Hi, I have a Nikon d300, when turned off the cf light blinks continuously and quickly drains the battery. I have tried a new cf card but the same thing happens. Is there a fix for this?
Hi there Martin and welcomeCan you remove the batteryThen hold the Shutter button down for 60 seconds then release.Put the battery back in, turn on the camera, turn it off and tell me if you still get the issue please.
