Hi. I noticed faint black horizontal lines on my partent's Transoinc DVD player, so I tried messing around with the settings (they didn't have the manual, apparently they don't believe in them) and suddenly everything went blank. I think what I did was to change the input from the red, white and yellow component cable to the S-video digital input. So now I can't see anything because I don't have a S-video tv.
What annoys me was there was no warning and there is seemingly no way to reset it.
