Vertical white line

There is a vertical white line in the middle of the projection which began yesterday. Not on the computer image, shows up when warming up at the `t´of Optoma logo. Tried resetting, turned off and back on, no luck.

Re: Vertical white line

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!

Thin vertical line appears on projector

I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.

White vertical line in the center of projected image

I have a Dell 2400MP projector that had the same problem of vertical white lines appearing over the screen.

This may seem like a simple solution, and I don't know if this will work for you, but the way I solved the problem was simply to press the bottom side of the projector, until the white lines disappear . Until now, the problem has yet to resurface.

Here's some simple steps:
1. Turn on projector
2. Connect projector to computer
3. Focus projector
4. If white vertical line appears, firmly press underside body of projector
5. See if vertical white line disappears
6. If not, try slowly pressing other parts of the body of the projector and see if white lines disappear.
7. If solution doesn't work, you may need to send it to the service center.

Hope this solution works for you.

Best Regards,

White vertical lines in image w/ 2 inch black bar horizontal.

the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.
