Disklavier

With great anticipation, I have received my "new" MX100 II and it 
looks and plays beautifully!  Thanks to the info here for getting me 
started on converting the midi files of old reproducing piano rolls 
to Disklavier format.  The procedure is painless and the music is 
wonderful.

I did have a problem in that the contrast on the LCD display was so 
low that I could not see ANYTHING on the screen.  Upon really close 
inspection with the room lights very low and looking at just the 
right angle, I could just make out "Insert Disk."

Do any of you have a similar problem?

I have a technical background in electronics and armed with the 
technical service manual from Yamaha and my test equipment, I 
diagnosed the problem to the display itself.  This, I thought, was 
odd in that I have never run into a display which faded to nothing 
over time.

In checking with the Yamaha technical staff, I found out that this is 
not too uncommon for a display over 10 years old.  I ordered a new 
display module, installed the unit myself (about 1 hour of very 
careful work)and...problem solved!  Works like new!  Well, it is new, 
the display that is.

If you are suffering with a very light display, you may wish to 
consider having your display replaced.   The part is about $230 plus 
the installation time for your technician.

I have nothing but good things to say about Yamaha technical 
support.  Every contact with them has been first class.
