Hi, same problem here. I bought 20 days ago a Samsung LE46C750 and I noticed same vertical darker bands. I contacted Samsung Support and, after 7 days in their laboratories and different tests, they said that it is not a defect and the panel is in their standards...
BTW I noticed that the vertical bands seems to fade after a couple of hours.
I'm very undecided whether to return the TV to the seller.
Ive got a problem with my brand new 3D Samsung LCD TV (ModelLE46C750)
I am getting light and dark vertical bands on the screen, noticeable when watching HD sources and particularly when there is fast camera panning.It shows up particularly when watching live sport and the camera pans quickly. I get this on normal source and 3d
At first I thought this was down to my Sky HD box and that the TV was showing up imperfections in the Sky feed, however I have just got a blueray hd DVD player and I can also see this on the DVD meaning it must be an issue with the TV Set.
The bands are quite light in colour, almost ghostly but they are none the less very annoying. Most people probably wouldnt notice them but as a bit of a TV geek I am defintely spotting them and they are beginning to irritate me.
Im trying to work out if this is just the TV sets performance generally or a possible fault - what do you guys think?
