The monitor does not show a light to say it's on or off and no picture appears. It was all working last night. Is it a fuse that's gone and, if so, any ideas on how to fix it?

Hello Dave,

Check the power light, if it is faintly blinking then this link should help you get it going. That model is well known to have a problem on the control board that causes the monitor to not power up right.

This VE155 uses wallwart 12vdc 3.5A power supply, you need to check first to see if it is putting out 12vdc.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Hi there,

First, check to make sure the power cable is plugged properly in the back of the monitor and into the surge protector. You can try a different power outlet, but if you're still having the same problem and the light isn't turning on, it's likely you've either blown the fuse inside the monitor, or you had a power surge and blown something inside the monitor. This happens when you don't use a surge protector and just plug the monitor into the wall.

That said, if the above doesn't work then you have a hardware problem with your monitor and it needs to be serviced.

Try a different video card or disconnect the one you have in your PC and use the VGA monitor connection on the motherboard. If it works your video card is gone.

If the D40 monitor showed you the image while taking the picture, there was something seriously wrong with the camera, which now appears to have fixed itself.

The D40 works as SLRs have worked for half a century, giving you the image through the viewfinder. The LiveView capability, allowing you to use the LCD monitor like a point&shoot camera, is a relatively new development, which Nikon introduced with the D3 and D300 a year after the D40.

Look for bad caps with bulging tops as shown in my pictures here: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VA721/

Please post back what you find.

it seems the lens is bad

Doesn't sound like a virus. Sounds like a fuse or something else is out. A red light isn't good. If the monitor is ok you get an amber light. I would suggest this monitor is gone. Sorry.

It might be that some caps need replacing.

There is a body control module that may cause this issue, it has the ability to be tested, have that done first.
