I've personally never experienced a keyboard failure. However, of the few that I know that did send their arrangers back to the factory, the wait time varied from 2 to 6 weeks before it came back to them. That's why I emphasize backups so much - including keyboards.

Long time ago, when i played in a band.. And everything was hardware and not software, our local music shop offered replacements in less then an hour when something failed on stage...
But nowerdays with i ternet buying, its a different ballgame...
I am glad, i only play at home for my own leisure, but still its frustrating if things break down, and all the backups in the world could not solve this problem.. Its the controll print to the buttons and interface that keeps bugging out..... Its been replaced twice... But then its probably another components failure breaking the controll print like a short circuiting power supply or other part..
