I.ve purchased a VPCCW21FX unit some 4 months ago...2 weeks ago, when im using it, the screen went blank, i mean, no picture, nor backlight whatsoever, i reboot the unit, still no display right from the moment i press the power button, but the booting proses went fine, i can hear win7 login sound, but still no display on the screen, so i tried to connect the VGA socket to external monitor, push the display off button several times, still no display. tried to find solution on the net, and found that announcement regarding this unit. there is no way i could perform the update when there's no display.
is there any way i could fix this prob by myself, since im working on offshore oil rig, in Indonesia.
Try this: connect a working external display. Press Fn+F7 once, then press enter or Fn+F7 twice, then enter or Fn+F7 three times, then enter to switch display modes between internal, external and both. After each try, press Fn+F6 a few times to increase the brightness (use Fn+F5 to decrease brightness).
If none of that works, there may be a hardware issue. The laptop is still under warranty, so if it is opened or repaired by anyone other than Sony, the warranty might be voided. Sony support may have suggestions. You can chat, email or phone them:
