Cambridge Audio DAB receiver (Dane Hills LE3)

This model is a Cambridge Audio DAB 300 Digital Tuner but it has a fault. At one time it was part of my stereo system but then it developed this fault. The on/off switch doesn't work and, presumably as a consequence, the other function buttons don't do anything. I put it in my loft where it’s been sitting for several years waiting for me to do something about it. My guess is that for someone with good electronics knowledge it might be easy to repair so I've decided to give it away in the hope that it can find a home with someone who hopefully has the skills to fix it.
