Advertisements Has anyone ever had grey horizontal lines going through SD channels? I am using Spectrum cable, with a cable card. I already replaced the TV, thinking it was the 14 year old plasma tv burning out, causing it. The lines only appear on SD channels. If I zoom the screen from the small box, to wide screen, to full screen, the lines move with the picture. I put some attenuators on the line, in increments of 3. That got the corrected and uncorrected errors down near zero, but didn't affect the picture. HD content, Roku, all of the smart tv stuff look fine. It's only SD shows. I'm also experiencing some audio pops that sound like static, on one channel only. Anyone had similar issues?
