edit- I also should note it only shows up on the red screen. None of the others. I've never experienced a dead or stuck pixel. Anyone know if this will unstick. I believe the pixel is yellowish in color.
I don't doubt what you are seeing but it can't be from a dead red sub-pixel. One a true "red" screen only the red sub-pixels will fire. If its "dead" you would see black (nothing) not yellow. In order to get yellow, the tv fires both the red and green sub-pixels for that rgb grouping. So if you see yellow it indicates the green-sub pixel is stuck "on". Obviously, it will look fine on a green screen. On a blue screen that pixel would appear cyan. Most obvious, it would appear green on a black screen.
Green is the worst sub-pixel to have a problem with because your eye is more sensitive to green than any other color. So if a green sub-pixel is behaving badly it should be noticeable (up close) on everything other than a green screen. But you are indicating all other color screens are OK. If this realy the case?
Take a magnifier and look closely at the area. You will be able to see the sub-pixels and you will be able to see what is going on (stuck-on, dead, dirt ...)
In all seriousness, if the only time you can detect this is with a calibration disk, on a red screen, and probably fairly close to the screen then I would just forget about it. If you had multiple faults in a close area or an entire row or large blocks of faulted pixels then its an obvious problem. I have no idea where Panasonic stands on the issue, but I do know that a few years ago most of the manufacturers didn't consider a few dead sub-pixels a "fault". It depended on the color, location, grouping, and overall number of rogue sub-pixels before they would call a screen "defective".
