I assume you only found the 4 mount screws in the back... You also need to take off the front silver edging - it pops off with some negotiating, but if you find the right spots and don't pry hard it will come off clean without too much difficulty. Then take out the screws that hold the screen inside and it should drop out.

If some of the pins inside the monitor cable are bent or broken you can losr primary colors and cause this. Check them. If they seem OK try reseating both ends of the cable. If no go, then try the monitor of a differnt computer to see wether its the videocard or the monitor thats defective.

The cable from the Monitor USB input to PC USB output is good? Check to see if you do have 5vdc on pin 1 of the USB connector. Your monitor is basically a powered USB hub when it is connected to PC through a USB cable.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on: Basic LCD monitor and TV troubleshooting guide: Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. 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.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed AOC monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.
