[sdiy] DS Poly Evolver Keyboard LCD Backlit broken

[Sebastian Schünemann]

Hi @ll,

I have a Poly Evolver Keyboard with broken LCD backlit,... everything 
working,.. only backlit without function.
I did a search on the www but couldn´t find any schematics.
Is there anyone out there who had similar problems or is willing to 
share schematics?

My main question is:
Could anything else be responsable for this fail or do I have to switch 
to a new display and everything is fine?

Many thanks,

Sebastian
