Hi Rodne, I'm Eduard from México. I'va learned a lot thanks to you.. so Thank you! You and other members here in the creek are my laser heroes. I have a ghosting or shadowing problem with my spirit deos 30w. I've read in a old post that you fix it this problem very easy.. you say it was a high a trickle voltage.. If you have some time.. could you please explain me how to fix it? Thanks in advance! Eduard.
