After 6+ years of flawless performance my Mitsubishi WS 65511 appears to be missing the color green . When I watch say Golf the grass is a weird shade of brown and theres alot of pink. Any idear of what it could be ? Where do I start ? I've searched this fourm to no avail. I'm not afraid to do my own research, just need alittle help getting started. I'm new at this , but i'm a quick study, Thanks !
