I have a week old G10 that had been working fine. While watching cable yesterday, an ~3 inch vertical area on the left side of the screen started changing. The color went dimmer, it went black, and then went back to normal. Eventually the color went dim again and then was back to normal. It did it again later, and turning the set off and on got it back to normal again. I contacted Panasonic who said if an engineer came out it would be difficult to figure out the problem unless it was showing the issue at that time. He didn't have an idea as to what might be causing it. Has anyone seen this issue before? I searched past threads but didn't seem to find the same issue described.
