I have a Panasonic LCD model TC L42U25 that is one year old. I had to reboot my cable and when I turned the TV back on it lost the color red and green. The TV now has a hue of yellow and dull and vivid blues. I tried through the menu to readjust, to no avail. Help! Many thanks.

Check the connection to the TV.

Is the TV's menu affected? Does this happen with another source, like a DVD player?

Thank you. I unplugged everything and then plugged everything back in and rebooted cable and all working again.
