Nikon Flash Fix

I had the same error message, the camera is less then a year old, however, I was taking up to 800 pictires every weekend of my kids soccer games, then a 6 month trip to the Pursian Gulf, that is when it started, I got back home, took it right in, and one year later after a few visits and calls trying to find out where my camera was, I finally got an answer back, they said I needed a new shutter which will cost $300, They said I should just by a new body for $400. What Nikon does is set that error message to pop up at about 35000 shutter releases, and you can't do a thing about it, once they hooked my camera up to thier system the said I had over 36000 shutter releases, where the average person takes 10000 a year and they want you to replace the body every 3 years....so before buying any camera, always check out how many shutter releases you can get when you buy a camera

Nikon D40 Flash Fix

This happened to me once on a D70... When mounting the lens, make sure it clicks in all the way when turning counterclockwise. Also it may be worthy to note that both the lens AND the camera must be set to autofocus mode ("A" switch set on both lens and cam).

I was taking pictures, then when I pressed the shutter release button, it took a long time. Then the error message came up. I tried pressing the shutter release button again, nothing happens. Still the error message. Please help me

The manual (pg 112) simply, and unfortunately, states this message "Press shutter release button again. If error persists, consult with Nikon-authorized service representative".

Some questions that might help: have you had the camera in some extreme conditions, damp, sand, etc. Clean the shutter button really well. Maybe use a small air blower and clean in the shutter release creases.

In the end, if the error continues, it will need to be serviced.

If you remove the card from the camera, there is a little switch on the SD Card. There is typically a label that shows which direction is locked. If not, switch it to the opposite side. This should solve the problem. Otherwise, there could be a problem with your card. I hope this solves the problem.

the little trap door on the bottom houses both the memory card and the battery. you have to push the battery slightly to release it. i fond the easiest way at that point is to tip the camera and the battery usually slides right out.

This battery cannot be used Choose battery designated for use in this camera

I ran into this exact issue (64GB Sandisk SD not working with an old Nikon D40). The problem is that the camera requires FAT32 formatting, which is not supported on partitions greater than 32GB (i.e the 64GB stick). A format from the camera attempts to repartition all device space (64GB) which is incompatible.

I solved this by connecting the SD to my laptop, opening the windows disk management utility (diskmgmt.MSC), deleting all partitions on the SD (right-click, delete partition on all allocated space), the right clicking the unallocated space, add simple partition, then allocating only 32GB and using FAT32 as the format (any more and windows will only provide exFAT as an option, also not compatible with Nikon D40). Plugging that into the camera and NOT reformatting from there worked.
