Disklavier

DO NOT REMOVE ANY TWIST FASTENERS !!!
 
THe entire display comes as a unit; display itself, and PC Board permanently attached!
The display will come out in one piece.

lol - you're last sentence...thats my dillemma. Even though the tech 
diagnosed the display as being bad, I could very well get a $250 
display and find out there are other issues to diagnose. I think the 
fact that there is a component (looks like a very small transistor or 
diode)with a broken lead, was how he made the diagnosis. Sounds more 
like an assumption to me. 

The board looks easy to take out. The hardest part being the metal 
twist fasteners holding it in place. 

I'll just let the tech do it and hope this doesn't get any more 
expensive.

Thanks,

Geoff

mounted like the old one and the cables plugged into the same 
connectors being careful to install the connectors in the correct 
orientation. This assumes that the display was definitely at fault 
and all that is required is a new one.
