Sounds like a hardware issue. Make sure your settings on your computer are not causing it. If its not your settings then it is a hardware issue with the monitor which sadly means you will have to send it to the manufacture or someone who does hardware repair.
One thing to try is to connect your Inspiron up to an external monitor. You can plug in any kind of monitor, but you might have to toggle to the external mode:
Hold down your function key, then hit the LCD/CRT key. If you have a good display on an external monitor, then you are going to need either a LCD inverter or new LCD. They are not too hard to swap out, the inverter costs about $15,it is mounted in the lid, below the LCD, and the replacement LCD about $80.
The best way is to buy a special microfibre cleaning cloth for LCD monitors. Very often the same cloths are used to clean sunglasses so you may already have one of those. Do not use any cleaning liquid. Rub the screen very GENTLY with the cloth until the prints are gone. You can rub fast but remember not to press too hard or you can damage your monitor.
To use the external vga connector of a laptop, you have to activate it. In many notebooks it is Funtion and F7 (Fn-F7). In your notebook it may be F5 or F6, look for a monitor sigh in the F keys.
The activation may sometimes rotate in sequence , ie, External + LCD, LCD, External... and so on.
Just check that your monitor is not set to power down(Control Panel> Power Options) and check that the 'Turn Monitor Off' Power Scheme is set to never and turn off any screensaver to see if it still goes off.
