I have a Samsung WS28M64 TV which works fine apart from one annoying problem. In dark scenes with low contrast a light patch appears down the left side of the screen. If there is a decent patch of brightness in the scene, the picture is fine. But when there is very little contrast the light patch appears down the far left of the screen and the affected area of the picture goes a little cloudy. Does anyone know what causes this and if it can be corrected ?. What makes it worse is that this is in fact my 7th WS set! (of various different brands) and it's for the upstairs bedroom so with each WS TV I've had to lug the bloody thing upstairs only to find that there's something wrong with it and have to lug it back down again!. My first set was a super market brand which had a problem displaying subtitles correctly. So I swapped it for a Philips 6006 but that had a slanting image and grainy picture, so I swapped it for another 6006 but that had the same issues. I then went for a Sharp 28JW but that had a problem where the the background of the image would erratically flicker whenever the set was in 16:9 mode, so I swapped that for another Sharp 28JW but that too was the same. I then opted for a Panasonic DK1 but that had some of the worse voltage regulation I've seen on a WS set and that resulted in the picture warping whenever the screen was bright - back it went. After that I was so sick with widescreen CRT's that I lost interest in buying one for the best part of a year. Now I've decided to try again and opted for the Samsung 28 pure flat only to discover the previously mentioned white patch issue. I'm really hoping that it's something simple because I don't think I can face the hassle of carrying it back downstairs, boxing it up and sending it back for a replacement only to find that the replacement is just the same after I've lugged it all the way back upstairs again. Please help!.
