|   Regarding Projection TVs, and still images.. | toddstock
Feb 25, 2002 5:51 AM | | I am getting ready to purchase a Pioneer 64" HDTV Projection.... It will be my first projection, as I have had 35" Tvs....
I know it is not good to leave stills on the screen, but I have one concern... My wife uses the guide on DirecTv quite a bit, and that has me concerned... Will that burn out the TV... If so, what do most of you do with projections?? Do you not even use the Directv guide??? Any comments are greatly appreciated... |

Usually, on a menu like that you're scrolling through it anyway so the pixels are constantly changing. Again, I wouldn't be that concerned about it. Good Luck with the new set.

Feb 25, 2002 2:01 PM | | I listen to the DirecTV music channels and do turn off the TV after finding the music channel I want to listen to (for hours). However, I was just wondering....about how long would it take to burn someting in?
Also, on the black bar issue mentioned below, note that some TV's (Hitachi at a minimum) use a grey instead of a black bar to help to avoid the burn thing. The disadvantage is that the picture does not appear to be as bright (because it is next to grey bars instead of black bars) but is is suppose to prevent (or minimize) the burn problem. |

Feb 25, 2002 3:02 PM | | The gray bars do to minimize the chance of burn in, but it is still possible. I don't think there is a time frame for when burn in might occur, I suppose there are different factors. I just try to keep logos off the screen if I plan on watching the station for an extended period of time. Most of the time I can use my theaterwide modes and enlarge the picture so the logos and scrolling bars disappear. Just be cautious of it and you will probably never have a problem. |

Feb 25, 2002 9:21 AM | | Things to be concerned about. As stated above your wife probably isn't staying on the menu for hours at a time and she's probably scrolling so pixels are changing so probably not going to harm anything. However, things to be aware of. If you use PiP the outline of the box is static so the outline can burn in to the tv so when you use this feature move the box around after a while if it's been up there for a long time. Also things with ticker tapes like some news stations and ESPN and other sports stations can burn in so don't leave the NasDaq ticker tape on for hours at a time. I'm sure you've heard the warnings about video games as well. Also if watching movies or tv with the bars (top and bottom for 4:3, sides for 16:9) be careful about burning the bars into the screen. Don't take this the wrong way and be scared out of buying this tv. The burn in usually doesn't happen if the person exercises a little care just look out for the things I mentioned. |
| Just turn down your Contrast, and you should be allright. | SmokE
Feb 25, 2002 3:29 PM | | Since burn-in is directly related to the screen light output (lampfoot), then by turning down your Contrast you should reduce this problem greatly. The trick to be happy with low Contrast setting is to keep your ambient surrounding lights low. This way, you also prolong the life of your TV's CRTs :) |
