Question about Optoma EP719 XGA DLP PROJECTOR 2000L 2500:1 CONT DVI-D WITH HDCP Multimedia Projector
I just got done fixing this problem. A vertical white bar was at the left 3rd or so of the display. I open up the projector (which required taking a steak knife to the center screw column since there's a unique, tiny screw that has to be removed), removed the shielding, and ensured that all the connectors were snug. Many of them were crooked and not seated in their sockets. I also removed and reattached all the ribbon cables, including the one that goes to the color wheel. The vertical bar is gone now. I have let it run for about an hour now with no failure.

I have the same problem. Read another blog and they suggested that the tilt of the color wheel could be a problem. I have not had the opportunity to test it, but it may be right as the last time it was used it was okay until the "picture" was elevated (read: the machine was tipped up further). This would be an easy fix if this is the answer... just wanted to pass it on...

It's either pins that need to be reseated, or the Vertical display IC has gone bad. Open up the case, and make sure all connections are secure inside. If you are certain that they are all snug and nothing is loose on the board, then your problem is a faulty display IC. Replacing surface mount components is not for the faint of heart.

I don't have a solution but I bet the connector on the projector has a bad pin.

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!
