Vertical Lines on Samsung 42" RPTV

My 2 week old 42" Samsung DLP is exhibiting a problem: Regardless of
input source, even on test patterns, I am seeing faint vertical lines
about an inch apart
across the screen. They are most noticeable when viewing lighter
colors. On some colors, like blue, they do not appear at all.

(Please do not advise me to have a tech look at it since it is under
warranty - I know to do that and am awaiting a callback from the shop.)

Has anyone ever seen this kind of thing on their sets?
