Screen display i dropped my phone, and now when i turn it on, the backlight behind the keys comes on, but the screen is blank. can i get this repaired, as i have important numbers and pictures on the phone.......

you want to make sure that the brightness is turned up
you can do this by going to settings > wallpapers & brightness > then turn the slider up

if this isn't working it sounds like something is wrong with your screen like the backlighting going out

The following applies to Acer Laptops...

If the power indicator is lit but nothing appears on the screen - The computer's power management system automatically blanks the screen to save power. Press any key to turn the display on.
If pressing any key does not turn the display back on, check the following....
1. The brightness level might be too low. Press Fn and the right cursor key to increase brightness level
2. Display device might be set to an external monitor. Press Fn and F5 to toggle to the internal display
3. Backlight might be turned off. Press Fn and F6 to turn on the backlight.
4. If the Sleep indicator is lit, the computer is in Sleep mode. Press & release power button to resume.

change the strip of display

Are both displays blank, or only one? Is there any backlighting coming on? Any cracks visible? Was there any damage (dropping, etc.) that you remember around the time they went blank?

If you determine that your phone is actually turning on, do the other functions of the phone work? In other words, can you dial a number and hit "Send" and successfully make a call? Can you get sound out of the external speakers by pressing the little "speaker" key at the lower right of the inside keyboard?

If everything seems to work and the ONLY problem is the displays being blank, it is possible to replace the display module. If you have some electronics experience, and you are considering doing it yourself, see this thread for a little more detail about my experience (I did it successfully.) But you'd want to know that the display is the *only* problem before committing to replacing it.

Otherwise, there's not a lot of repair you can do on these things yourself.

if can go in setting and go to black light click it and hit turn off

Well, first you will have to check your options, if you can read it enough to get in there.  You may have the backlight turned off.  If the backlight is not turned off, then you probably have a bad backlight and will have to take it to your provider to get it fixed.  Replacing a screen/backlight is not something I would attempt to do unless you are certain you know exactly what you are doing as you can render the phone completely useless.  

More than likely you will need to replace the LCD screen. The backlight may have burned out making it blank or it the LCD connector may have come loose.

A new LCD screen runs about 15 dollars shipped from ebay.

The W580i LCD is easy, easy to replace. Probably one of the easiest I have ever done.

Check out the following link for instructions on replacing the LCD display and links to buy the screen.

the problem is in display...better change ur display and use it...

I have managed to fix the problem by doing a software update.
I stumbled across the solution..........I had the phone connected to the computer when I started it in the 'boot loader' screen as opposed to just turning it on. This time the computer recognised the phone was connected and through the motorola software update program I was able to update the software and the phone now works fine.
BTW I did lose all my address book, messages etc.
To start in the boot loader screen hold down the * + # + pwr keys all at once.
