Picture go on and off the sound is great.

D40s are well known for flash failures...in 3-shot burst mode, due to charge time of flash circuit, 1st pic good; next 2 black. Battery life greatly reduced in this mode.

This sounds like a CCD problem. You will need to get the camera checked at a repair shop.

You need to change the white balance to tungsten lighting.

in night shot mode always greenish yellow tint ahead. it 's common

number1 be sure that you,re using energizer lithium batteries only.they,re the best.2 because these cameras have such a small flash and its placed in the front of the camera instead of the top,they,re not really made for night shots.but from 3-5ft you should get great pics at very low light.just put it on auto,and ignore the low light message,press down and hold for 2seconds then release.you should get great pictures this way.good luck,hope i helped

no there isn,t.but these cameras do not have enough flash to take great pictures at night,for one you cant be to far away,two you have to have a subject in range of the flash,other wise all you get is darkness.but at the most 10ft is the farthest you can go and still get a great shot at dark.also use auto mode when taking pictures,because it adjusts to light-dark etc.i know this because i have the same camera and its awesome,plus im a photo technician and ran a photo lab for 3years selling digital cameras. good luck,hope i helped

Hi, Mark here see if I can help.

Sound like your camera is set to night photography.
Try resetting it to Auto or sports when shooting in daylight.

Hope this fixed ya! need more help comment back.
Please rate. Good Luck!

have you tried it with the led flash mode

Sounds like the picture tube is going bad or there is a screen voltage capacitor bad in the sweep power supply.

There are ways to deal with this problem. As others have said, your camera appears to be normal. Consider using "dark frame subtraction" to successfully employ long shutter speeds. The technique involves capturing two images using the same exposure time and the same camera temperature. One of the images is your picture. The other (the "dark image") is captured with the lens cap on, or other suitable way to block all light. Then using one of the more sophisticated photo editing applications, "subtract" the "dark image" from your picture. This technique will dramatically reduce the noise, because moist of the noise is deterministic, but is highly dependent on shutter speed and on CCD temperature. Of course you can use flash at night, but only for subjects that are close enough to the camera - not for a subject such as your stjernehimmel 2 photo
