Disklavier

I will photo for you this weekend and if I can find any markings, I will note them in the email.  Please see my other post.  I have also thought of finding a replacement but after about half an hour with some vendors catalogs, I concluded that the Yamaha replacement was the safest, fastest, and most cost effective solution for me.  
 
In the darkened room, you should be able to see the array of pixels that make up the two lines of text in the display even if they are turned off.  Did you see this?  You need to identify these first to see if you can see any characters faintly on them.  I know this is very difficult.  It's one of those things you cannot see unless you already know what you are looking for. If these characters are changing, then the display controller is working and it is a no contrast issue as described before.  In my case, a new display was an instant fix.
 
Regards,
 
Mike

I'm located in Bethlehem, PA (eastern PA).

I'm wondering if I could get enough information off the display and 
find a substitute. While I'm sure Yamaha would sell me one, I would 
hope to find one on the secondary market. Any chance of you taking a 
digital photo? 

Also, I can't make out any text with the lights low. The green 
backlight is bright, but nothing else. The player, otherwise, works 
great.

The display should, after about 10 - 15 seconds, display "Insert 
Disk" See if you can see the individual pixels of the display - if 
you look very carefully, you may be able to verify that there is a 
very very faint display of the "insert disk" text. If you can see 
this, and if it changes when you do insert the disk, there is a 
strong possibility that the display just needs to be replaced. If 
you do not see this, it does not mean the display is OK and the 
problem is elsewhere but that could be the case. The easiest way to 
determine the problem is to swap the display with a known good one or 
put your display into a known good controller. Where are you located?
