hmm, i'm fairly certain they're plugged in correctly as it works fine on interlaced. But i'll check that tomorrow before work (i'm on night shift right now). I've called the service center & they're going to send out a technician. I have a couple of other issues (very minor geometry issues at the very edge of the screen, & pretty nasty halos on objects in front of bright backgrounds if the sharpness isn't turned up to about 70%) & i have the 3 year service plan so i might as well make use of it. Overall the TV's great & these issues aren't really that big of a deal. (the halos are the biggest problem to me, but if you turn the sharpness up to 65-70% they go away & the image looks good, not what you'd typically expect with the sharpness that high). Hopefully, though, the technician will know what he's doing & be able to correct the problems. If they can't fix it, they give me a new tv, so i've got no complaints.
