$74 dollars later....the LCD problem is diagnosed.  It seems that 
some components came loose off the LCD board.  Because the board is 
printed circuitry, there isn't a chance of reattaching and the 
technician tried to call Yamaha today for a replacement.  Yamaha 
wasn't open today..."carpet holiday"...what the heck is that? 

MIKE - it looks fairly simple plug-in procedure.  Do you recommend me 
going the distance and having the tech install the new board?  I 
really hate paying someone for something I enjoy doing....keeping in 
mind I have already paid him to diagnose.

will 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.
