Stuck with Black Screen HELP

I don't know whether to post this on Apple Support or Windows, so I'll try both.

I accidentally lowered my brightness on windows 8.1 bootcamp to 0 and the screen turned black. Now I can't see anything and can't increase my brightness because 1. I can't see anything on the screen and 2. the fn keys don't work on the windows side so I can't fix it that way.

Restarting isn't helping because I see the windows logo starting up but then it goes back to black when the log-in screen comes.

Is there any way to fix this without re-installing everything??? PLEASE HELP

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

Try Resetting the PRAM

OS X Yosemite: Reset your computer’s PRAM

Try Resetting the SMC

Resetting the System Management Controller (SMC) on your Mac - Apple Support

Try Booting holding the Option key. Maybe you will be given the option to boot OS X.

Try booting into the Recovery Partition (holding Command-R)

shine a flashlight through the Apple logo and can you see the login screen?

This might indicate a LVDS cable end that plugs into the Logic board.

You can take it in for a free 'Apple Service Diagnostics' test
