My laptop is on but the screen is blue and won't go to the desktop


A Mac that shows you a blank blue screen instead of logging you in may be afflicted by a malfunctioning startup item. Most people have a number of programs that start up whenever you log into your computer, and it's likely that one of these programs is causing issues. The startup item is unable to load, and so it causes the rest of the computer to hang.
In order to get your Mac past this hanging blue screen, you need to boot into safe mode and figure out which startup item is causing problems. The Apple Support article "I see a blank blue screen when I try to start up my computer" tells you exactly how to go about this procedure. Basically, you must remove all your startup items and add them back in one-by-one, rebooting each time until you find the one that causes the hanging blue screen.

After a few seconds the screen goes black


You need to restore the phone to the factory defaults. If this doesn't work, you'd have to bring your phone to someone that can update the phone's firmware.

Sandisk sansa e250 blank screen


If you have a blank screen but the blue lighted ring is on. Remove the back, the battery, remove the 4 tiny screws. pop the front plate off. Carefully remove the circuit board from the case starting from the bottom. On the back of the circuit board you will find a smaller circuit board that is plugged in. This board sometime becomes partially unplugged do to rough handling. Press this board back into its socket carefully. Reassemble the unit and everything should be fine.I repaired 2 Sansa E280 unit from Woot grab bags with this method.
