picture keeps adjusting

[ronaldo]

I have a philips 30-inbch widescreen direct view tv. While watching last nights col-colo state game on in 1080i, the picture started seemingly making adjustments...
i don;t know if this was because of the ticker at the bottom of the screen or because of graphics, but even when the picture was void of graphics and was just showing the game..occasionally the picture would readjust itself.
Anyone know why or what this is and if it's correctable?

There's an option under "Features" section of the menu called "Active Control." If left on, it will try to automatically tweak the picture to display what it determines is the correct sharpness/noise reduction settings.

I'd reccomend just leaving it turned off.

I notice this a little bit on my 55". It seems like the picture creeps to one side very, very slowly over time, until some threshhold is reached that causes it to readjust itself back to the original position. Only appears to be getting off by a few pixels. Needless to say, you have to be paying REALLY close attention to notice it. I never would have seen it if not for the video game I was playing.

Keving, some TVs move the image side to side to help prevent burn lines (the lines that appear at the interface of 4:3 shows and the "grey or black bars" and also other static images that appear on screen.)

This should be outlined in the owners manual and is given as a "feature" on some TVs.

Makes sense. That might be what Philips refers to as Automatic Phosphor Aging Compensation (APAC), since I haven't really found out yet what exactly they do to compensate for aging phosphors in certain areas of the screen over other areas.

Yep, that's what it is...

Automatic Phosphor Aging Compensation (APAC) periodically shifts the television picture in tiny increments that are large enough to blur image retention. Although this helps, it will not eliminate burn lines, or larger logos, etc.
