Question about InFocus IN72 Multimedia Projector
White vertical line showed up. Took projector down and cleaned it. Started the projector again and white line was gone. Took about 5 minutes and the white line returned. Line is about 2 inches wide and is the full height of the picture
Several vertical white lines appear on the projected image. Tapping the unit sometimes has an effect, causing one or more of the white lines to disappear. The problem resolves itself after about 15 minutes after power up.
Omg, I just figured out why OUR projector was doing this! There was an adaptor plugged into it that we use to hook it up to cable to watch games/tv shows sometimes...once I unplugged that from the projector the lines dissapeared!

My EP719 had the same problem. Did it once, briefly, soon after I bought it, then not again until recently, when the line came back more frequently and wider.
The projector was 20 days past warranty, and the company would not honor. So much for customer satisfaction and loyalty. Last piece of Optoma equipment I will ever buy!
Anyway, I found a web item on another model of Optoma projector with the same problem. The solution this guy tried was -- I kid you not -- rapping on the thing. With nothing to lose, I tried this on mine. Tapped lightly on the top and noticed a change in the width of the line. Hmmm ... it was sensitive to this.
Tapped harder. The line got narrower. Rapped pretty hard -- thump! -- and the line disappeared.
Since then I have been running the projector for hours, turning it on and off, letting it cool down, starting it up again. And the line seems to be gone. It may come back, of course, so this gonzo fix may not be permament. But if it works while I'm using it at a presentation, think of the amusement it will cause!
