Non Working Kawai K5 Part II
2004-07-20 by tuff_gnarl_69
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
