Leo, at this point, it sounds like you better take MY suggestion, and contact Yamaha Europe RIGHT AWAY to get an official case number initiated. It's sounding more & more like a "hardware (batch?) defect" that could be corrected with a VH board replacement. Until you (and the rest of you guys with this problem) do this, nothing said here is going to fix it. Believe me. I've been there.

Chony, the problem in my situation was that (according to Steve at Yamaha USA), there were'nt enough (or any) other people complaining to get Yamaha Japan to take notice. In your case here, there may be enough of you out there to force the issue and get quicker action. Power in numbers they say. I say, at least make the effort and report a case with them on this issue. If you don't 'at least' do that, then (no offense), but you really have no grounds to complain.
