Welcome to Apple Support Communities.
If I understand correctly, your MacBook Air shows a blank gray screen after upgrading to OS X El Capitan. If you haven't already, try adjusting the brightness of your display as described in the article below.
About the screens you see when your Mac starts up - Apple Support
Blank screen
After the power-on self test is complete, your Mac sends a video signal to your connected displays. The display screen might appear black or gray at this point in the startup sequence and the display's backlight should turn on. If you don't see an image appear on your screen after a few moments, try turning up your display's brightness. If you're using an external display, make sure it's connected properly and turned on.
So long.
