I've owned a Panasonic PT53WX for about a year. Recently, on light backgrounds, I've noticed a very light vertical bar, about 5 inches wide, running along the left side of the screen.
A service tech came out and, shifting through the RGB guns one by one, showed me that the image was actually a burn-in, on the blue gun, of the product description window that QVC uses on the left side of its screen.
My question is...QVC regularly shifts off the window, so it's rarely in position for more than 5 or 6 minutes. It that enough to cause a burn-in? If not, any thoughts about how the blue gun got burned? (There's no doubt about what was burned. I can read the QVC info. And no cracks, please, about my wife...the QVC addict).

Have you checked your contrast? It's usually set at 100% by default for store viewing and if you don't change it you will get burn-in exponentially quicker.
Not sure about the blue-gun thing, but is the QVC bar blue? That might explain it.

1. Blue phosphors seem to burn more easily than others.
2. A blue burn causes patches of yellow. Yellow is the absence of blue.
3. A burn in 6 minutes is inconceivable if the set adjustment is anywhere near correct. It must have been longer. If they show the same image for 6 minutes twice per hour then 6 minutes is not the number that matters.

exaaactly.....
just because they switch it some....
it is the total percentage of viewing time that the logo is actually displayed in the same place....
which actually confuses me here.....
"QVC regularly shifts off the window"
Could you explain this for me?
if they "shift" the logo equally....
you would think there would be burn ins in all the other locations it shifts to???
i think I am just not understanding what you mean by "shift"

I don't think he's talking about a logo. It's the blue background on the left side of the screen, where QVC has text describing the product for sale. Just solid blue.

Sorry, I wasn't clear. The box with the product information, (sometimes blue, sometimes yellow), is always in the same location on the screen. It is rarely on the screen for longer than 5 or 6 minutes at a time but it is also rarely OFF for more than a few minutes. So, in the course of an hour it might have a cumulative appearance time of 30 or 40 minutes. If the set is on QVC for three hours it could be there a cumulative time of more than two hours.
All of a sudden I'm understanding how it could burn in!
