My camera used to take really good pictures,but lately they have lines across them and look like red neg.what could have happened.also the camera turns off if you don't use it for a few min

You need to go into the menu and go to the menu with a camera as the icon. Scroll until you find "IS mode". You can choose various settings but the best is "Continuous". That way, your camera always compensates for camera shake.

I had the same thing happen to me last November. Canon has a recall of sorts on a wide range of older cameras. Apparently there is an issue with the sensor. Canon will fix the camera free under this recall program.

Here is a writeup of my experience with Canon's customer support (good):

Good Day;
You may have bad picture tube or convergence problem. Good Luck, big IRIShH.

Probably a problem with the chip - this model had a recall and free fix...contact the manufacturer for details

It's the CCD in the camera. You can take into a repair shop and see if it can be replaced.

Nothing to do with any chips being faulty.
The clue is in the video....
The video function does not use the shutter.
The shutter has become fouled.
Unfortunately this is a major strip down to clean the shutter

Yup, it is a common problem. The shutter is jammed. I bet outside pictures are really overexposed. The horizontal lines are caused by the electronic noise created by the shutter solenoid trying to move the shutter. If the cameraq is no longer under warranty- Sometimes, you can free up the shutter by banging the camera in a hard surface like a desk or table. (Do this carefully, don't get carried away) If this doesn't work, you will need to replace the whole lens unit. this is best if the warranty is still good.

sounds like capacitor problems or a possible ccd problem or driver problem .Its time to send in the unit for an estiamate. Cont # is 1-800-NIKON-UX , 1-800-NIKON-US Good Luck
