Black screen on canon powershot a1200 can see the symbols and takes black pictures

Did you try to press the display button several times? You then switch between different modes, while shooting and while playback. One of the modes is screen out.

Nice HandmeDown - I checked Amazon for review guide and they had 1854 positive reviews.
The Button next to the black screen is the master button that switches from mode to mode .. like from the screen to the viewfinder (that's above the black screen) with 2 lights.
If this is your first digi camera then it's a big jump.The camera will need a Memory card (unless your nephew from Sydney left that as well) - the batteries will need a charger .

Camera switches on but no display on screen it is black. when switch on camera screen shows canon logo and beeps then goes black on image shown on screen


The black screen problem means the lens sensor is spoiled due to over exposure to heat. Its better to give it to cannon service centre. If your camera is under warranty period its well and good they will replace the lens sensor for free of cost.

Thank you

Have you actually cleaned the contacts or are you just looking at them and they "look" clean? Clean them with a cotton swab lightly dampened in rubbing alcohol.

It most likely was a short in the repaired lens that caused the sensor to go bad over time.

I have been shooting with Canon cameras and lenses for many years and I do not always turn off power before switching lenses. It is not a big deal.

Panasonic DMC-TZ1 operates in Playback mode only


The position from the dial wheel is not corresponding with the electrical position. If you can do it by yourself you can adjust it and tighten the midscrew from the dialwheel

When I try to zoom, screen goes black and "E18" appears in bottom corner

I won't say this is a solution but to prevent the lens retraction E18 message which seems to be common with Canon zoom lenses, I put the extension tube on mine. Sometimes I put a polarizer lens on it but usually I just leave it on to protect the lens when it is on. I have dropped it (on the carpeting at home) and never had a problem. If you have a Canon with a zoom lens, get a lens hood for it ASAP!! My wife's A520 has one on hers too. No problems.
There are lots of other places on the web with suggested fixes. Keep looking and keep enjoying this camera. Merry Christmas all.

Cannon zoom sd870

hi have you tried removing the battery for couple of hours so it can reset any settings that need to be set back to default it only resets camera memory not settings you have changed but this can sometimes solve the problem your having.

Also when you switch camera on and then press zoom when the camera switches off does the lense go back inside the camera as normal or does it reamin out.

when you switch in on do all the other buttons work like can you take picture and can you access all the menu if you can then take it off auto if its on auto then see if this let you use zoom if not then the chances are their is a fault on the zoom button either jammed could be that the lense motor has come out of line with zoom button, is the display clear when you go to take picture without adjusting the zoom is it still possible to take pictures
