Hey all. Need a little help. I have a gen 2 pro monitor and all of a sudden the image will go fuzzy and then will come back sharp randomly and again will go fuzzy. It's not a battery issue... I remember on the old cp3a it used to mean that a focus tube was going. As far as I know, can't see any focus adjustment inside the gen 2 monitor. I know my gen 1 monitor has a focus adjustment, but have looked everywhere for one in the gen 2. Any ideas on what the problem is? Thanks in advance.
