  • Assuming that you have not experienced a failure in a circuit, your television needs to have the colour adjusted properly. Green hues are a very common problem - the green has been factory-adjusted to make grass look good, but it makes people look slightly nauseated. This is one of the many reasons why the NTSC system, used in Canada, the US, and Japan, is called Never The Same Colour. There are a number of controls that can be used to adjust the contrast, brightness, colour, and other parameters of the television picture. These may go under different names on different televisions: colour may be called hue, for example. This control can be accessed via the remote and adjusted as needed. However, most televisions come out of the box set up the wrong way for home viewing. They are configured by default to show a punchy image in a brightly-lit showroom. This can be adjusted, with care, and with some practice. However, there are alternatives... I use a calibration DVD with every television in my home: "Digital Video Essentials" from Joe Kane Productions. There are other, similar, products on the market. The Video Essentials disk includes an RGB (red, green, blue) filter that is used with the test signals to calibrate the picture's colour balance. Most televisions only provide a single colour control - the colour or hue adjustment previously mentioned - so it is almost impossible to accurately calibrate all of the colours properly. Almost all televisions have a slight bias, usually to the red or green. With the right tools and a little work, the results can be quite impressive, particularly if you take the time to make all of the adjustments.
  • RedJohn is correct. I should add that in the RGB system that the Greenish/Blue hue is caused by a fault with the RED. I.e. Red fails and Green/Blue tint produced. Green fails and Purple tint produced. Blue fails and Yellow tint produced. The likely cause of your problem is with the electronics, I would suspect a solder joint within the T.V or a failing of the primary graphics interface within the T.V. I don't know whether your T.V is LCD or tube technology.
