When I turn it on, nothing appears on the screen?

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

Try pressing F11 and leaving the laptop plugged in for a few minutes, sometimes things like this take time.

You may need to replace the batteries.

Well try cleaning the game packs out with quips and rubbing alchal the game packs could just be dirty then I had a problem with my sega it would just show a black screen when I turned it on so I cleaned out the game packs and it was fine after that the worst case is that your sega is on its way out let's hope not but lukie games sells sega products too.

Looks like a CCD image sensor failure a common fault in digicams these days. Point the camera somewhere and blindly take a shot. Open the image on your computer and see if it appears all dark. If it does then its an image sensor failure. On the contrary if the image appears properly then your LCD screen is the culprit.

Try 2nd Down Arrow. Your contrast may be turned up too high. This can appear to happen with new batteries.

you have to repair or reinstall your operating system

First make sure your phone is fully charged. Then check...
It may be the storage card - if you take the storage card out it will boot up and you can put it back in. - pain in the a## but it may work. Or Try taking the SIM card out, boot it up, turn it off, replace the card, and turn it on again.
Last resort is a hard reboot. If you did a hard reboot and nothing happened then you did not do it successfully. To do a hard reboot.

- keep the power button pressed down for 1 - 2 seconds and then release the power button while still holding down the two soft keys. Keep holding down the soft keys until a black screen appears and prompts appear
- now release the soft keys and follow prompts
- if you dont see the black screen with the reset option, pull the battery out, reinsert it and repeat the above steps
- when you see the black screen with the reset option, press the Send button to confirm the reset.
