Disklavier

Bernard,
 
If you read down further in this post, you will see a copy of my original post re: the display.  Having a background in electronics, I was able to test and replace the display myself.  It is not that difficult for someone who is trained in this type of work.  I recommend you have a technician look at the unit if you are not familiar with this type of repair.  
 
My display was blank from the moment I purchased the piano from the previous owner so I do not know how long it was blank or if it went blank suddenly like yours or faded over time.  
 
Thankfully, parts seem to be available.  Nothing beats a working display - - accept, of course, a working display and a delicious piece of Swiss chocolate! 
 
Regards,
 
Mike

Hello Mike and Yadidisklavier,

I am from switzerland and have an MX100II. 
I disconnected the main plug of the piano while my holidays. When I
come back two weeks later I switched on the piano. Then I noticed that
there was no text on the display. Not nice.
The backlight was ok. I tried to check whether I can see any dots of
the character matrix by changing the angle of view but there was
absolutely nothing to see.

I'm interested how your (Yadidisklavier) display was repaired.

Bernhard

be lighted but no text visible unless you get the view angle just
right and then it is only a "hint" of text. You will need to have the
display replaced. I do not know your technical background but it is
not that difficult - two connectors if I remember correctly and a
bunch of screws to get at it. If you are not confident in this type
of work I would seek professional assistance. If you are in the
Chicago area, I could help you with this but otherwise you will need
some assistance locally. You can order the part as described in my
original post from Yamaha Disklavier technical support. Freddie at
Yamaha technical support can help you with this.
