Hi, I have had a Xelos 5381 ZW for about 2 1/2 years and I have been very happy with it. Especially after adjusting its geometry a tad. However, I have now noticed horizontal lines about 3/4 to 1.5 inches apart across the screen with a diagonal flyback from the right end of each line to the left end of the next line. These are only noticeable when there is black on the screen (as in letterbox or side bars or just a dark scene.) I first thought they were from my DVD, but I can also see them on SD digital broadcasts (via STB) as well as analogue broadcasts. Interestingly they are not visible on the blue no signal screen. Any ideas? What causes them? Can they be fixed or adjusted out of view? Does this imply a component about the die?
