After transporting my Optoma HD32 projector from work to home, I turned it on and saw vertical white lines spaced evenly across the entire display. I am wondering what the cause of this is and how to fix it (and prevent it). It has actually happened before after moving it, but the lines went away after a few minutes on their own. This time, they have not gone away after 30 minutes. I have tried resetting the projector settings, tried turning it off and on again (twice), but the lines remain. Googling hasn't turned up much, I did see one person that suggested hitting the projector with your hand. I eventually tried this and it did alternate the thickness of the lines, but did not clear them. Any suggestions (especially if you have experienced this) would be greatly appreciated. Thanks!
