Hi, whats up, its Nicolas again, im going mad, its been like 5 days 
since i last played the piano...
I´ve checked the output of the transformer and its working. Ive also 
noticed that the two upper fuses are shorted to ground. Is this 
normal ? When i check the cables that supply the other boards there 
are three that are ground, the brown, the white and the black one. 
Is this ok ? Also, none of the regulators have any voltage between 
the (+)&(-) pins.

Also, when i disconnect the supply to the other boards after the 
regulators the two upper fuses arent shorted anymore. 
Anyone got a schematic ?
has anyone got an idea of what to do next?
Im really missing my keyboard, and im to poor to pay the 15 u$ plus 
shipments for a manual offered by kawai us, which  i suspect doesnt 
even have the schematics.

Thanx again for the support 
nicolas
