How do I decrease the amount of green in the picture?
The color on my set has gone screwy, and I've been trying to fine-tune it to get it back to normal, but no matter what I do, the picture is still too green. Perhaps I'm adjusting the wrong things. What do I need to adjust?

Re: How do I decrease the amount of green in the picture?
Unfortunately this model has a bad CRT. If is 3-4 years old and the greenish picture is in all inputs, for sure the picture tube is gone. If the picture is green only in component input check the connections for the blue and red cables.

Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.
actually when JVC tv's turn green the light engine is going bad. I repair lots and lots of these. The engine can be rebuild for about $500 installed. IT is a known problem for us tv techs. I have 1 engine left if you know a tech who can install it. These sell for $300. This fixes the problem which is the green chip color breaking down and smearing. All whites look green. The best way to tell is to turn the color all the way down and see if you still see green tint. It works best on a black and whit picture if poss. but any will do. Usally it shows more in one section on the picture but is green all over. my number is 270-996-7629 if you have any questions.
The problem with the set is that the blue gun has gone weak, and not emitting at par with red and green guns in your picture tube. Turn of the blue screen and get the grainy display on the screen (detach the cable) and enter into service mode to fine tune until you get a perfect or black and white grain pattern.
check your lamp it might have gone bad if not then on these sets the color wheel goes bad if you get junk on the screen like broken bits of info and you might get a weird sound like computer noise then it might be your color wheel it is a small round glass wheel i just checked to see if your model is in this list of samsung color wheel and yes it is
