This is my first post so hopefully the posting goes well. After seing a video on replacing the laser on a Beosound 9000 MK2 decided I could do that, purchased a laser and off we went. The process seemed to go well but on reassembly no laser function, unit is not dead display comes on,can switch between radio cd etc. I hope I have just blown a fuse but cannot find any information on the web to how I can access them. I removed all the screws on the backplate but the plate did not come away. Probably there's a fastener hidden so put everything back together. So my plea can a generous person(s) help and tell me how to access the fuses. Also it would be helpful if a fuse has gone, what is the replacement and where can I purchase them. If the fuseses are fine payback to me will probably be a hefty service bill for repair. Never too old to learn from your mistakes. Many thanks
