Hey.., I wouldn't just praise Yamaha's support on this site. I give Yamaha an A+++ on their support. Back when I was having that issue with the NP-30.., I had contacted Yamaha several times (I think my issue was the first report to come in). I didn't hear from Yamaha on it and on another forum I had mentioned I kinda felt shafted as it seemed Yamaha was ignoring the problem.., well that next day Steve Deming gave me a call at home Problem was replicated.., parts shipped, unit fixed., and all was well..
