Hp mini screen is blank

Remove ALL media, DVD, CD, USB, etc. Unplug, remove battery, plug in, reboot. Any change? If no, do a system restore /recovery. You didn't supply your HP mini Model number so I can't be presise.

Almost all of the HPs Mini laptop screen issues are related to the internal video card/motherboard. hopefully you still have the laptop under warranty.

hp mini screen is black after i turn it on...any suggestions?????

Please have the bois reset...chances are the bois could be corrupted..

Try this: Remove Mini from A/C power; remove battery. Hold power button for 10 seconds; reinstall battery & A/C power. Try starting normally. Your netbook doesn't appear to have an external VGA port, or I would suggest trying to connect to an external monitor. Your monitor back-light may be burned out.

that true, u much change new lcd

Glad you got the help you needed.

Try holding F11 while booting, sometimes this triggers the recovery partition.

It appears the video cable connector needs to be seated properly, it may be loose. The connector would be located near to bottom of the screen on the motherboard between the hinge and the top edge of the keyboard.
Depending upon the model of the laptop there is a plastic panel which houses push buttons and indicator lights that is located between the top edge of the keyboard and the bottom of the LCD screen. There are screws at the bottom of the laptop and possible screws on the back next to the hinge securing this panel. This panel would also have small plastic retaining clips locking it into place. You need a thin blade to lift this panel up, be careful not to crack the panel.
Once you remove this panel you see this video connector and cable. the connector may also be held in place with a screw and plate.

It seems to be u have problem with ur RAM ..Try to change it
