Canon power shot SD750 can't take pic with flash

Tv is "shutter priority" mode. The Canon SD cameras do not have that mode. Instead see Fix 5A of the below link. A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

the flash only covers a certain range and the built in flash has quite a small range. so lets say its dark in the room and you take a shot of a person they probably look really bright but the background is pretty dark, thats pretty normal and its better not to use flash, now in the auto mode without flash it will be using a higher "ISO" number to get you brighter shots indoors. shots may look slightly grainer but it means its brighter and the 550d handles low light pretty well.

in auto mode you have no control over the ISO but put the camera into P mode which is basically auto but with access to more controls which you can override. now next to the shutter button there is an "ISO"button. experiment with the different numbered setting (100 being low 3200 being high) and you will see what I mean

Bring up the pic you want to delete and press the button with the garbage can icon...follow the on-screen instructions.
If all your pics are safely downloaded to your computer and you want to erase the entire card, go into the menu and find "format"...follow the on-screen instructions.

You have a defective LCD screen.

Press cursor-right (marked with a lightning bolt) to bring up the flash menu, then select the lightning-bolt-in-a-circle-with-a-slash-through-it icon.

There is a cold solder on the flash unit. If you want to DIY, here is a tips for your reference
How to fix a Canon SD750 with intermittent flash problem

The manual says the flash range is 1' to 1.6 feet with setting the ISO speed to auto.

Yes we can repair it.

I had same problem. Called Canon and found out A40 is not compatible with Vista so there is no driver. But you can download pics to your Vista by purchasing USB Memory Card Reader/Writer you can find at Walmart for about $12.00. You put your Flash card in device and has USB that plugs in computer for downloading pics.

You may download Canon software from here.

Bear in mind that you don't need to use Canon software. The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.


Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program such as Picasa.
