That is totally unacceptable.
Yamaha is supposed to be better than this.
Most of us know that most brands have two ( or more ) levels of products that they sell to consumers , i.e.: Pioneer , they sell there standard stuff and they have there "Elite" line.
For Yamaha audio , it too has two levels , the stuff you can buy at Best Buy and other like stores , and stuff that you can only get at specialty stores. ( i.e.: there new HT amp :

In any event , it is clear that Yamaha has two levels of products , look at there low end KB the YP-T400 almost the same as the PSR-E403 ( slight difference ) , but you won`t find the E403 anywhere but a music store ( in most cases ).
Yamaha , it really doesn`t matter what or where you sell your products , what matters is quality.
I realize they {Yamaha} would people rather buy a Tyros than an S900 , but that is not the point.
If your going to offer a product on the open market , it damn well better work and be in one piece.
You {Yamaha} stand to lose a large customer base if you don`t shape up.
So fly right and get your act together.
