laptop screen display

I do not have much experience with latops, but a friend asked me to look at his Toshiba 1555 CDS laptop because the sceen is almost all "white ". By that I mean that it looks like a desktop monitor with the brightness turned all the way up. On the screen I can see the icons, but they are very faint and somewhat blurry. Is there any adjustments on a laptop for contrast, brightness, etc.? Or has anyone ever repaired or replaced the screen on a laptop? Or is it worth it?
Thanks very much,
Tom

 

I have a Toshiba laptop not the same model. In the manual it shows the following keys to press to adjust the brightness. May be the same for that laptop.
Fn + F7 = increases screen brightness
Fn + F8 = decreases screen brightness
Toshiba has the user guide for download.
