disklavier MX100 II service manual, upgrade
2014-04-23 by <mbutterfly548@...>
HI,
My Mx100II have problem in these days. It plays couple note then stops. On LCD, it shows "piano power off (PWM over)". As for other function on the computer, they work well, like metronome..." No sticky key, no pedal problem. I think it some power supply problem.
So, Where can I get yamaha disklavier Mx100II service manual? In previous, someone repaired that, but the description is short, see here, http://www.pianoworld.com/forum/ubbthrea...X100B%20wi.html
I can not figure it out Where is the 20V-regulater (IC2 MJN78M20FA) located?
Is that possible to get other additional voice through tone generator when I play the piano?
Many thanks.
