Ive had this problem for the last 24 hours. Found a soloution but you will lose your entire library!
1. Un-plug the mains lead.
2. Re connect and at the same time press the on/off button on front until orange light stops flashing.
3. Press the up down left and right buttons on front straight away.
4. Red light should then come on. Turn machine on via remote control.
Sorry if you lost your library (like me!) but cheaper then buying a new unit!
