Any Toshiba driven 240x64 will do as long as it has a CCFL backlight!!

They are getting a bit thin on the ground now, but if you can source 5V to drive an LED model..
You may need to swap out the side connector!!
 
Does the unit still display and just the backlight is out? The way you can tell is plug the display back in, and shine a light from the side with a flashlight. If you see characters, it could be the CFL.

Hi Overclocked
The unit displys the problema is only with the display has alot of white áreas and lines.
The back lights work
I send some photos
 
After studying your schematic it seems like the controller is not on the graphic display..

The chip labelled "LCD BLOCK" can you tell me what written on it!!

As this chip has the RD,WR, RST and CD + the data bus... It may be possible to hook a normal display to these pins.

This depends on the controller chip!!

Do you think with this one it will work?

How do I know how to make the proper connections?

If you are not comfortable doing it, I suggest don't.... If you trawl ebay you may get lucky..

Ian Rogers,

Could you help me to find the display for this keyboard? I tried with topwaydisplays but it is outdated without controller.

Thanks!!

Same here! If it were mine I would try connecting the display to the other side of the LCD block. Risky if you don't know what you are doing..

If you contact New Haven Display's they may help you!
