Disklavier

THANK YOU !!!

For those suggestions, It worked ! The unit is now operating flawlessly ! Such a trouble Is it likely  to come back ? Since Im thinking may of selling it if I go for the DKC850. 

And by the way any idea if this unit (DKC500R) would work for replacement of with other disklavier models if I sell it. Also any idea of a fair price for such item...?

THanks again!
