LCD screen is a very important part of Canon 7D. But, some people have faced problem with the screen. Some have failed to turning on screen back after turning it off once. It is a very easy function to turn it on. But, you have to know the procedure first. First you need to select mode you want you use. Then you have to set it drive mode. Now, you can see the screen to be turned on. Be aware of turning on next time. I always recommend that you know every function of the camera and know how to implement them. Then you will be a great photographer one day.
