Re: nikon d40 shutter not open
What are the exact symptoms? What have you tried already? It's impossible to tell from your description whether the shutter is the problem. If it is the case, then you'll need to get it waranteed.
I assume the lens cap is off, you have the lens attached correctly, the AF is working ok (by default the shutter won't fire if correct focus hasn't been obtained.) and you have a memory card inserted in the camera?

when the still camera works the shutter of the aperture and iris is opening for a limited time, if it opens without limit the excess light will enter in and the result will be blurry picture, if the shutter is not opening the picture will be dark. in movie mode the shutter will be always in opened state, so I think there may be fault in shutter.
in some cases a slight jerk giving to cam when you depressing the snap button will reset the shutter and will work normally.
did you charge your battery full ? if the battery is not charged enough, it will not drive the shutter opener motor perfectly, and if any type of dirt or friction on the shutter drive gears this will happen, please check the shutter movement by removing the lens.
I think the extent of the instructions is on the Nikon USA web site. Here it is
"The Nikon MB-40 Multi-Power Battery Pack accommodates eight AA (alkaline, lithium, or Ni-MH) batteries, or the Nikon EN-EL4 Rechargeable Li-ion Battery.
The MS-40 Battery Holder comes with the MB-40. With the MB-40 attached, film can be advanced as fast as 8 fps.
When using the EN-EL4 battery, the Battery-Chamber Cover BL-3 must be used.
The MB-40 is also a vertical grip, and features a vertical grip shutter release, an AF start button, and Multi-selector and Command Dials for more comfortable and responsive shooting."
On page 256 of the D-90 users manual it says that ERR indicates a camera malfunction that can be cleared by releasing the shutter. On my D-90 when this occurs, I have to turn the camera off to make the shutter release. Sometimes, but rarely, I have to remove and reinstall the battery to get the shutter to release.
The manual also says that if this error occurs frequently or persists to contact n authorized Nikon service center. I suggest that you contact Nikon tech support at www.nikon,com before you contact a service center to see what tech support advises. I have heard of people resolving this problem by upgrading the firmware (camera software). Nikon tech support can tell you if this will help.
This information works for my D-90 and could work for your D-40
hiwhen you say shutter does not operate, it mean too general to answer. could you provide more detail?I will give how does shutter work. First, you press shutter button, it will activate two switchs (one is focus and meter and the other is release ) Second, mirror goes up and opening shutter curtain move up. Third, closing shutter curtain down and mirror down and picture come out. Of course there is also aperture control unit sequence.
Try to take off the battery and reset the camera. You can also try to remove the lens and check the mirror opening..see if there is some thing stuck there. You can try to click the shutter while the lens is removed. If this procedure didn't work I suggest calling Nikon for further repairs.
