Because I can't seem to get any tech support I thought I would post here. My unit displays doted lines or just lines that do not go completely accorss the screen. They white or black or both. They appear fast and disapear. It is not my DVD players. It does not show up on my NEC 6PG Plus projetors test patterns. I am not a rich. This is extremely disappointing. Any help to fix it would be great but an alternative where If it is not fixable is good also. I would like a replacement unit if possible and I don't understand why I should have to pay anything for a new one if so. I can't beleave I'm supposed to entertain my mothers guest with this. I'm depressed. Please help.
