Re: [disklavier] Re: Mark IV service manual? /keyboard not working

2012-09-26 by Roberto Fasciani

Hello everybody,

I have the very same problem since 2 months.
Keyboard doesn't move at all. Pedals yes, quiet mode working. During keys test no one key moves.
Internal PianoSoft library doesn't play as well.

I already unplugged power cable for 3 weeks while I was on holyday and I tried on my return. Nothingh happens.
Cables already checked (thanks for suggestion atomik).

I have tried to inspect the circuit board opening the wood cover over the keys and I found everything connected and a series of red leds are on (so power supply is connected).
Maybe bty8743 may check red leds this way to ensure power supply connection.

Any suggestion before I buy a new keys control board?
Anyone knows the price?

My DKV is a DC3MIVPro aged 2007.

Thanks in advance for your help

Roberto

Does the piano play back from the internal PianoSoft libra ry?


If not, check the PD/KD cables going from the I/OCentre (big metal box with lots of ventilation holes) to the PK control unit (small box under the keybed at the treble end). You're looking for the green and the blue RCA phono jacks. If the piano is old, there has been an updated version of the cables. If the keys don't even work from the internal files, you may also have a problem with the PK control board.
