Could be a few issues to consider. The video processing card is faulty. hold a flashlight close to the screen and see if you can see the images. if yes, your powerboard has a failure and the backlight has failed. either way, get a repairman to attend to it.

It could be either, if you can get another LCD screen (same make/model) you can swap to ckeck it out.
You could check the inverter by touching its output and if you get a bit of an electrical shock then you know the inverter is working or check it with a multimeter if you don't like electric shocks.

This is a known fault with r710s but you could try to update your display driver
go to NVIDIA - Download Drivers
Update your nvidia drivers with this link (make sure you're using
Windows 7 32bit) if not go to the nvidia site and let it scan your pc.
After you've done this you should be able to adjust your screen brightness through the windows brightness adjuster.

The T-Con bd or the Main bd is bad. Have a tech check it out. There is no way to check these bds with a meter.

Well, most common failure in the LCD monitor is due to bad caps, worst case will be the lamp assemblies. 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.
So look for bad caps first.
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:
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 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.

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.

Testimonial: "I had already thought of that, but since I couldn't find any notebook beep code charts (there are plenty for desktops, instead) I asked for confirmation. This seems to be video card related. I think I'll just ditch this old notebook and get a new one. Thanks anyway."
