Hi! The tv modeI I have is the Samsung ln40b530. I have videotron as my cable. Well, lately, Ive been noticing that whenever im looking at my tv guide, and i close it, I see like a quick green line on the middle top of the screen for a second while the picture is readjusting itself. It happens like 80% of the time. Im just wondering why it does this. I mean is this the tv or just videotron? If this is the tv, well, frankly, the green lines alone dont bother me, but what im also worried about is can this mess up the tv. I play my ps3 with my hdmi, and its amazingly good, but can these green lines affect the screen? O and, I watch cable through the channel 3 type thing.
