I have a D80 when I turn it on it gives Err on the display.
I've dispressed the shutter but the Err just comes back,
I can view pictures that are n the card.
Hi,Does the camera attempt to focus when you press the shutter button half way?Do you have another lens to try:
It doesn't try to focus
Do you have another lens to try:Will the camera shutter fire in manual mode?
The shutter sounds like it is firing but there is no pic. and the Err message comes back
I reset the camera and that didn't help.
Does it give you a numbered black frame, like a photo was shot, only totally black?
totaly black. I can view pic. taken before that are on the card
Remove the lens set the camera in manual press the shutter button and observe the mirror. Does it flip up? If so then the problem is with the image sensor or mechanical shutter. If the mirror does not move then it is a sub-mirror failure which is a little less expensive to have repaired
Please keep in mind that my diagnosis & solutions provided are directly dependent on the accuracy of your description of the problem. As with any "do it yourself" fixes, success is a "team effort", since I can't see or touch the camera, and relies on the customer's manual dexterity and ability to follow the instructions well.
