On one 42" 77 model I saw in the store, when you put up the "menu" on the screen there was very faint "line banding" across the screen. When you exit the "menus" (turn the menu "off") the banding lines would go away? I have not noticed that on any other current Panasonic?

Yellow banding on Panasonic PX75U
Recently purchased a 42" PX75U. Overall im pleased with it after replacing a snakey PX60.
The only major issue I have with it & ive noticed it on recent music videos where the background is grey I get yellow banding. Ive also noticed watching 24 on interior scenes with banding coming off the lights in the scene.
Is this normal for this TV as I was thinking of testing another one to see if it has the same issue.

I also noticed this on my PX77U recently purchased set. I had a calibration disk that had a gray background and whenever I accessed the TV menu to adjust the settings, I would see faint rectangular shadows to the right of the menu rectangles. These extended to the edge of the screen.
I thought my TV had a problem, so I took my calibration disk down to HHGREGG where I bought the set and explained the problem. They put my disk in their DVD player and all of their TVs were displaying the gray background. And guess what, all of the plasma displays would display these rectangular shadows when accessing the menus. Some showed it more than others. It mostly depended on how dark and solid the menu colors were. It showed up more when the menu bar was a dark color like black or dark blue. It was even happening on the 1080p screens.
This image was also being displayed on their LCD screens. When accessing their menus, the problem did not occur.
This must be a limitation of the plasma technology. I have also seen this happen on CRT displays.
I'm surprised that I haven't seen anyone else comment on this anomaly.

It is known by many names and I believe the most common is 'line bleeding'
Every display technology currently available has some sort of 'issue' so one must ultimately decide what he or she can live with. I rate these problems from in order of annoyance:
0.Poor Blacks
1.Rainbows
2.Silk Screen Effect
2.Clouding
4.Vertical Banding
5.Line Bleeding
6.Poor Screen Uniformity
7.Image retention
8.Reflective Screens
Pick your poison. plasma for some is the best compromise.

Which of these are related to LCD?
