Hi, after an exhausting search for a keyboard that would suit my needs, I finally bought a Korg N1. The LCD started black, and now is not working at all. The keyboard plays, so does this mean it's the adapter or the LCD itself. I'm very upset. I looked at the Alesis QS8 and Kurzweil PC88, and regardless of everybody's opinions I really liked Korg's sounds and action. Now I'm beginning to have buyers remorse. Please tell me it's just a bad adapter. :-(
