During normal viewing, be it through the aeriel, dtv or sky I can see faint vertical lines panning across the screen from right to left. Normally, this is not noticeable, but it is most obvious during dark lite scenes when the panning vertical lines are most obvious. Currently I don't have a DVD player attached.

This is a problem that's far too common among flat-panel and projection LCD TV's?and it's generally known as "vertical banding."
If the lines are there all the time or intermittent but in the same location it is an indication of a bad panel.
The panel driver can also be the cause of this symptom. Samsung panels have had issues with the connector that carries the LVDS signals to the panel itself, this is not serious and can be resolved and little cost.
These faint vertical bars (often most apparent when the screen is totally dark or displaying a solid background, like the sky) are defects that occur during the manufacturing process, and while the worst offenders are typically screened out, many more make it to store shelves.
Since you've pinpointed the banding and it's driving you nuts,also its under warranty, call the manufacturer and demand a replacement; in most cases, they'll capitulate and send you a new set, although you'll probably have to go to the trouble of packing and shipping back your defective TV (make sure the manufacturer covers your shipping costs).

There are two reasons for this fault. A fault smoothing capacitor at the video output voltage rail, or excess of screen voltage. These lines are called 'vertical retrace lines' technically.

Was the toner remanufactured/ compatible? Sounds to me like the doctor blade in the cartridge is 'gummed' up and not allowing the toner to flow evenly across the Developer roller......try another cartridge
