I have a canon ixus 700 and the lcd screen is blank does not show what i am viewing or piture taken. menu comes up on the screen tho. would any one know the problem thanks andrew

Click the "disp" button. The display of the camera has been turned off in the LCD screen but you can still use the viewfinder, this functionality is just for those who prefer to use the viewfinder instead of the LCD screen.

You have a defective LCD screen.

you need to page through MENU and find section "reset all" - accept. and screen should back on.

did you press the disp. button?

Mine too! Screen works fine in video mode as well. Love my camera and dont want to replace it (have been using the traditional viewfinder), but repair too expensive.

All ideas welcome.

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):

The battery does not work at all/the charger was shut down.

This sounds like a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following two links for more info:

Have you checked the display mode you're in? If you have the display set to off (to save power) and also the picture review time set to off, then you'll just see a black screen. Try pressing the 'Disp.' button below the screen when the camera is on - it should cycle through different settings with each press: Off, On, On with picture info. Similarly, in the playback mode this will show you more or less info about the picture you are viewing.

Even if the display is switched off, if you have your 'review' option in the menu set to anything other than Off (i.e. 2 seconds), then you should see the picture you've taken appear on the screen straight after taking it.

If it's not that, then I don't know the answer....

I know in most digital cameras there is an option buried in one menus to turn display OFF. Perhaps, you can have a look around in the various menus to turn screen back on. Also, there should be another button or feature that allows you to view the shots you've taken.
