Make a "Genius" appointment at an Apple Store to have the machine tested. Back up all data before you go.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Thank you for your help, but my machine continously don't work. I can´t use time machine neither the firewire target disk mode work's well. I finaly reinstall lion and the upgrades by target mode but in the reboot the screen turns off to black again. I think I'm gone try to install leopard, may be it's a conflit with the video card and the lion system. The problem is inconsistent. One time the screen works well, and later it turns to black without no reason. A friend tell me that my be is a problem with the video card.
I don´t now.
Thank you all again
