I have purchased several BM5000 and lately BM6500 which, of course, were advertised as "work perfectly". However when they arrived I set them up, and when trying to play a CD, the Beomaster powers up and immediately shuts down. I know this topic was covered in the "old forum" but didn't have an interest in it at that time. Is this problem in settings or does it need servicing? Unfortunately, there is no longer a B&O service shop where I live, so any repair would involve packing and shipping to a distant facility. Any help would be appreciated.
