When I boot up, the screen shows the boot screen as expected, with 'Panasonic' and Centrino logo, F2/F12 options very readable; there seems to be no problem with the display at this point. After the boot screen closes, however, the screen stays lit, with the LED shining brightly from the bottom of the screen. There is nothing displayed, as far as I can see. Windows XP is installed, and I can bring up the Windows Advanced Options Menu with F8, but any option leaves me back at the blank screen. I've tried changing all applicable options in BIOS to no avail. Fn+F3 is a no go. Booting from CD leads to same issue. Any ideas would be greatly appreciated. Tyvm.
