Have plasma TV manufacturers solved the "burn in" problem?

Answer 1

Plasma has phosphors, which are essentially like a paint, which glows when bombarded with invisible ultraviolet light. CRT displays, and plasma as well, especially CRT based projection TVs, are susceptible to burning. This usually happens with extremely bright, high contrast, non-moving, or repetitive pictures. CRT based Projection, and Plasma are not well suited as data displays, or security camera monitors, etc. Newer video games have high resolution graphics, and have screen savers, virtually eliminating the problem. If someone walks away, leaving the display on, it should not burn. Shortly after 9/11, I had the distasteful job of informing some people that the manufacturers of their Projection TVs would not replace the burned CRT(s) under warranty. The very bottom of the screens were yellowish while watching a movie. The blue CRT seems to burn the hottest. They had their TVs on CNN, or other news channels, 24/7 after the disaster. The bright news streamer at the bottom burned the CRT. If you tend to watch, or leave your set on all day just for noise, on these channels, you should consider another display type. While LCD is immune from this problem, it is generally not as bright to begin with. Also consider the viewing angle; Plasma seems the best. Another solution is DLP, Digital Light Projection, which is immune to burning. This set produces a superiorly bright, sharp, and high contrast picture, with a wide viewing angle. DLP displays do not hang on a wall, they are similar in dimensions to CRT Projection TVs. They use a high intensity lamp, which you guessed right, will need replacement at some point. Prices are as varied as other pros and cons. Knowledge of these, and an awareness of how you plan to use the sets, will prepare you for the decision. Don't forget environment. If the room you plan to watch TV in is extremely bright, or the seating arrangement requires a wide angle, nix the LCD. Also, sheer size alone dictates which of these types are best suited, and affects price drastically. Lastly, compare warranties, asking what will and will not be covered.
Last thought: On occasions, where you'll leave a set on all day watching a channel like CNN, you can turn the contrast down, or use one of the picture presets. This should protect the set in these events.

Answer 2

There isn't really a problem with this. As long as you have images moving on your screen "burn in" isn't a concern. The only time you have to worry about this is if you have still images on your screen for a longer period of time. If you turn your t.v. off when you aren't using it, you won't have a problem.
