Just received a mint condition Nikon Coolpix S4 swivel-head digital camera off eBay. Installed new AA alkaline (Duracell) batteries and a new 1GB SD card. From the firt time I fired it up this morning, all...
Without some detailed information on how the unit processes video vs. still images, it won't be possible to say for sure, BUT....
The video resolution is processed at a much lower megapixel setting than still pictures. It may be that the defect in the sensor that is causing the lines is on a section of the sensor that is either not used in video mode, or that the software is processing out the defect when it doesn't need all the pixels to give you an image. I think the first is more likely. In video mode, the camera has to run at a lower resolution so that the electronics can store information fast enough to give you video, so it uses a lower resolution. Since it's using the same sensor, it has to either ignore some of the pixels or just not sample them.
If it is the sensor (this is most likely but can't be sure without testing it), then the only way to correct would be a new sensor. It could also be a bad wiring connection, but either way you'd need to get inside to fix. That would be expensive.
I think you should try to use a lower resolution setting and see if maybe that will eliminate the pixels that aren't working. You won't be able to get the highest resolution from the camera, but megapixels are overrated. If you can run it at 3 megapixels or more, you'll be able to do just about anything with it.
