Color wheel on this TV was just replaced about a month ago. After the service, I notice some smudge (?) or different shades of color on face, or on background, specially black/blue etc. I have tried changing color settings but haven't helped? I have called the Service tech. to come back and take a look at it but just wanted to ask any of you, if you have any idea?
Could it be color wheel? or bulb going bad? Please let me know.
