A factory reset does not work. I called customer support, and they told me they couldn't help me, and that I needed to call tecincal support, but when I called tecincal support, they also told me they could not help me, and they suggested I call customer support.
I need the help of the community. From what I can see, the only way I am going to get my tempature settings back to their default state, is if I find another person who also owns a kdl-46ex500 tv, and they go into its factory mode > Color Tempature settings, and share with me number values so I may copy them. I all other TV's of the same model, would have the same system settings.
