When I turn on camera the red light comes on,but I can view pics...that area is black?

I recommend you to call Canon on this.
Call this number and have them see if they can help. 1-800-652-2666
They may want to have a look at it and then will give you an estimate (they will pay postage both ways if they repair it, otherwise you have to pay the return postage, if you decide not to repair it at all) which you can turn down or opt to upgrade should the camera cost too much.They can give a great upgrade price on a completely repaired camera of your choice of what is in stock. These are called a refurbished cameras, which means it comes with everything as if it was new. Also a warranty, may depend on the model.
