SD750 turns on, battery good, but can't take pic with flash. The camera turns on, the battery is powered up, but when I press down on the button to take a picture, the camera won't work

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.

Press the flash button (right on the multiselector, marked with a lightning bolt) repeatedly to cycle through the various flash modes. To turn off the flash, select the lightning bolt in a circle with a slash through it. Don't forget to turn it back on later if you want it to flash.

Press the Playback button (the right-pointing triangle). Hold down the FUNC/SET button and press the MENU button. Use the arrow keys to select English, then press the FUNC/SET button.

Did you accidentally press the DISP button on the back of your camera (the bottom button). This manually turns the screen on and off to save batteries. Try pressing it once more to see if that corrects the problem.

Hi

Your flash is defective, or the mainboard is defective and cannot control the flash. The only way to figure out which is the problem is to start by replacing the flash and see if it works.

You can probably find a parts camera online and use it to fix yours, if not let us know and we can help. We are an affordable digital camera repair business.

earlier i posted solution in similary problem. maybe help you this.

solution is good batteries, Ni-Mh or Lithium, rechargeable only not alkaline. but...problem is how long you watch pictures on lcd display or how much is flash in use. if always by shooting pics used flash that means that you can with best batteries 30, 20 or less pics shooted. and of course, if you connect camera with pc, how long is cam on? just transfer pics on pc and turn the camera off. the best solution is use the card reader for pics transfering.
if is flash off, it's possible to shot 120-150 pics with Ni-Mh. with lithium i don't know, maybe 500 pics. don't use camera lcd for analysing pics it's just there for short preview.
with alkaline batt., very low quality, i shot 30 pics without flash.

i shot also very good pics at night without flash. nikon coolpix L15 can do that but you must have more praxis. alkaline batteries shooting!
after 3 pictures on display is message: warning! the battery is exhausted. what you can do? turn the camera off. wait about 10 minutes. turn the camera on, you can shot 3 or 5 pictures and than turn your camera off again.
you can repeat this few times and you be lucky if you 30 pics captured:)
REMEMBER: all this goes without camera flash!!!
flash and every zooming use more battery power! and that was all magic:).

Hi
There are several things that could cause this. 

1- Check the battery door indicator switch under the battery door and beside the memory card slot. Is the little black switch damaged or missing? Try pressing down gently using a pen it with the door open and then press the power button. Does it turn on?

2- The fuse has blown and needs to be replaced. Offhand I don't recall where it is on the SD750 PCB or how hard it is to solder on a new one (depends on if its tricky to get at or not). Good thing is fuses are really cheap.

3- Other power problem with the PCB due to corrosion or impact damage. The PCB or 'motherboard' of the camera will need to be replaced.

hi,let me just inform u that the macro mode is only for outdoors.So on the side of the camera u will find a sliding switch.Just slide it to the opposite direction to turn off the macro mode.Since u wanted to take pictures of jewelry pieces,turn on the flash if u have one and then take a closeup shot with good lighting conditions.If its too bright then use only the flash,if u r not satisfied with the quality then use only lights and then take a pic.Still face any prob plz get back to me.

hi emery,I guess the batteries are drained out in the camera.So just take out the memory card if u r using any.....and then try replacing the batteries.Turn ON the camera only with the batteries in.Check if its working fine.....If yes then use a different card.If no then plz get back to me.
