We have a Proscan 50" Projection TV. A T.V. repairman told us it was the HV (Horizontal Vertical) Splitter causing this problem and tried to find the part for us. The part for our TV was too hard to find though and we ended up not having ours fixed. Our T.V. is 8 years old though, and Proscan is discontinued. Maybe you'll have better luck finding an H.V. Splitter for your TV. Of course, you'd need a professional to install it for you. Good luck.
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
