Question about Optoma H30 Multimedia Projector
It is most likely getting too hot.
Make sure all the fans are clean. Make sure the projector is not mounted too close to the cieling. This may block vents in the housing.
If you have to, you may need to mount a small fan near the projector to blow into the vents. Make sure it blows in the right direction. You don't want it working against the fans inside the projector.
Just for a test, unmount the projector and run it on a table. This should tell you if the mount on the ceiling is causing the problem.

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!
