Yellow-green tint of images on Nikon CoolPix P7000

Hi there:
Some symptoms of a defective CCD include distorted images or abnormal colors, scratchy purple lines, blank or black pictures, and/or black videos with good sound being recorded on the camera's flash card.

A CCD problem would explain the lines on your pictures and the lines on the LCD (since the CCD is used to feed the live image). CCD (Charge Coupled Device) is one of the two main types of image sensors used in digital cameras.

When a picture is taken, the CCD is struck by light coming through the camera's lens. Each of the thousands or millions of tiny pixels that make up the CCD convert this light into electrons. The number of electrons, usually described as the pixel's accumulated charge, is measured, then converted to a digital value. This last step occurs outside the CCD, in a camera component called an analog-to-digital converter.

In order to correct this issue, the repair facility needs to replace the CCD. This is not something you may do on your own; check this article for additional details:Bad CCDs. This, isn't a good new, but hope helps to solve it.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

The yellow is from having the color temperature set wrong. There is either a temperature setting, a light type setting (sun, fluorescent etc) or both. These will change the color hue of your pictures.

You have a white balance issue. Somewhere in the menu system is a command to alter the white balance - for indoor shooting by artificial light (i.e. light bulbs) it should be set to 'tungsten'. Using flash would overcome this, but the pictures would look very harsh and unnatural.

Incandescent lighting is yellow and shows up that way on photos. That's why digital cameras have white balance controls. Usually, auto white balance works ok but, sometimes you need to go into the settings and choose incandescent white balance to remove the yellow as you take the pics.

To get back to factory settings follow the instructions for the S4's manual. They can be found here:

From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
