SAMSUNG LE46M86BD LCD issues with artifacts on text and occasional verticals

[admin_exported]

Has anyone else had this problem where you see moving square white blocks (is this 'dot crawl?) occasionally on edges of text or some vertical surfaces? It's particularly evident in the white channel 4 motif they show at the end of their advert breaks etc.

Or is this just an issue with this or any other lcd sets?

Thanks for any insight.. 

<edit> Forgot to mention.. Additionally, sometimes after I've been viewing my pc on the set, via HDMI, when i then go back to my vision box input (also HDMI), there are hundreds of little dark vertical lines across the whole image. They do disappear if I switch off then on again, but I'm just worried I've got a lemon set and things could get worse. I'm considering asking Dixons for a replacement, but worried that, A) they'll only offer a repair, or B) they'll say they can't find a fault and I'll have paid to send it back for nothing. I have had it since March

Can't say I've had this issue myself........

Im not entirely sure sure what your trying explain but if its artifacting around edges try turning down any picture enhancements like noise reduction and sharpness settings that may help

I know what you're saying but I have all my enhancements like noise reduction and auto contrast off and sharpness at zero. Thanks for the thought, though.
