The Video Controller works off of the RGB principal. RED/Green/Blue pixels. The mix color is dependent on the formation and density of the pixel and rates. When one or more colors are absent the only functioning color will dominate, and it is Green in your case. The screen liquid crystals in Red and Blue are failing and only a screen replacement will fix the situation.
There is fault on the chroma section and can be related to the board . Also a proper alignement cannot be ruled out unless the fault is seen in detail and so it is best to seek a consensus and estimate before you proceed , not to tamper unless there is a clear direction from the observation.
Have a very close look at the blue and see if it's perfectly uniform across the whole screen. If it is then altering the hue or colour temperature settings in the menu may help. If it's not then either there are heaps of pixel failures (appearing as small rectangular spots) or degradation of the polarisers (green may be affected more than the others). If you show the menu, do the white areas appear bluish. If the lamp is very old then colour changes start to happen.
you must re-adjust in the RGB (Red-Green-Blue) setting. depending on the brand of your TV, because there are set manually from the TV (you must open the cover of the rear of the TV). and there is a set directly from the remote only, with the open "factory settings", then you can re-adjust RGB color, especially green, not too dominant with the other colors (RED-BLUE). how to set is that you need to neutralize the color, (color TV sets to zero level) so that the image becomes black and white. if the green is too dominant, then Decrease the level of Green Bias or Green Cut off/ G-drive.
the blue gun is not working properly which explains the dominance of green and yellow colors. you need to look after dry-joints on the blue gun circuit board, sometimes oil leakage from the lens may also affect the board
A picture or blank raster viewed from the front will have red marks if a portion of the image path from the green CRT to the front screen is blocked by debris or if the Green CRT is damaged from burn-in or other situations. If green is missing, red dominates virtually any image.
Severe CRT burn-in can occur when there is no sweep signal to a yoke. I have seen technicians removing yoke connectors on RPTVs in attempts to find shorted or suspect components.
Occasionally a damaged TV is sent back to customers as repaired and a service order for a new "fault or complaint" is initiated when the customer complains of the red or green marks or lines.
