A tale of woe . . . .
I have a 55STW60 (W meaning the European version) bought in June and I can report to you that the IR/burn-in issue is alive and well
in this last series of Panasonic plasmas.
I ran-in my set for 250 hours with random TV content, almost always with contrast levels <50, zoomed in, so no logos.
I decided that, after the 250 hours, I was going to enjoy the TV in a normal way, and I was looking forward to it!
I had downloaded a couple of calibration settings from different sources to try out and see what the picture would look like.
I did so over a couple of hours, looking at the resulting picture, copying settings, etc.
Soon thereafter I was watching some normal TV and suddenly noticed what looked like 2 burned-in (or IR) areas upper left and lower left corners.
Oh, sh*t, I thought, I'd really hoped this model (make that, set) was not very susceptible to this any more, given the newest technology and the run-in of 250 hours.
I looked more closely and I could read "Viera" upper left and "return" lower left.
And it hit me . . . this was from the settings menu
and must have occurred while I was applying the calibration settings!
I checked, and sure enough, there were the two words in the settings menu, in bright white on a black background.
I was in disbelief - - and certainly very disappointed - - with the realization that I had been creating what looks to be a burn-in just by adjusting things in the settings menu. How crazy is that?
I must say, it is a tribute to the colossal stupidity
of the Panasonic engineers to create menus with such strong graphics on black (if you don't have some video constantly running in the background, which no one said you have to), the contrast levels of which you can't reduce
, and still warn the owner not to leave stationary content in the picture for an undefined time to prevent IR/burn-in!!!
But . . . anytime you want to change any kind of settings (which you occasionally might be inclined to do), you need
the settings menu!
This really is kind of insane, and makes me understand the demise of plasma technology far better than before.
I used the screen clear utility for a couple of hours and it seems to have gotten better (in that you can no longer clearly read the words, as at first), but tonight, after watching a movie and some TV programming, it is still clearly visible that something is there.
So, at this point, I don't really know if it will ever entirely disappear (which I sincerely hope it will), or if I now have my first genuine burn-in on my new TV, despite 250 hours of being careful, trying to prevent just this precise situation.
I do know I don't have a chance in hell of Panasonic's support in this situation . . . they would certainly consider the "artifacts" not bothersome enough to take any action, and would say the manual warns against leaving stationary graphic content on the screen, anyway . . . making it "my fault".
