Sometimes all you have to do is press the left or right adjustment buttons, one will bring up contrast adjustment, the other brightness.
 Otherwise simply browse through the menu settings.

You will not find contrast controls for most laptops. This is a funtion that you found on most desktop CRT monitors. However, xp and vista has some features on smoothing and such of your viewing icons in the basic right click on desktop/select properties

This is a board level problem.
If you can replace capacitors then check/change C405,C406 and C407.
