Yes it did.

I think my problem might have been a result of my grandkids playing style (pounding on the keys).... But it was fixed.
One other thing I thought of...there is an opening into the main body of the keyboard...right by the middle section. I wish I had tipped the keyboard away from that direction...as I dropped one screw, and it went right in the hole. So, I got to remove all the screws also , Stephen!
