backlight

Hey, brothers, I've seen that "didobrain2000" has posted some photos 
with the change of the backlight of his unit. Do you know where I 
could purchase that "thing"? (the same one if possible, and if 
didobrain2000 confirms that it's working well yet ... Dido? ... ), the 
display of my K5m it's ok, but the backlight virtually doesn't exist, 
it's just a thin almost dead green line ... 

Best regards for all of you, people, and thanx in advance.
