a hour hahaha no that won't burn a image think about how many football games you watched and that score been up there? or a widescreen movie those lines been there for 2 hours don't worry about image burn...... except if you leave it on for a day or longer.... again why are you leaving it on for so long? if you playing and music and not paying attention to the screen just turn the tv off and listen to it if you have it hooked through a amp....

Ok, dude, it doesn't work quite like you think.

It's CUMULATIVE.

So let's walk through an example shall we?

Burn in is dependent on differences of an image.  In other words, if you displayed an all white or an all black screen for 3 weeks, you wouldn't really notice the change.  A high contrast image is the worst.  So let's say you display a white X on a black background.  Now let's say it takes 48 hours for that image to burn in.  That means, if you leave your TV on with that image for 48 hours straight, you'll notice the shadow image burned in.  It also means if you leave that image on your TV for 1 hour for 48 days straight you will see the same shadow burned in as if you left it on for 48 hours straight.

Understand?

How long does it take?  Well, again it depends on the image.  A white X on a black background might burn in in just 24 hours.  I can tell you I saw burn in due to a paused game on a rear projection TV after only 12 hours.

Also, burn in is somewhat relative.  I mean, the longer you leave that static image on the TV the darker the burned in shadow will be.  How dark does the shadow have to be before you consider it burned in?

Yeah, the example I gave was 12 hours because that's how long my friend left the image on their screen.  It could be less, but I haven't seen that.  So figure if it took 12 hours to be a certain darkness of a shadow, than in 6 hours it probably would have burned in a shadow that was 50% as dark as the one he got.

And did your friend repeatedly leave the same games paused?  Cause like I said, it's cumulative so it wouldn't have had to happen in a single stretch.  If he left that game paused in the same place for only 30 minutes a day but did it several times a week, that would make those shadows appear.

I think burn in happens a lot easier than people think.

For the record, there are only two display technologies that do not suffer from burn in.  DLP and LCoS.  Might be something to look into when purchasing your next HDTV.
