We shouldn't have to do that with this TV. Or any TV. Yes i know a calibration gets 100% out of it but i shouldn't have to spend extra money because the color is so far off from normal. And i don't think a calibration can get rid of the green patches.
I spoke to a technician about this. He said pioneer still has replacement displays if he can't fix the issue. What are the chances this happening on a new one?
