    I have a CRT TV (SDTV) and when i play 16:9 movies and chose Pan n Scan on my DVD player, it doesn't work. There are still big black borders on the edges.

    And I just noticed that the bottom black border is taller than the one on the top.

    Are these commercial DVD discs?

    What happens when you select letterbox? Do the pictures reach the left and right edge? Do 4:3 discs play properly?

    The DVD player Pan/Scan feature normally centers a 16:9 playback at full height. The Pan/Scan feature (left to right pans) depends on disc support.

    yes it reaches left and right edges when i selected letterbox. and letterbox is the same with pan n scan. when i turn to pan n scan, the same. when i turn to letterbox, the same.

    yes 4:3 discs play properly.

    and anyway, what about the bottom black edge? when the video is not 4:3 there should be black edges top and bottom right? but my bottom black edge is big compared to the one on top.

    Must be unique to that player. Have you tried another player on that TV?

    This could be your TV displaying the picture off center. How much difference in size is there between the top and bottom bars?

    Make yourself a DVD with a 4:3 overscan test pattern and see how far off center your TV is.

    the top is about half the height of the bottom.

    If you're talking about a 16:9 movie on a 4:3 display that is probably just a matter of the TV displaying the picture off center.

    Regarding the Pan-and-scan setting on the DVD player -- as I understand it, the DVD itself must support pan-and-scan (instructions embedded into the the video data that instruct the player what part of the frame to show), and most don't. For DVDs without the pan-and-scan data you will need to use a zoom function (if your player or TV has it) if you don't want to see black bars and don't care about mindlessly cutting off the sides of the frame.

    Does it show off center in normal TV tuner mode? What model TV is this?

    Centering would be an internal service adjustment. If it is that far out you would need a full expert alignment.

    in TV tuner? no. it does not picture off center. Model? Sony. This is an old CRT TV, umm...bought about 6-7 years ago.

    i have this setting in my DVD player that is 16:9 to make non-4:3 become fullscreen or if not taller on my TV. Thus, movies with 1.9:1 ratio and below becomes fullscreen while about aspect ratio of 2:1 and above does not become fullscreen but taller. So the 'picture off center' of the movies will only be visible in those ratios where edges can be shown, right?

    tried it on 2 DVD players and still the same. Durabrand, and guess what? a chinese product with no brand printed on it (my father bought this without my 'permission'). But the DVD works fine for me, even better than the Durabrand since it works on some DVDs that Durabrand can't play.

  12. Inside the TV there are adjustments for the width, height, and centering of the image. These are usually not accessible to the consumer.

    Normally the centering adjustments affect all modes so if only on DVD input, something else is wrong. I'd just live with it. Figure a Sony alignment will cost $200 or so.

  14. I doubt it's just the DVD input. He just doesn't notice on regular TV broadcasts because a 4:3 image being off center by 3 percent isn't noticeable on a CRT which probably overscans by about 5 percent.

    This is the typical failure pattern for an older CRT TV. As phosphors "wear" they tend to dim. This often happens to red first causing a picture color shift to green or blue.

    As the phosphors dim, the user compensates by turning up the brightness. Eventually this causes the high voltage power supply to overload and go non-linear causing convergence and linearity shifts. Internal adjustments can help for a period of time but eventually the high voltage supply or CRT fail requiring replacement.

    Your TV could probably be restored with a full service internal alignment but at about half the cost of a new TV. Talk to your service shop about prices.

    I looked for a channel that does not broadcasts 4:3 then i found one (I really don't watch TV stations/channels a lot, only movies) then i found one. It's the same, the bottom edge is really taller.

    I really forgot if my TV was like this, i just noticed this weeks ago:
    -->when i watched a movie with an aspect ratio of about 2.11:1 and my DVD player was set 16:9 wherein this resulted to only showing the bottom black edge, without any top edge.

    Then that started me noticing that the picture is not on center. I'm not really sure that my TV is like this years ago.

  17. As edDV mentioned, CRTs are prone to that type of problem as they age. It's one of the reasons they overscan. If the picture shifts off center it's hard to tell.

  18. You can look on the internet for how to get into the service menu and center the picture. On a TV that old if you look enough you can probably find the adjustments and what they do. It's probably called VCEN for vertical center. Sony TVs can be very poorly adjusted from the factory.

    Make SURE to write down original settings before changing anything, they are specific to each TV and are the only way to get back to where it was if you adjust something you shouldn't. As long as you write down settings before making adjustments you should be OK.
