    Question Panasonic Toughbook CF-29 Blank Screen

    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.

    Screen worked after replacing then went dim

    I have a new ASUS GL laptop that I spilled a few drops of liquid on the side of the screen.

I replaced the screen without a problem and it worked great for a few...
