 1 button and unplug radio.
Plug radio in and all will operate normally

Unplug Bose Solo power for a few minutes then plug back in, this has reset mine several times.

did you find a solution with that problem, other than throwing it in the garbage that is?

No solution, but I have the same item showing the same problem

Hello
I experienced a similar problem some time ago. I thought I was responsible for the problem because I run the radio of a dual voltage shaver socket and accidentally switched the socket output to 110v. From that point on the radio did excactly what you described. I perservered in trying to find out why but to no avail so I abandoned it. Some months later out of curiosity I plugged it, switched it on and it worked perfectly.
Try leaving it unplugged for a few days (which by this time will have already passed). It may just recover like mine did.

You have leaky filter capacitors in this radio, this is a common fault and these are soldered into a rinted circuit board. Good luck
