Question about Optoma EP719 XGA DLP PROJECTOR 2000L 2500:1 CONT DVI-D WITH HDCP Multimedia Projector
When my display comes up on the screen the Optoma logo is clear & stable. But then when I open my Power Point presentation the display on the screen seems to jump a bit as though it has a continued heartbeat or pulse. It began doing so a couple of weeks back during a seminar presentation, and today when I tested it, it did exactly the same thing - as though the projector has developed a heartbeat every couple of seconds.
It is one of the fan, it is bent or out of place and cause reptead disturbance at cyclic intervals. The projector must be taken apart and examined on the inside

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!
