All images have suddenly become vignetted. There is a blue/purple fringe around the vignetted image.
Camera has not been dropped, always kept in padded case, never in heat or direct sunlight.
Lens element separation?
Thanks for any help you can offer or directions you can point me.

Recently my Fuji S20 pro pictures started to look like purple and green blurred water colour images. Sometimes there is horizontal lines in the pics. like when your printer stars to get low on toner. I called customer service. They said to send it in. My cost. They will send an estimate if I want it fixed i pay. If I do not and want it back they will charge me $25 to get it back. Or they will keep it and recycle it. How kind of them!!!

That is known as 'purple fringing' and is usually the result of the sensors and/or the lenses in your camera not being able to handle higher contrasts or over-exposure. Scientifically it has more to do with the how the camera sensor responds to the available light spectrum. (see: https://en.wikipedia.org/wiki/Purple_fringing) Have you notice it is generally more pronounced where a very bright (white) area meets a high contrast (black) edge (like a bright sky behind a dark or shadowed object)? Best way to avoid is to be careful about the relative light levels exposures when framing the shot---or using a UV filter. There are many photo editing programs which can help eliminate purple fringing in post production. Have a read through: http://www.photoforbeginners.com/news/tutorials/how-to-remove-purple-fringing-from-your-photos.
The set needs to be focussed and reconverged. The red and blue images combined make a magenta/purple image. Adding green makes it white. Depending on the type of TV, if it's a CRT projection TV then there's an electronic focus control for each of the three tubes as well as the mechanical adjustment of the optical lenses. Given the description, then I'd have a look at the electronic focus first. A sudden shift in focus suggests that something in that circuit has given out. This would cause the red and blue images to go soft enough to create a halo around objects on screen.
The term for an out-of-focus purple "ghost" image on a photograph is "Purple Fringing."
This is fairly common in Digital Photography.
In order to minimize instances of purple fringing you may incorporate the following:
Avoid shooting with big aperture (Small /f number) in high contrast compositions.
Avoid overexposing highlights (e.g. bright sky behind dark objects).
Shoot with a UV/Skylight Filter or a Circular Polarizing Filter. These protect the lens and also help to Get bluer skies and cut glare off reflective objects.
You could also use Post-processing to remove purple fringing by scaling the fringed color channel. This can be done in an image editor like Photoshop.
These suggestions will help in minimizing the instances of color displacement for you.
I will look forward to your feedback and positive rating.
These screw on the front of the plastic lens adapter and adjust the focal length. On the side of the adapter lenses it will quote the ratio. My wide angle says 0.66x so just multiply the range of focal lengths by this figure and you will see that it adjusts the camera zoom accordingly - making the image wider and probably also increasing the depth of field (what is in focus). Similarly a 1.5 tele will inrease the range of focal lengths to make the lens "longer" eg higher magnification , useful for astro photography - shots of the moon and terrestrial long distance work but detracting from the depth of field, eg the range of distance over which objects are in focus will be reduced.
The wide angle will allow you to come in close and get WIDE objects fully in-frame- hence "wide angle", while the telephoto will give you better overall maginification of the image but will probably increase the MINIMUM focal length - eg you may not be able to focus on objects closer than >2m (instead of ~1).
The screw-on adapter lenses I found were cheap in a Jessops sale use a 52mm thread, while the S5500 provides a 55mm internal thread. I use an appropriate 55mm to 52mm step down ring adapter. There is slight vignetting (shading around the edge of an image) at certain combinations of zoom, but generally these are very useful accessories.
As these are adapter lenses on the front of an already powerful 10x zoom that must be optically compromised at the price of this camera, there maybe some colour fringeing around bright images. If you want a better solution you really need to get a DSLR. Overall a good solution for the price.
If you are using an accessory telephoto lens, you will need to zoom out to about midway or further in order to fill the image frame.
An accessory lens called a "fisheye" may not cover to the edges of your image. Even wide-angle accessory lenses may show vignetting (a darkening of the corners) or unsharpness in the corners of the image.
It is called 'purple fringing' or chromatic aberration. It is quite common with digital cameras, especially those with small sensors. Sending the camera in for repair would not help at all. It can be removed, quite labouriously, in photoshop. Usually it is very seldom so obvious that it would require corrective work. When it is, it is often only in a small part of the image making it not that time consuming to fix in photoshop.
