Just been doing firmware updates on my 3200s - I have two pairs. All went well except for one, which refused to complete the update.

Investigation showed that in the power/re-powering sequence that is required the speaker was not actually re-powering - it was dead!

The little green indicator on the rear flashes momentarily when the power lead is put back in, but then extinguishes immediately. Of course the speaker no longer functions. I checked the fuse but not blown. The mains pins all look good and well aligned.

I removed the back or a quick peek but decided to put it back right away - looked a bit tricky, but must be something to do with the power supply.

Any ideas please?

Thanks regards
Huw
