Hi all, this is my first post here so please be gentle! However, I thought you should be aware of this and also I would be interested to know if others are having the same problem. Firstly I'm not hugely into TV but decided to buy a new IDTV to replace my very old set. I read a few reviews and bought a Sony KD28DL10U from Empire Direct. The TV was delivered; I plugged it in and it worked fine; looked good. However, within a day or so I noticed that on some light colours there were vertical green and magenta bands on the screen. This was only noticable on 'thin colours' although the effect could be enhanced by playing with the colour/contrast/brightness. It is only apparent in digital mode not analogue or DVD playback (which is superb). I complained to Empire Direct who said they would replace it as long as an engineer confirmed the problem A Sony authorised engineer visited - he said although the set was a new model he hadn't seen anything similar on the previous idtv model. It was clearly a problem and he suggested I get a replacement. The replacement arrived today (no problems with Empire Direct who have handled this OK) and having plugged it in etc. I find that the problem is still there but much fainter. Indeed if I hadn't had the problem first time round I doubt I would have seen it. If you have one of these tv's can i suggest you choose either a blank channel or one just showing the light brown wallpaper(Wallpaper 2 in setup I thinK) then play with the colours/brightness etc and see if you can see it. There are distinct vertical bands (a few centimetres wide) on mine. I then phoned the engineer back who said he has now seen it on another set since seeing mine and he suspects that 'it is just the way it is'. I've since phoned Sony UK who tell me they have no other reports of this problem. Can I ask if anyone else has this problem or any suggestions to make? I am probably going to reject the set under The Sale of Goods Act and get my money back. This is a shame because I think that the set is otherwise excellent.
