There are actually 3 projectors inside, each handling one of those three colors which, together, make all the other colors. This is called "out of register" where they are aiming slightly differently. These need to be adjusted.
If the problem happens using different input and devices, then it is either the terminal circuit (input/output connectors) or the processing unit in main board. The terminals are unlikely the culprit if problem concerns different inputs.
I imagine that the picture is not properly B&W (gray-shades) but some kind of reddish, bluish or greenish picture as the LCD will process picture using RGB (red green blue) channels instead of CYMK (cyan yellow magenta black) like CRT TVs.
Test the TV using an external aerial. You will notice if the channels have the wrong color even from static.
Use different inputs, different cables and different devices. beware of SCART cables, the SCART contacts are very easy to break. A defective cable will loose picture. Better testing using AV cables and component cables. AV cables are red/white for sound and yellow for video. If the two-wired yellow cable does not work, then the TV is faulty. Other test can be done using component cables. Component cables send the three red-green-blue signals on different cables, hence testing is simple. Test swapping cables and see if TV tone stays the same if color tone changes the problem were the cables. Test also using at least two different devices (e.g. one DVD player and one TV receiver or a playstation).
If you find that the TV is defective call the manufacturer at the number listed on manual. If the problem is that one or more RGB channels do not work the TV main controller board must be replaced.
There are several possibilities in that area. The Picture Tube (CRT) is driven by three different video signals. One presents the Red, one the Blue and one Green. All other colors are derived from a mixture of those three colors. The greenish tint could be a sign that the green gun is being over driven or the Red and the Blue are less than adequate to create a normal picture. Sorry to say this but the most common problem that causes that symptom is the emission in the "gun" assembly inside the picture tube is declining with age and hours of operation. Sony Picture tubes are typically good for around 40,000 hours of use. I don't recommend replacing the picture tube. If the set is more than 5 years old I would suggest that you start looking for a new set.
I know this is bad news but I am just telling what I know the most likely scenario that I have seen in 35 years of TV service.
Good day sir, your inquiry about the green lcd screen can be caused by several things. 1. The monitor/tv produces 3 colors, red green and blue, the tv mixes these three colors to produce the picture. a loss of red and blue produces this green screen. so check the cable, specially the red and blue jack of the component inputs, and the red and blue cable. 2. there may be loose contact on the signal cable. try using the video input instead of the component input. 3. the dvd player may have the problem, check the player component out jack. a loose jack port can cause these problem. hope this may help. thanks
Looks like you are using Component cables. There are five cables. The first three cables are Green,Blue and Red. These are the ones that are molded next to each other and are the Video signal cables. The other two cables are Red and White and they are the audio cables.
First to correctly hook up these cables you need to Connect (Match) Color for Color. (Green to Green, Blue to Blue, and Red to Red. To tell if you have correctly connected the Video cables is to look at the screen. If the picture looks ok (Normal with no colors missing then you have connected the video cables correctly). If you see a missing color meaning red, then switch the Red cables. The picture should be ok now. The remaining two cables are the Red and White cables. The "Red cable" is for the "Right" audio input and the "White" cable is for the "Left" audio Input". If all is connected correctly then you should have a good picture and Left and Right audio.
