Hello everyone. I just purchased a Mitsubishi DLP and immediatelty turned down brightness and contrast.

Somehow, and I'm still figuring out the Mitsubishi interface, the contrast was at 100 percent for a few minutes (less than ten) before I noticed and turned it down. Now, on my DVD menu page (mostly all blue) I can vaguely see a burn in line running across the screen, and I'm wondering if it's something I did or not.

That's not the only thing. Something else is worrying me (maybe I'm just paranoid, since my last TV had burn in), and that is I haven't been able to figure out how to make the black bars (top or bottom of screen) fade. I thought most sets would allow you to change the color of the bars?

What's really bugging me though is that I turn down my contrast and brightness, so my TV can do a channel scan (during set up) but the menu automatically resets my brightness, once it starts scanning my cable box, and the background color is this hideously bright blue that I'm worried will damage my set if I allow the channel scanning to continue. My understand is that channel scanning (for this set) can take several minutes and I'm worried that the extremely bright blue background color will cause damage to my new DLP set.

Is that possible and does anyone know if the Mitsubishi sets allow you to change the background color or the bar colors?

Thanks!

you are paranoid. DLP does not suffer burn-in.

you are paranoid. DLP does not suffer burn-in.

what he said. you don't have to worry about any of that nonsense as dlp does not have the possibility of burn in. watch what you want any way you want, and pause the screen for weeks on end just for good measure;)

You need to read how a DLP television works

http://en.wikipedia.org/wiki/DLP


there is no possible way you can have burn in.

the very simple explanation of how DLP works:

Basicly a white light shines thru a spinning color wheel which is reflected off the DLP chip and projected on to the screen.

There are no phosphors to burn.

Keep the contrast cranked as high as you want.

You may or may not know there is a light bulb in your set that will burn out at some time which will have to be replaced if you want to watch TV again.

I hope you are not affected by rainbows.

The rainbow effect is explained in the wikipedia link above.

Enjoy your new set, don't worry about burn in, find the owners thread for your model here on AVS for info on tweaking your new TV for the best possible picture, it is probably one of these threads, you did not mention your model #

C'est impossible. There is nothing to "burn," as the earlier posters told you. Perhaps you are looking too hard. If you do see such a line, then it indicates some other problem that may be an issue, but it is not burn-in.
