My screen is very dim, my pictures turn out clear and light but i cant see anything on the screen, even stored pictures. I have to put my memory card into a different camera or upload my pictures to see them. I dropped it lightly when it was OFF shortly before this started happening.

This problem is only related with back light in lcd screen and has nothing to do with ccd imager chip as explained by previous expert.
LCD screen is not getting enough voltage to lit back light to show its image thus you get darker image.
I suspect back light circuit section at main board got physical damage due to drop of camera. Visual check by qualified camera tech is needed to fix it.

The could be the Backlight/CCD image going bad in the camera, if the output video is so dark you cannot see it or the screen is black you have a CCD image issue, Now if its just dim this is a back lighti ssue with the lcd. all after witch need to be repaired unfortunatly, You might also be in power save mode so check that out is well, also check the birghtness in the menu as well.
