Hey, My macbook pro 2.4 is having video problems. For the past month the lcd on the macbook pro seems to work sometime and doesn't sometimes. Whenever I plug it into an external monitor it works everytime. What could cause this? Is it a motherboard issue?

Any help is greatly appreciated

thanks.

if the video works fine on external monitors, then you know that the video card and MB are cooperating;
there is a power supply for the backlight that might be dying or the majority of the lcd assembly, which can be messed up from the connectivity bus to the actual pixels themselves
i think you can replace either the backlight PS or the whole screen assembly
or just keep using an external monitor
