Question about Nikon D40x Digital Camera

1 Answer

My D40x has developed some type of contact issue. Frequently when I try to shoot, the red focus indicator is displayed in the screen but there's no sound or focusing to go with it. If I remove the battery and reinstall, many times it works OK. It's like it's getting partial power for some functions but not all. For example, the menu will display. I've tried my spare battery too and had the same symptoms. Seems like a bad contact, and I'm wondering if there's a simple cure or if it will take a tech and $$ to get it fixed.

Have you tried cleaning the contacts first with a pencil eraser and then with a cotton swab lightly dampened with rubbing alcohol? It also wouldn't hurt to clean the contacts on the camera body and lens where they meet with the cotton swab.

Wife dropped nikon d40x on concrete...will only shoot on manual. Lens will not autofocus.


Lens motor(inside the lens) could be damaged already. The D40x focusing system is dependent on the lens, just like any other Nikon Dx camera except for the ones that has built-in motor to its body, e.g. D90, D7000. Try a different lens, most likely it should work

I have a nikon d90,when i pressed shutter button ,it is giving err message then i press second time it is not giving err message but not taking the photo.


This is an indication that the camera is not "talking" to the lens correctly. When you press the shutter button, the camera tries to focus, set light levels, and then shoot the picture. If it can't focus or set F-stop and shutter speed, then it can't shoot the picture and gives you the error indication. SO
1. You need to make sure the lens is an automatic lens capable of working with the D90. 2. You can take the lens off and back onto the camera a few times in case its a dirty contact issue or just didn't seat correctly. 3. Set the D90 to manual and make sure you move the AF selector on the front to M. Then you would manually adjust all the settings. That should take the auto-coupling out of the picture (pun intended)
4. If it still shows error when in total manual mode, there may be something wrong in the camera itself. Before giving up, do a total system reset on the D90 (I assume you have the manual).

My FM10 focus screen does not focus, but split image works


I have seen bent mirrors and mis-aligned focus screens do this. It is possible for the film plane to be in focus while the viewfinder is out. you can test this with newspaper and a tape measure. buy a cheap roll of neg film and set up your camera on a tripod at a fixed distance, say 6ft. from the paper. Ideally I'd attach the paper to a light stand or the back of a chair. so that the paper is at 6ft, the back wall is at maybe 10ft. and there's something in the foreground in case its front focusing. then set the lens at what the scale says is 6ft regardless of what the viewfinder looks like. Shoot one frame with an aperture of f/2.8 on your 50mm. Shoot a second frame at f/16. rewind the film & develop it at a drug store or 1hr lab. if both images are sharp, the problem is in the mirror/ prism. if the 2.8 is OOF it's the mounting ring. I want you to shoot the F/16 to prove that the stop down lever is functioning.

White Pictures


if the camera is on a very reflective surface such as sasnd or snow, sometimes the light meter can be fooled and so you have to try to find a snow mode or manually increace the apeture or shutterspeed or lower the ISO you might also check to see if the camera is set on a very high ISO, or very low apeture or shutter speed, another possibility is that the exposure level is set very high or is locked so the camera will over expose, also if you focus the camera on a dark object, then the rest of the picture will be over exposed, so try to focus on a object that is about halfway between black and white.

Nikon D40x AF-S Nikkor 18-55 mm 1:3.5-5.6 GII ED Lense Trouble


I've found the same thing with my D40x and the 18-55mm AF-S lens. I took a really close look at it and found that the mount on the lens is badly worn on all three of the bayonet tangs and one is cracked at the base. What happens in my case is that the lens has movement when mounted on the camera - just enough to stop the contacts from mating properly. Hence, no photos. Am taking it to Nikon to get it fixed. I suggest if this is your problem, that you take it to the repair man.

Nikon d40x...many thanks..micky


Unfortunately, there is no live view on the D40X when framing shots. You can only use the screen to review your shots and to make settings.

Nikon D40X stopped auto-focusing yesterday


I had the same problem. My issue was with all my lenses. I solved it by going to the menu and selecting the custom setting menu (pencil icon). Then from the right menu select the AE-L/AF-L and press OK. Then make sure it is set on AE/AF Lock. Presto...all my lenses worked on auto-focus.

Flashing red square area in viewfinder.


No, I don't think so, there could be differences between the Auto and the P setting. But the red flashing is where your camera is currently focusing on. It's possible that the black was indicating the focus box, but it was not latched on to something with complete focus, which then is indicated by the red flashing. Check this link to read up further on this. I may not have pinpointed it exactly, because I have a D70s, but that's what I found so far. You'll maybe have to reset everything and see if it's still there, otherwise, it's a setting. =)

Sounds like you need to get your camera fixed by Nikon.

However, you say the auto focus stopped working, you didn't switch to a lens that uses a mechanical focus linkage do you? The D40 only supports lenses with AF-S or AF-I type autofocus drives. AF-D and AF-G types without AF-S or AF-I don't autofocus.

Also, check that the A/M switch on the lens is in the correct position.

Manual focusing is quite difficult to do accurately with an AF camera. The screen inside the camera is not optimized for this. If you are sure you are focusing accurately but the pictures you take are still out of focus, the mirror may need adjusting. I can provide further info on this if you require, but if you're within warranty, i'd recommend that route first.
