When I snap a picture and the camera has finished processing the picture, the monitor goes black. It used to be that I could snap another picture - but I'm not able to see anything.
I changed the batteries twice, cleanned out the inside and reset all the settings. The camera is less than a year old - HELP!
It always does that while it's powering up the flash again. If you're saying it doesn't come back after a few more seconds, that is a problem. Or maybe by that time, the power saver kicks in. You can tell if the power light starts blinking. Then you just have to press the shutter button again to turn it back on.

Does the menu show when you press the MENU button? Can you see your pictures when you press the Playback button (right-pointing triangle)? If so, then there's nothing to fix. The D40 works as SLRs have worked for half a century. There's a viewfinder which allows you to frame and compose your picture. The LCD monitor is for menus, camera settings, and picture review. LiveView, which allows you to use the monitor for shooting, is a recent development, which Nikon introduced into their cameras with the D3 and D300, both introduced years after the D40.
I see that this monitor has a DVI input, in additon to the VGA input. I suggest getting a suitable cable to use the DVI input, to see if the fault replicates. If it doesn't, you have identified the problem - an issue with the analogue signal processeing circuitry in either the monitor or the computer. The monitor's auto sleep analogue circuitry, for example, may not be sensing a signal, and going to sleep. BTW, if you use a DVI-DVI cable, you avoid the video signal ever going through an analogue stage, and the image will also be purer.
The picture board on your monitor is bad, since it goes

I believe the power led button is still on while the screen goes black, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes black after that

You can try this. Open the cover (Unplug the monitor and leave at least for 30 minutes before doing this). See whether dust is there. If there is dust, get a 1" paint brush and gently remove the dust with the brush. Always sweep the dust away from the unit. If black dust is present around certain cables and around the flyback transformer (that black box covered with aluminium plates), use a soft cloth to wipe them (do not wet the cloth).
*Make sure you dont turn those rings on the back of the tube while wiping the the dust.
After cleaning the dust, replace the cover, connect it to the PC and check. You will have a brighter picture!
Video (picture) must be constantly entering a monitor for a monitor to continue to display a picture after it self tests (goes on for a second or, two) Your monitor is fine; check it using another known good computer.
I ended up fixing my problem, but I'm not sure what the solution is. I had some faulty electrical equipment that I was using to power the monitor (220V to 110V converter and a bad power strip) and I got rid of them. I was using the converter because I moved to Israel and I thought I needed to feed the monitor only 110V, but I now realize that the power cord for the monitor has a built-in converter that accepts 220V input. Now the monitor is plugged directly into the wall and is working fine. Try using a different power source (maybe the wiring or plug you're using is faulty). Good Luck!
