The problem you are encountering is called a "dead pixel". Every ccd has several dead pixel, so it is quite normal. But I agree that it can be annoying.
The solution is to map the bad pixel and to substract them afterhands.
Go to http://chdk.wikia.com/wiki/Main_Page and download the latest firmware for you camera here http://mighty-hoernsche.de/.
It is a supplement to your camera that will open hundreds of possibilities, like making time-lapse recordings, doing your own scripts, shooting RAW,...as well as a feature for removing bad pixels.
All you have to do is to read! Yeah, I know, there are lots of things written :p
More specifically, here is the "how to use badpixel removal" explanation.

My fujifilm camera has a problem when i take pictures in bright conditions the picture taken becomes pinkish whats the possible problem?


Wrong white balance setting maybe? Manual white balance only works in P, S, A and M setting, so switching the camera to Auto should solve the problem. If pictures are pink in Auto as well, the problem could be electronic.

No image/sound mesage when I try to view pictures taken


I would try formatting the card, and trying with new pictures. If that does not work, you may need a new main board. The main boards on that model are prone to problems. You will have to decide if it is worth fixing, if formatting does not fix it. If you want to sell this camera, contact me at: mrfixitmark at comcast dot net I can use this camera for parts.

No setting can cause white spots on the picture, this is a fault.

By the way you can reset settings on this camera to initial state by simply removing and putting back camera batteries.
Alternatively you should have a reset command on camera settings menu.

My opinion is that this is a fault and not a settings problem.

Typically there are three kind of faults that can cause this problem:

1 - Dirty lens or water inside the lens:
The lens may be dirty inside, for example because of water condensation on internal surfaces, this will cause blurred dots or black dots. The lens must be taken apart and cleaned in this case.

2 - Defective CCD sensor.
The CCD sensor is the chip that detects the picture, if you get well defined white or colored spots on picture that is probably a defective CCD. I think this is the more likely in your case. To fix this the sensor must be replaced.

3 - Defective video chip on internal board.
This can cause any kind of problems, however it is quite unlikely.
It is an expensive repair.

Camera won't take new pictures


you need to download the pictures off the camera. Once they are downloaded and erased from the camera, you'll be able to take pictures again.

RED DOT


Hi,

If the dot is not visible in print, but only on the camera's screen, the its only the LCD that is faulty.

If the dot is visible on screens and in print, then yes, it could be the sensor. Try taking pictures without the digital zoom. Chances are the dot is only visible with the digital zoom because the picture is interpolated.

If all else fails, you can try cloning out the spot in an image editor on the computer.

Unhappy with the quality of the pictures


Is the white dot in the viewfinder? I could see that getting very annoying so I'd probably send it back. The shots I've taken indoors with the flash on the c2100 have not had any problems with over exposure. There are both exposure and flash compensation settings in the camera, make sure you haven't changed them by accident. If this is your first digital you have to get used to the way the images look, it's not the same as film. At first digial images look "soft" and more grainy, more so if you look at them at 1:1. I usually view them so they are about 8" wide on the screen, or about 1:2. As the number of pixels goes up the difference between different compression levels becomes less noticable. If you shoot in 640x480 mode you'll see a difference between high and normal. At full resolution on some shots you'll get better color on SHQ over HQ. And TIFF is rarely any better than SHQ.
