I need help, I have had my D40 for 3 years now, and suddenly it went black after taking a picture. You take a picture and its black.. No problem with the lens nor the mechanical part. It takes the picture but its just black...I don´t know if it is the sensor....or what..

Sorry you're having trouble! The D40 is such a nice camera. Can you tell us what exactly goes black? The viewfinder - you cannot see the scene thru the viewfinder/lens anymore? Or the LCD on the back does not show the image review anymore? Is the picture still recorded onto the SD card and you can take more pictures? Some more info will help us give advice.
By the way, this should be posted in the D60/D50/D40 forum where fellow D40 owners can see it so you might get more help there.
Well the problem is that when I take the picture (yes I can see through the lens) , and I want to see it, the LCD shows the review but it shows as if I have taken a black picture. I explain: I take the picture, it sounds perfect, speed and aperture, zoom are in order. After I have taken the picture I check the Histogram and its blank, the axes appear but no other line (the sensor?). In fact the picture is recorded on the SD card and I can take more pictures.. but all in black. I took off the lens and I did the exercice without it it works fine but it records black images.
Another thing I notice is that the display format, which I have always had as Graphic for all the Digital Vari-program modes, changed suddenly to "Classic" for some modes.
Welcome to Nikonians! Sorry to hear of your problem. What do the images look like when downloaded and viewed on your computer monitor? Are the images black or correctly exposed? Good Luck and Enjoy your Nikons!
The simple things to check: 1. The exposure mode. If it was inadvertantly changed to Manual (M) with a fast shutter speed and or with the aperture stopped down that could easily be the cause of your problem. You might also want to try different exposure modes and see if there is a problem with the mode dial. 2. Exposure Compensation. Though less likely, check the Exposure Compensation and make sure it is set to zero. 3. Is the viewfinder dark? If yes, Make sure the lens is fully mounted and locked in the mount. If it is still dark, the problem could be the stop down mechinism on the camera or a sticking diaphragm in the lens. 4. Is the shutter opening? Place the camera in Manual exposure mode. Set a slow shutter speed like 1/2 sec. Remove the lens. Turn the camera on and release the shutter while looking into the light box. The mirror should go up and the shutter should open for a 1/2 sec. then close. If everything is working normally, and the images are still black, it is time to send the camera in to Nikon Service or a Nikon Authorized Repair Station. Good Luck and Enjoy your Nikons!
No, the viewfinder is not dark... I can see through the mirrors and the lens.
The shutter is opening...and closing perfect. I tried with different speeds and I tried it also taking the lens off,and I can see that the mechanism is working fine. That is why I think that maybe the sensor is the problem... Is this common after 3 years of use? The problem appeared suddenly after taking a picture. Maybe it is something electric given that at that moment the display on the change to classic automatically...
If the sensor is the problem, is it better to buy new one or to change camera?
Marty thanks for the help, any suggestion will be welcome.

I would not call it common but like anything else, electronics can and do fail as it only takes one bad solder joint or component to fail.

Since it is out of warranty, you might want to call one of the Nikon Authorized Service Stations and ask them for a ballpark estimate or price range for the repair. Again it could be the sensor that is bad or maybe just a loose connection. Then base your decision on that information. Good Luck and Enjoy your Nikons!
