Wow...........I've sold dozens of PSR700's and 900's and I've only been aware of 1 major problem and this was probably due to the keyboard taking a large bang by Fed Ex in shipping to Don Mason. Don called me immediately and told me there was a hairline crack in the back of the keyboard. He was offered to return it for replacement or if he would like to keep it at a better price if he could live with the slight crack. After a few days Don decided to keep it because it seemed to be working fine. Now, this problem of the pitch changing started and Yamaha suspects that a circuit board might be cracked because of the blow it must have taken which cracked the outside casing. So, Don has been shipped a new one from me two days ago and he will return the bad one which I will return to Yamaha for replacement.
The only other minor problems has been one keyboard had a loose screw in one of the speaker housings which the customer took care of himself by removing the wooden bottom cover and finding the loose screw and the other was a loose connecting cable from the key bed to the main board which arrived that way to my customer, he returned it, I opened it up and found the connector cable partially out of it's socket, plugged it all the way back in and it's been sold and is just fine.
That's it from here. My cusotmers are loving their 900's.
I really don't think there is an issue with US shippments. I think it's just been a case of bad luck for a few.
