Kawai Synthesizers

Hi David,

Does it look like the display area has been hit or damaged? LCD 
displays have 2 rubber strips that run between the driver board and the 
glass. These strips make the connections from the LCD to the board. If 
the display takes a hard enough hit the strips can get misplaced 
causing bad connections. Usually not this bad though. Another problem 
could be the connector is plugged in wrong ie. a pin off or backwards. 
Then there's always the possibility that a component has failed. The 
display needs 8 bits and several enable lines plus power to operate. 

Have you opened the synth up and checked for the obvious yet? Let me 
know what you find I can compare it to my K4r which I have here before 
me. I just picked up 2 K4 Sound Source cards that I'm checking out. The 
D-50 and M1 Impressions cards. They sound really good so far. 

HTH, Fran
