I also have a very sour feeling toward Yamaha. I own two PSR2000s and a handmade Yamaha acoustic.
These two issues plus the fact that they often don't respond to emails makes me hope very much that in the next couple of years one of the other brands comes out with an alternative to the PSR2000's successor.
You know I have informed Yamaha twice, once by email and once over the phone, that two of the service centers they have listed in Illinois at their website don't service Yamaha keyboards. One has been out of business for two years and the other charges $80 an hour and will deduct the $25 per hour that they get from Yamaha. So you would have to pay $65 per hour for a warrantied repair. Fat chance! Yamaha has never removed these places from their website.
They just don't seem to care about their customers.
It's like Yamaha gave birth to my PSR2000 and I'm raising her. I feel like the marriage is over. Lack of service and corporate greed is like a deadbeat mom.
