From the fact that we don't seem to have many posts at roland-arranger.com about similar problems, Adi (and we have quite a few E60 members, don't we?), I don't believe this is something wrong with this particular model...

The E60 uses a power adaptor. Have you replaced yours? Have you checked that it is the correct voltage for your country (voltage AND cycle rate)? And have you tried plugging the power adaptor into a UPS (for your computer, maybe?) and seeing if the problem occurs..?

Power adaptors have what I consider pretty flimsy cables, easily crimped or damaged. Double check yours for kinks.

But buy another one, anyway. Even if it ISN'T the problem, you will be better off with a spare...
