I am new to DLP TV's. Just picked up this one used. It needed a color wheel. Replaced it with no problems. I am noticing what looks like static lines on the screen, 6 of them, running top to bottom, evenly spaced apart. Depending on what's being shown on the screen at the time, they aren't always visible. I tried the tv in different HD STB locations...same result with HDMI cables and component cables. I hooked up my JVC progressive scan DVD player, and they show up while playing a DVD too. Any thoughts? I wish I could better describe the issue...just imagine faint squigley static lines that run vertically and are evenly spaced.
