I recently went to Europe and took my Sony N707 with me. After plugging the charging stand into my voltage converter I got the error 'Hi DC In' error. Since then, the charging stand (BCA-WM25) doesn't work. AA batteries work in the recorder, but it's aggravating that I can't use the stand. Can I get a replacement? Or will this charger work again? Did I just blow it up or what?
