I have problem which is going to drive me crazy . In dark scenes, bright light sources are causing white horizontal lines. Lines are drawn only to the right side of the light source, starting from the light and ending to the border of the picture. I have already make some adjustments for this with contrast and brightness, those won't help. I have also tried two different RGBHV cabel, this won't help eather. I have heard that lousy (nonstable) power supply can cause this kind of behaviour, because drawed line won't be stabilized enough after bright light source. Could this be the explanation? Is there anything to do for this? Power supply mods? Projector is Barco data 708 with Skyworth 1050D progressive dvd player and using VGA output. Player outputs RGBHV signal and I have connected the player to the Barco with T connector for combining horizontal and vertical syncs. Barco has only RGBS input. Can this affect to those white lines?
