Can I reset the white balance on a Nikon D7000 camera without using the multi selector?

I know what I'm talking about. I looked into it. It's in the manual under white balance. The manual, however, does not fix my problem.

Here's a photo showing what I'm talking about: http://i.imgur.com/Cdbn4aa.jpg

When I press down on the WB button, a bar pops up. I set it on the darkest level and cannot put it back in the middle because the up button on my multi selector does not work. I'd like to get it back to normal, but have no idea how.

I tried a reset by pressing the two buttons with the little green dots on them. All it did was reset my shooting settings.

Thanks, I'm pretty relieved to hear that, although I hate the brightness being so low. Not sure how I got it mixed up with white balance. I guess because that's where it was in the manual. I really like to use live mode, however. I hate using the tiny little viewfinder. I guess it's because I'm not used to using it. I've used pretty simple cameras up until now. (A Canon powershot and a Nikon coolpix) I also draw on my eyebrows and using the viewfinder smears them. My down button works, it's just the up and right buttons. I set it up so that the main command dial can be used to go through my photos and the menu. So there isn't much trouble. I'm having my boyfriend take off the back plate and look at the buttons to see if he can fix them. They may be simply stuck, as I spilled a bit of coffee on that part of my camera.
