Check the site linked below, and see the screen shots of defective LCD TVs, Surf it with patience. This should be a panel fault I assumes. http://electronicshelponline.blogspot.com/
HI:
This maybe due to a faulty T-Con board, this is what I would replace first, since this is the mose inexpensive part in the set, if this does not solve you problem then it is possible that your panel is odefective and needs replacing, if so then it is cheaper to buy a new television.
I'll do my best!
Well there's a little test i need you to do, when you have that green haze on the screen selesct the menu guide and if it also shows the green haze you will need to replace the video board, and if you have na LCD tv, you will need to replace the optical block .
Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.
The most common problem for this complaint is contaminated coolant for the picture tubes. If you look directly into the three picture tubes you will probably see a haze in the blue one. This is fairly common but requires a knowledgeable service man to take care of.
SOUNDS LIKE YOR GREEN CRT NEEDS TO BE REPLACED OR PERHAPS A SMOOTHING CAPACITOR ON YOUR 200V LINE IS OPEN CIRCUIT,PERHAPS YOUR CONVERGENCE ADJUSTMENTS NEED TO BE RESET.
