I need help with my camera, please help??
OK, so I have a Nikon Coolpix 4600 and the first time that I have that worked very well Suden now only flash indicator blinks and no flash. The manual says the flash is charging when the indicator is blinking, but the day today and the flash does not work. I changed the battery setings changed the camera to see if I can get the flash to work, but nothing so far. However, take pictures, but without flash. Can someone please help? Maybe there is something else I can do to get the flash to work?
The flash will not operate in several modes of the camera. It will operating in the landscape, sports, sunset, night landscape, museum, fireworks or modes dusk / dawn. If you have tried the basic AUTO mode (the camera green) and the flash does not work, I think it is time to consider a repair. There may be some confusion about the light is. You did not mention the color. There are small labels for each light, but can be difficult to see. The flash light is the top light will blink red while the flash is charging. The Attention light is backlight and is green and blinks when the camera can not autofocus. When you turn on the camera, red light flashes while everything starts and then turns off.
