It sounds like your "backlight" went out. This is a tiny compact fluorescent bulb in the LCD that lights up the screen. There are usually two reasons for this 1) the bulb burns out or 2) the little circuit board that powers the light fails, this is called the "inverter board" and is either in the "lid" (screen part) of the laptop or in the main base of the laptop. That's why there is a really dim picture. There are two parts of the LCD, one to produce the picture and the bulb that illuminates this picture so you can see it easily.
There's no easy way to test this. You will either have to replace the LCD or replace the inverter board to check. Usually the problem is with the inverter board, which is good because it can be easier to replace and a lot cheaper than a new LCD screen.
You can check HERE to see if any of these guides looks like they might help you replace the inverter. They don't have your exact computer, but they do have several models that are similar.
If you take it to a commercial repair shop it will probably cost between $250-400 to repair. If you contact someone good through Craigslist or some other similar service in your area, you should be able to find someone to do it for about $50+ parts.
