Well I will explain how this happened. About 3 month ago the TV died and I purchased a new one. However, one day I decided to mess around with it and took out the board where the power goes in, checked all resistors etc, also changed IC STK711-550 to a new one which I suspected would be at fault. This wasn't the case but I found the 1ohm 15 watt resistor was dead and changed it, this made the TV fianlly turn on.

However, when it did, and this is after 3 month of not using it. I noticed right away that when watching movies S-video or Composite, all the faces were green, so I checked the Tint (hue) feature which I suspected was all the way to green, was actually dead center.

I had to move the bar all the way left which should turn all the faces Pink, but instead when I do that only then do the faces start looking normal (not green), but center/and to the right faces are green.

Not sure what to suspect, what should I be looking at if everything is more green then it should be?

Also, on the left side of the screen, there is a green Hase that comes out about 1", so if you're looking at the TV when watching a movie, on the left side there is a green shadow that sticks out about 1 inch which you can still see throw but it's there like a cloud over an image.

I should note that for some time, only Panorama/Cinema/full feature works with this wide screen TV, if set to "normal" you can't see anything, it's all just screwed up. I'm not sure if this has anythign to do with the green hase to the left and greenish faces I'm seeing since it was like that for a long time, but the green stuff started happening only after I turned it on, 3 month ago all was fine.

I tried to be as detailed as possible, and hopefully someone knows what should be replaced/adjusted maybe.
