[sdiy] DS Poly Evolver Keyboard LCD Backlit broken

[Luís Marka]

Hi Sebastian,
I was able to bring back to life the backlight on an Akai S3000XL 
sampler by replacing the fluorescent thing with a set of SMD LEDs, 
assembled in a strip of protoboard. To spread the light evenly I used 
parts of an old LCD display acrylic/translucent sheet that was removed 
from a dead instrument. As the original piece of acrylic was much 
larger, I had to cut/polish it. Only wiring I could use for the LEDs was 
that thin insulated wire stolen from an 80-way hard drive cable.
Now, I am not sure there will be room for that in your synth display, 
the one in the Akai had just the right space for this.
