K5synth

Hi, my name is Nicolas, i´m from Argentina and
i own a Kawai K5 synthesizer. The unit has been
working perfectly for the last 15 years, but today i
couldn´t turn it on. I opened the unit and checked all
the fuses and they were fine. Then i checked the
transformer and it was recieving current but when i
checked the regulators on the front panel none of them
had V on their outputs. I don`t want to mess around
with it unless im sure what im doing.
I´d be grateful if someone could provide me the
schematics, so i could repair the unit, its far too
expensive for me to send it back for tech support. Any help would be
welcome.
Thanx a lot.
Nicolas
