Here are all the easily removable/ replaceable circuit boards from a Kawai DX1700 organ I parted out. The organ was not working at the time but I think the problem was with the amplifier because when powered on it would blow a fuse on the amplifier section.
The boards all appear to be in great shape with no visible problems. Might be a good way to try to fix your non working DX 1700 on your own before calling in an expensive repair person. Or just keep them around for spares as the DX1700 was a very expensive organ when new.
Send your zip code for ship cost- should be between $9.95 and $16.95 if you are in the continental USA (Nov. 2012).
