The Dreaded "BURN-IN"

I have a RCA SCENIUM (model# HD61W140) High-Def. 16:9 rear projection T.V. I have a slight burn in on the sides of the picture due to images broadcast in 4:3 ratio(black and grey bars depending on tv stations). Now my question is: Will this go away in time by stretching 4:3 images and setting the contrast to a lower setting or do I have to get it fixed? The burn-in is very slight.

    Unfortunately, you're stuck with it. Calibrate your TV ASAP with Sound & Vision disk or Avia. At a minimum, use the THX Optimizer found in Monsters Inc, Pirates of the Carib, etc. The effect may lessen over time, but you will probably always be able to tell.

    Basically, you're not wearing your CRT's evenly by watching 4:3 on a 16:9 screen. Your salesman probably failed to mention this to you, or even taking your tv out of 'torch mode'.

    Widescreen TV's are really meant for HD and DVD.

    This is why it's always important to back off the sharpness and contrast settings from their factory defaults. I think most sets ship with the sharpness set to maximum.

    and the factory default setting for most all TV's when new is very high contrast and brightness. back those babies down.

    that's unfortunate... but rear projection tv's are the most susceptible to burn in. sorry

    It's permanent buddy, sorry. Burn-in is not curable short of replacing the CRT's. For a long time, TV's came with no warning to that affect. At least, none specifying the possible damage of displaying a 4:3 image on a 16:9 screen (with the black bars). But recently, I picked up a new Mitsubishi RPTV for the bedroom. It came with a big yellow tag on the lower left of the screen that says something along the lines of....

    "Displaying a 4:3 image without using stretch or zoom may cause permanent damage to this unit not covered under warranty."

    My HD box uses grey bars on the sides rather than the traditional black bars (as an option in setup). It's "supposed" to eliminate burn-in problems with CRT based displays. Whether it actually succeeds in that........ I have no idea, I always use the zoom as the bars piss me off.
    Go BIG or go home!

    If you have your contrast, sharpness, and brightness set properly, and use grey bars as opposed to black, you will not cause harm to your set.

    I would avoid gray bars period, unles you frequently vary what you are watching. I've seen uneven wear with gray bars also. I think I've seen more burned plasmas than anything.

    The manual for my Mitsubishi says you cannot use the grey bars more than 30% of the time or you risk burn in. Once you have burn in it is not correctable.

    May only be retention. :)

    Some screens have two modes of "burn in". The first is called retention. It goes away after a while. It is your first warning that you may be doing something wrong. The second comes some time later and is truely burned in to the screen. You have nothing to loose so play all widescreen stuff for a month and quite possibly the images will go away. If they go away then just try to vary between widescreen and 4:3 a little more.
