Well, there can be two main reasons for it:

1) Either the brightness of your screen is lessened to a greater extent. If that is the case than you can increase the brightness by pressing FN (Function) key and a key from F1 to F12 based on your laptop setting to increase the brightness. Generally it is F7 to decrease the Brightness & F8 to increase the brightness.

2) If your brightness is alright then there is a problem with your LCD Panel. Take it to nearest Compaq Authorized Vendor for a check up. There may be a lose connection or a fault with your LCD Panel.

SOURCE: I Have a Sony laptop VGN-NR160e. When I turn it

Your back light or the back light power board is the problem. The way you checked with the flash light is exactly how to find out if it is a back light issue. The ghost desktop is the indication as the image is there but just not illuminated. The back light is like the bulb on a film projector. If it goes out the images are still there you just can't see them.

This is covered by warranty if you have any. So if you think you do you should contact the store you bought it from or contact Sony. If you think you have extended warranty that is usually through the purchase store. If you don't have warranty you have to be a bit more careful. The repair cost will be about $100-$150 with most of that being labour as well as any shipping on top of it. So you want to make sure it isn't excessive. On some low end laptops the repair is as much as a new one. Your other alternative is a bit of DIY.

I don't know where you are located so no idea if any of the places that supply parts are close to you etc. If you do a search for "Sony laptop VGN-NR160e backlight" or "laptop repair parts" you will find literally hundreds of sources. This is a job you can do yourself. This link shows you how how to do it on your model. That will give an idea of what you would have to do. This next link is a place that sells the bulb as well as the inverter board. I'd replace both while you have it apart. The bulb is $10 and the board is $19. If you have the tools which is basically a small Phillips screw driver and something to use as a case splitter like a credit card and a drop of glue to put the little rubber screw covers back in place. This next link is for the inverter board and just click along the left side to get to the back light bulb (or search by model).

Those are your options for a bad back light.If you are considering doing it yourself there are videos and other pages you can look at. Instead of junking it or using a external monitor all the time the parts are cheap enough to make it worthwhile looking at doing it yourself.

I have sound but no picture on my Sharp Aquos tv.

Do a flashlight test on the screen. With the TV on shine a flashlight on it and look for a dim picture. If you see it, the ballast board for the backlights is bad. If you don't see any movement, the T-Con board is bad. You can get parts from here and fix it yourself. TV Parts Universal TV Stands DLP Chips ShopJimmy

Why won't it turn on?

While it is on, shine a bright flashlight on an angle across the surface away from you. Can you see any faint images on the screen. If yes, then possibly the back lit lamp / board needs to be replaced.

No picture

If you look very close at your screen (might need flashlight here), do you see the picture as a black screen? If so, your backlight may have died on the panel. Replacing the inverter board will fix that right up unless the tube (lightbulb) has burnt out instead of the board. Both are replaceable.. Check it out.

It's mostly likely a bad capacitor in the main power supply of your monitor. If you're brave enough to dismantle it, look for capacitors that're "crowned", and sometimes even rupture from overheating in such circumstances. You can order replacements from Digi-Key if you can figure out which might be your problem, but I'm not sure I recommend you try this unless you have at least SOME soldering/desoldering skills or a friend who does. You COULD wind up worse off. It's up to you, only YOU know your personal skill level for such tasks. And do I need to say, UNPLUG it before dismantiling? :)

Black screen

Here is a fast test for the inverter in the display. Take a small flashlight and shine it in to the bottom right corner where the windows start button should be. While shining the light in try looking at the screen. If you can see the Start icon then the inverter PS or the FL tube in the display is bad. The least expensive fix is to replace the Inverter. There exist detailed instructions for the disassembly of the display panel as well as sources for the part itself. If there is further problems contact back later.

Black screen that can be seen with a flashlight

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :-
