(Please forgive any English syntax errors it's not my first language)
whew I just finished reading the whole thread (skipped only a few posts)
I won a LG 42PG20 in a contest and I have it for 2 days.
I haven't really tried it yet (just tested it a few minutes) because I wanted to be well informed before.
So from this thread I realize that the main problem seems to be the station logos.
IMO the stations/network/channels are to blame. What they should do is pretty simple:
1.Display a transparent logo
2.Move the logo (with fade-out fade-in) regularly (bottom right, bottom left, top right and top left)
3.Display no logo at all
Now in a case of ticker (stock market, sports results, etc) I guess there is nothing to do unfortunately.
Finally here is something I found while searching for "tv station logos plasma" on google.
It's an article in which the Plasma-tv producers talk about burn-in.
(Can't post the URL since it's my 1st post).
Samsung's answer is almost hilarious
we recommend that you limit your viewing of stationary graphics and images, such as the dark side-bars on nonexpanded standard format television programs, stock market reports, video game displays, station logos, web sites, and computer graphics and patterns to no more than 5% of the total television viewing per week.
5% ? Are you kidding me ? What's the % of channels that display a logo ? I would guess that it's a lot higher than 5%. Basically you can't watch TV with a Plasma according to Samsung.
Since I bought a LCD (only 26" though) a few weeks before winning the Plasma I think I'll watch TV on it and reserve the plasma for movies.
But then again even movies can cause problems with the black bars.
Maybe I'll just use the Plasma as a decoration.
I'm just kidding of course
