A very frustrating issue has been bedeviling me lately. Maybe someone here can help.
I was given an old HDTV. It’s an old dinosaur of a TV; a Samsung DynaFlat, made in 2003, with a CRT display. I figured this was a good excuse to buy a PS3, which I’d been wanting for some time, so I did that. I connected the PS3 to the TV and have been playing Metal Gear Solid 4 on it. There’s only one small problem.
Two vertical, purplish-colored bands appear on the screen. They are most visible when something dark is in the background. Incidentally they do not appear on ALL black backgrounds - a pure-black screen, like the loading screens on some games, don’t show them. But they appear most of the time, and always during gameplay. In MGS4, where most environments seem to be tan-colored and saturated in bright light, they’re often only very faintly visible, but when Snake moves into a darker area, then they are more obvious. They can get kind of distracting.
To help you understand what it looks like, I created this image which is an approximate representation of what my TV looks like under this condition. You can see those purplish bands running vertically down the screen, to the left and right of Kyle Maclachlan’s head. The ones in the picture are more exaggerated than the ones that I actually have on the TV. Also, in real life, the edges are more blurry, kind of gradually fading off, instead of the solid lines in that image. But the overall effect, I think, should be visible to you.
I tried monkeying with the color, brightness and contrast settings of the TV but to no avail - nothing I adjusted got rid of those bands.
Here’s something interesting: the position of the bands actually CHANGES every time I turn on the TV. Sometimes there’s one all the way to the left and another one slightly in the middle; sometimes there’s one right down the middle of the screen, and a slightly thinner one all the way on the right side; sometimes the bands are different distance from each other. So they are not in the same place every time. They change when the TV is turned off and on.
What is causing this annoyance? What can I do to fix it? Worst case scenario is, I just buy a new TV, which is not the end of the world, but it would be nice to save the money because I would be content using this one for gaming, if this problem could just be resolved. Is there some way of getting rid of these purple bands?
