Hey guys.

My MX1500 has lost its sound and colors, I've just read that the colors may be do to a failure of the battery. Thanks for that. But what  the sound? Is that do to the battery failing as well or is it just broken? And can I fix it my self?

I'm new to the world of B&O and there any guidance is appreciated

Thanks in advance

If you know how to handle a soldering iron you can replace the back-up battery. I would replace it and see of the other problems also are solved. The battery is not the most expensive part.
