I got cooking oil inside my A720 Canon and now is fuggy. Is there a way to get rid of the oil without removing the lense, if not how do I remove it

Add just a cap (tbsp) of cooking oil to any washer or dishwasher with excessive suds. The oil will be extremely effective in removing the excessive suds and will not leave any residue.

if you go to my computer there should be a drive for your camera card there

If you have done all that was listed in your description "normally" error 99 is an electronic malfunction however, a camera firmware update may also fix the problem. Canon has these updates on their site and it can prove beneficial in this case. One of the offices I look after had two Canon 30D's great camera and they used them hard for two and a half year and at 80,000 frames I had Canon Canada replace the shutter and shutter button which is a weak link in the electronic chain. The shutter release button gets oils from the users hands down into the circuit and causes faults as well. Most times you can see a slight build up of oils in the switch between the button and the camera body. Don't bother trying to clean it the stuff is already down inside. Try the firmware update first then if the problem is solved you are good to go if not then it's service time.

Consider NOT connecting your camera to your computer.

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 Canon ZoomBrowser or any other photo cataloging program.

go into where you protected them and click on pic and the scroll down and hit unlock or unprotect and that will remove the protection on the photo.

I wouldn't advise that you do it yourself unless you did your homework and know how to take it apart. I would buy a air can dust blower and try to get rid of it like that, followed by a lens brush to clear away extra dabre.

If nothing works, take it in for a service by your local camera store or into Canon.

Hi The front lens will screw off after you remove the front cover ring and you can clean it

there is, but it is a pain. you need to remove the top, the cables off of the main board, the 3 screws on the main board, the spacers on the dvi connector, the rear screen (by it's screw), the fan underneath the board, the colorwheel guard, the 3 screws holding in the optical engine, then the optical engine. now you can remove the 3 screws for the lens and remove the lens. now if you can remember the spacing on the focus/zoom rings, remove the screws and unscrew the lens barrel and clean it. now put it back together. it might be easier to find another used lp70+ and swap out the parts.

Hi,
