    Rob,
    I have noticed such ghosty shadowy lines/columns on dark grey screens on every TV set I have ever owned - even an Amiga monitor, in various houses and locations. I'm as puzzled as you are.

    Hi,

    I've just had my Samsung W32W8VD 32inch widescreen TV delivered - it's a cracking set (although proabably not in the same league as the Sony & Panasonics :) ).

    Anyway, I've noticed that when the screen is black (or during dark scenes like at the begining of the Matrx), there are faint vertical stripes on the left half of the screen - regardless of input medium (DVD, cable, video & ariel all give the same bars).

    Also when there's white letters on a black screen (titles, credits etc) I see a 'streaking' effect - almost as if the contrast is too high (it's not).

    Any other time the picture is sharp & crisp, colours are great - it's just when the screens dark I get these effects....

    ... could these effects be a defect or are they just a consequence of not buying a top of the range Sony/Panny. I'm fairly sure they're not gauss effect lines from speakers (this is a different symptom & causes a different effect)

    I've check a couple of reviews and this problem hasn't been mentioned. I also bought the TV mail order so I have nothing to compare it against (No shops in Bristol sell this particular model).

    I have a tech support guy comming around on Wednesday to check it, but I thought I'd throw it in here to see what you guys think... as I'm sure he'll give some cock & bull story to avoid replacing it.

    If anyone has any thoughts on my little problem please let me know.

    Cheers,

    Rob

    I have a Toshiba 46 RP tv and I notice the same effect but only when there is no picture. In other words, when the picture is being projected 'black' I can't see the lines, but if I look at the plain black screen, I can. When 'blue screen' is on, it is perfect.It does not affect my enjoymeni though, the pluses far outweigh the minuses. I doubt if if is a 'fault' as such but I would be interested to hear what the engineer says about it. Keep in touch,

    Dave

    'Polarisation'. This was the explanation that I got for the lines on the TV. The two guys that came over to have a look at it where very nice; thay also seemed to know what they where talking about. They've taken the TV away yo the lab for further investigation, although tye did mention that there might not be a solution. V Happy with the service though (they're contracted through QED for tech support).... will keep you posted as to the outcome!

    I would be interested to hear the outcome as well. I have a Sony 4:3 25" set and have exactly the same problem. I did find out the brightness/contrast was turned up way too much and turned it down but its still slightly visible.
    If I could ignore it I would but it still jumps out at me when i'm watching a movie, particularly a DVD because the rest of the picture is so good.
    It would be interesting to see how many others notice this.

    ... The techies never got to the bottom of this problem - last time I called they were waiting on info from Sumsung Korean. I called QED and asked for a replacement which they agreed to. Got the replacement set last week - no funny lines, so I'm happy!!!
