I received my V3i back from the factory they changed the circuit board and replaced my Eclipse Shooter "DD" (4x6) the problem I had was I only had a white screen when I would power the unit up. now works fine, I took my v3i out yesterday for a couple of hrs. I was in the coin mode and coin and jewelry mode Now I can hear (RRRRRRRR) if anybody remembers how the old Rotary phones sounded like when you dialed this is what I hear in my wireless headphones now when I swing? Any suggestions
