I have two 473nm lasers. A CNI and the even cheaper "I have no idea who built it" laser. Idea being to combine the beams to match my powerful red and green lasers.
ANYWAY, the cheap Chinese laser works fine. The CNI is dead. I do not have a warranty on this laser and want to see if there are any outfits which will take in a complicated laser like the CNI 473nm and repair it.
As always, thanks for your help people of the Lexicon ;-)
