I have a Canon Power Shot A570 IS and everytime I turn it on the screen is all blurry and the shapes can hardly be made out. This is how the pictures come out too.

You should be able to access the manual if you follow this link. https://camerausermanual.net/canon-powershot-a570-is-manual/

hello!!

You can get them here : http://usa.canon.com/cusa/support/consumer/digital_cameras/powershot_a_series/powershot_a570_is#BrochuresAndManuals

Hope this solves your problem.

Turn on auto focus and when you are taking a shot let Auto-Focus adjust the blurry image in the viewfinder beforeyou take a shot. If you do not know how to do it please let me know and I will give you detailed instructions.

Sai.

The lens block is faulty it can be replace by a technician

When hand-held shooting, shaking will cause blurry. So when the shutter speed below 1 / 60 second the vibration warning will appear, open the flash, up shutter speeds, vibration warning disappeared.

Please see the following comment:

The Display button manually turns the LCD display on or off to save batteries. If you accidentally had turned the LCD off, It should only take one press of the button to turn it back on and leave it that way. As such, it's not you but the camera. The A570 IS is relatively new. Your camera is likely still under warranty. If so, contact Canon for warranty repair (see the following link):

I have seen the same problem with my A570 IS. When pointing to a window or in an outdoor environment the iris within the lens closes completely within ~3 steps (look at the lens when pointing to the window). Therefor it is not a LCD issue at all. The fact that you can still take a photo with a closed lens rather suggests that the iris controlling software is corrupt.This will most likely just require a firmware update.I hope Canon will soon provide the software online.
