Display turn off atomatic and never start again and after restart and display work

restart can fix display issues. Try restarting your computer and see if the display starts working again.

try unplugging the monitor and letting it rest for a couple minutes. If you have another computer please see if the problem is the same when the monitor is hooked up to that one.

HI

can you try to start up with power key and also press the f8 key at the same time

now can you see anything if you can

go down to and try to click on repair and if that dont work on restart
then start up again pressing the f8
and try last good configuration and if that dont start up correctly then

try to restart again pressing f8 and try to go into safe mode when you probably will be able
to see the screen

and if you can go to device manager
scroll down to find the display
uninstall it and do a restart and hopefully windows will find new hardware and
reinstall the display correctly but it will probably just give you a standard vga driver

so on restart if you can then see your screen you could go to
start
programs/windows updates
check for new updates to see if there is a update for your vga

good luck

Take it back to the service centre

IN A CASE LIKE THIS AND ALWAYS THE BEST IS TO RETURNE IT TO THE DEALER FOR REPAIRS UNDER WARANTY OR DIRECTIONS TO FOLOW TO GET IT WORKING AGAIN. ANDRE

NEED TO CHANGE YOUR PHONE

What firmware are you using? use SEUS to get latest firmware.

Start in Safe Mode & then restore it

If you have the mac os install cd, try physically taking out the hard drive from your battery bay (http://www.youtube.com/watch?v=8c6ckjy-gdY) close up the bay and turn on your mac without the hard drive in place, while the chime is heard press and hold the alt/option key to get a list of bootable devices, ie. the install cd. Select the cd when the cd loads, go to the menu at the top and select startup disk, follow instructins to get your computer to atomatically start from the cd on next restart.

Select the restart option by cancelling th install.
AFTER THE COMPUTER SHUTS OFF IT WILL RESTART, DO NOT LET IT RESTART, TURN IT BACK OFF IMMEDIATELY.

Now take out the battery-bay again and put the hard drive back in. Put everything back together and turn the computer on again. This time it should automatically load the install cd if it is stil in the drive. When it loads the installation you should be able to find a way to either use disk repair to put a startup image back on the hard drive or completely reinstall the OS on the hard drive (which it will recognize now)..

If yu have any other questions let me know i can give you a more detailed explanation if necessary

Restore in SAFE mode to previous date.
