Yup! Finally happened to me. I was in the middle of snapping wedding formals at the altar, and my d200 just decided to die.....and it was before her time! For no reason she just went down....no power! Shes only 6 months old too so she's still under warranty. Don't worry it wasn't the battery, lens, or cf card malfunction as I switched 'em all out a couple times each....it's internal failure. THANK GOD I ALWAYS CARRY A BACKUP BODY! Any ideas on what happened? I got the camera from B&H, should I contact them or Nikon?
